Important Audi Antifreeze Draining Flushing Filling Info

Draining alone can leave as much as 30 to 50% of the old antifreeze in the engine block. Before you change your antifreeze please read some important information regarding:

Important Audi Antifreeze RemindersIncorrect Audi Antifreeze

As an independent Audi service garage with over 23 years of hands-on experience, we know what fails on Audis and why. We feel that changing your fluids is one of the most important preventive maintenance routines. Yet, for many Audi owners, this seems to be one of the most neglected area of maintenance. Thoroughly flushing your fluids at the proper intervals can help your Audi reach 150,000 miles and beyond!

#1 Audi Antifreeze Change Intervals

Blauparts recommends changing 'long life' Audi antifreeze every 3 to 4 years. Why? The combination of chemical additives contained in antifreeze, responsible for retaining alkalinity and inhibiting corrosion within the engine's cooling system, over time become depleted. Similar to oil, Audi antifreeze eventually breaks down, becomes weak, and "gets dirty." For maximum corrosion protection and prolonged engine life, flushing Audi antifreeze every 3 to 4 years (40,000 – 50,000 miles) is imperative. Thoroughly flushing your Audi's antifreeze is most convenient when done during timing belt replacement.

#2 What Type Of Audi Antifreeze

Use ONLY Audi Vw G11, or G12 approved anti-phosphate, anti-amine, anti-phosphorous antifreeze! Do NOT use regular store bought antifreeze, which typically contains ethylene glycol and doesn't correspond with the specifications of an Audi cooling system. The specification or type of Audi antifreeze required for a particular model can be found stamped on the expansion tank (e.g. G11 or G12) as well as in the owner's manual under the antifreeze section. It's also good to note the color of your antifreeze (e.g. pink or purple). See Audi Antifreeze Features section below for further Audi antifreeze information and specifications.

What happens if you don't use correct approved Audi antifreeze?
Inferior antifreeze has an adverse reaction within an Audi cooling system. Poor quality antifreeze contaminates the system and eats away at metal, rubber, and plastic components. Obvious external indicators are bulging antifreeze hoses and white calcified residue oozing from antifreeze hose clamp mating areas (See Image 2). Not so obvious is lime and scale deposits that begin to build-up in the radiator core, restricting antifreeze flow and causing the engine to run hotter (especially in summer and warmer climates). All of this eventually causes serious engine problems (i.e. water pump failure - See Image 1). If your antifreeze is green or brown in color, thoroughly flush your cooling system immediately! You'll notice similar warnings in your owner's manual under the antifreeze section.

#3 Audi Antifreeze Concentration

Remember to check the concentration (pH) of your Audi antifreeze on a regular basis. It's especially important to maintain the correct Audi antifreeze concentration during winter to protect your system against freezing temperatures. If your antifreeze concentration is weak, change it. Over time, weak or contaminated antifreeze (incorrect pH) can cause serious engine problems (i.e. water pump failure, as mentioned above). It's also important to note that approved Audi antifreeze comes in concentrated form. You MUST dilute the antifreeze using DISTILLED water to a 50/50 concentration. DO NOT mix normal tap water with antifreeze. Tap water varies in pH, mineral, and chemical content and can adversely affect your new antifreeze and cooling system. See Important Antifreeze Draining Flushing Filling Info section below for more information.


PLEASE NOTE:

Blauparts recommends topping off your expansion tank with the same type of coolant that is currently in your Audi cooling system. This ensure the purity of your cooling system. Owners who are currently using G12 coolant may wish to upgrade to the latest G13 purple coolant the next time they thoroughly flush the cooling system (i.e. during timing belt replacement). Please read our Topping Off section.

Even though the latest G13 coolant is backward compatible, Blauparts recommends thoroughly flushing your cooling system, when upgrading to a different type of coolant. This maintains the purity of the cooling system.

Blauparts only stocks coolant that meets approved Audi G13 and G12 coolant specifications.

Ravenol Coolant

Why Choose Ravenol German Antifreeze?

Ravenol coolant is superior to leading brands of domestic and European brands of glycol based engine coolant. If your looking for an OEM replacement coolant for your Audi that has the "upper edge" in exceptional performance qualities, look no further! Why?

Advanced Audi Antifreeze Corrosion Protection

Ravenol Audi coolant is classified as a long life / lifetime coolant that provides stable and consistent corrosion protection for the long life of the engine. Ravenol coolant was specifically engineered for advanced high performance European engine designs and metal alloys. An environmentally friendly coolant that contains a unique OAT (organic acid technology) package that is phosphate, nitrite, and amine free. Ravenol's OAT package reduces overall acidity within the cooling system, extending the life of cooling system components and related engine components (i.e. water pump, alloy radiators, plastic radiator and end caps, cylinder head manifolds, coolant hoses, cast and alloy engine blocks). The advanced profile package prevents scale build up and deposits in the cooling system thereby improving cooling system circulation.

Exceptional Cooling Performance

Ravenol Audi coolant outperforms other leading domestic and German brands of coolant. Ravenol's unique formulation and molecular profile improves cooling system flow for guaranteed heat transition away from vital internal engine components, especially the cylinder head. The undiluted boiling point of Ravenol's coolant is 370°F / 175° C, significantly reducing the risk of boil overs in high temperature climates and high performance RPM engine designs. Ravenol's coolant also provides maximum frost protection in extreme cold climates (i.e. -37° C 50/50 ratio and up to -52° C 60/40 ratio).


Important Audi Antifreeze Draining Flushing Filling Info

Flushing Audi CoolantPictured Example. Blauparts purchased a used 1997 Audi A4 with approximately 90,000 miles, which had 1 previous owner. The previous owner had every service record from the date of sale, regular oil changes, preventative maintenance, and took really good care of the car. However, note the sediment or contamination of the G12 antifreeze that was removed when we thoroughly flushed the system. Even when using approved antifreeze, years of continuous circulating through the engine causes a measure of sediment to buildup. Changing Audi Antifreeze Service Bulletin

The combination of chemical additives contained in antifreeze (even long-life antifreeze), responsible for retaining alkalinity and inhibiting corrosion within the engine's cooling system, over time become depleted. Similar to oil, antifreeze eventually breaks down, becomes weak, and "gets dirty." For maximum corrosion and prolonged engine life, flushing Audi antifreeze every 3 to 4 years (40,000 – 50,000 miles) is important.

Draining Audi Antifreeze

Do you want your Audi to reach 150,000 miles and beyond; or your new water pump to last 60,000 to 90,000 miles? Then, it is important to replicate the cooling system to a like new factory condition. Simply draining is not enough. Draining alone can leave as much as 30 to 50% of the old antifreeze in the engine block. Your cooling system should be free of any and all contaminants! You can not be lazy when it comes to antifreeze flushing and water pump replacement! Cutting corners now adds time, labor, and money later.

It's the installers responsibility to take the necessary time to thoroughly flush the cooling system. It has been noted that due to time constraints, inconvenience, and profit, many individuals, mechanics, and repair shops do not take the extra time needed to thoroughly flush the entire cooling system. Thoroughly flushing the antifreeze involves the engine block, radiator, heater core, and hoses.

Premature water pump failure (bearings and seals) can occur if you don't take the time to flush the entire cooling system and it's related components. Often when problems arise, such as an antifreeze leak, the new Audi water pump is blamed as the cause when in fact the opposite is true. It's usually because the installer neglected to follow this important step.

Flushing The Audi Cooling System

It is imperative that the Audi cooling system be thoroughly flushed of all accumulated silt and sediment buildup. All aftermarket cooling system additives, or stop leak products that may have been added to the cooling system (past or present) should be completely flushed! Thoroughly flushing the cooling system involves the engine block, radiator, heater core, and hoses.

Only use tap water to flush the entire cooling system. Do NOT use cooling system flush products. Many of these agents contain muriatic and/or other acids. Remnants of these acids left in the cooling system can cause your new Audi water pump to prematurely fail (see example images on related water pump replacement page).

Filling and Topping Off The Audi Cooling System

Use ONLY Audi VW G13, or G12 approved antifreeze! Do NOT use regular store bought antifreeze, which typically doesn't correspond with the specifications of an Audi cooling system. Most Audi antifreeze comes in a concentrated form. You MUST dilute the antifreeze using DISTILLED water to a 50/50 concentration. DO NOT mix normal tap water with antifreeze. Tap water varies in pH, mineral, and chemical content and depending on these factors can adversely affect your new antifreeze and the cooling system. Never fill or top off with full concentrate G13 or G12 Audi antifreeze. Your Audi antifreeze should never exceed an antifreeze ratio of 60%. If it's over 60%, an inefficient Audi cooling system will result, decreasing flow through the radiator along with poor heat transfer through the engine block.

Important Reminder: Make sure that your local quick lube or mechanic isn't adding or topping off your system with incorrect antifreeze. Mixing factory approved antifreeze with any other antifreeze will cause an adverse chemical reaction with the existing antifreeze and contaminates the cooling system, thus affecting the longevity of the Audi water pump. If your antifreeze is green or brown in color thoroughly flush your cooling system immediately! You'll notice similar warnings in your owner's manual under the antifreeze section. Read the warnings on the antifreeze antifreeze bottle regarding improper use being harmful or fatal.

How To Flush Audi Antifreeze - Basic Overviews

Flushing your Audi's antifreeze is most easily done when replacing your timing belt.
Refer to the factory manual for Audi cooling system capacities and mixture ratios.
We recommend having an A.S.E. certified Audi mechanic change your Audi antifreeze. Always wear gloves and safety goggles when handling Audi fluids.
This is a basic overview of what is involved when flushing Audi antifreeze. It is not intended to replace the factory manual.
Please refer to the factory manual for detailed instructions.

How To Change Engine Antifreeze On An Audi 4 Cylinder (1997 - On) :

  1. When the engine has cooled down, remove the Audi antifreeze tank cap.
  2. Draining the Audi antifreeze from the 4cyl cooling system:
    Remove the lower radiator drain plug from the lower front of the radiator (Audi A4, Vw Passat). Remove the passenger side lower radiator hose. Remove the outer Audi antifreeze hose that connects to the oil cooler. To drain the heater core you'll need to remove the hose on the antifreeze flange or transfer pipe located on the back side of the engine. This hose goes from the cylinder head to the heater core.
  3. After the system is done draining, put the Audi antifreeze tank cap back on. Carefully work off and remove the smallest hose that is connected to the top of the Audi antifreeze tank. Be careful, the tank nipple likes to crack and break off.
  4. With a blow gun and compressed air on low, carefully insert the blow nozzle into the small hose. Wearing safety goggles, carefully force the air out so that any Audi antifreeze that's still trapped in the cooling system is released.
  5. Reinstall the Audi antifreeze drain plug. Reinstall the antifreeze tank hose(s). Fill the Audi cooling system with distilled water. Start the car and air bleed the cooling system as outlined in the factory manual. Run the car until the cooling fan comes on.
  6. Repeat steps 1 through 5 until the water comes out clean.
  7. Verify that you have the correct anti-phosphate anti-amine G11 or G12 Audi antifreeze. If it's full concentrate, mix a 50/50 ratio per the Bentley manual. Fill your Audi cooling system with this 50/50 mixture. You MUST dilute the antifreeze using DISTILLED water to a 50/50 concentration. DO NOT mix normal tap water with antifreeze. Tap water varies in pH, mineral, and chemical content and depending on these factors can adversely affect your new antifreeze and the cooling system. Note: Some factory Audi antifreezes sold by dealers are already premixed and do not require further dilution.
  8. Run the 4cyl engine and check for any Audi antifreeze leaks.
  9. Top off the antifreeze tank to the fill line. Do not overfill.
  10. Using a permanent marker, write 'G11 or G12 Antifreeze Only' on the Audi antifreeze tank.
  11. Be environmentally responsible and dispose of your old Audi antifreeze properly.

How To Change Engine Antifreeze On An Audi 5 Cylinder:

  1. When the engine has cooled down, remove the Audi antifreeze tank cap.
  2. Draining the Audi antifreeze from the 5cyl cooling system:
    Remove the lower radiator hose. Only about 75% of the Audi antifreeze will drain, the rest is in the engine block and heater core. To drain the heater core you'll need to remove the hose on the antifreeze flange or transfer pipe located on the back side of the engine. This hose goes from the cylinder head to the heater core. You can also drain the engine block by removing the thermostat housing or the small 6" hose adjacent from the thermostat housing. This hose connects to the steel tubing that runs along side the engine block to the back of the engine.
  3. Reinstall the hoses. Fill the Audi cooling system with distilled water. Start the car and air bleed the cooling system as outlined in the factory manual. Run the car until the cooling fan comes on.
  4. Repeat steps 2 through 3 until the water comes out clean.
  5. Verify that you have the correct anti-phosphate anti-amine G11 or G12 Audi antifreeze. If it's full concentrate, mix a 50/50 ratio per the Bentley manual. Fill your Audi cooling system with this 50/50 mixture. You MUST dilute the antifreeze using DISTILLED water to a 50/50 concentration. DO NOT mix normal tap water with antifreeze. Tap water varies in pH, mineral, and chemical content and depending on these factors can adversely affect your new antifreeze and the cooling system. Note: Some factory Audi antifreezes sold by dealers are already premixed and do not require further dilution.
  6. Run the 5cyl engine and check for any Audi antifreeze leaks.
  7. Top off the antifreeze tank to the fill line. Do not overfill.
  8. Using a permanent marker, write 'G11 or G12 Antifreeze Only' on the Audi antifreeze tank.
  9. Be environmentally responsible and dispose of your old Audi antifreeze properly.

How To Change Engine Antifreeze On An Audi V6:

  1. When the engine has cooled down, remove the Audi antifreeze tank cap.
  2. Draining the Audi antifreeze from the V6 cooling system:
    There is a 8mm Allen drain plug on the back side of the subframe cross member offset to the drivers side. It is recessed about 1 inch into the casting of the engine block. You'll probably need a flash light to find it. To drain the heater core you'll need to remove the hose on the antifreeze flange or transfer pipe located on the back side of the engine. This hose goes from the cylinder head to the heater core.
  3. After the system is done draining, put the Audi antifreeze tank cap back on. Carefully work off and remove the smallest hose that is connected to the top of the Audi antifreeze tank. Be careful, the tank nipple likes to crack and break off.
  4. With a blow gun and compressed air on low, carefully insert the blow nozzle into the small hose. Wearing safety goggles, carefully force the air out so that any Audi antifreeze that's still trapped in the cooling system is released.
  5. Reinstall the Audi antifreeze drain plug. Reinstall the antifreeze tank hose(s). Fill the Audi cooling system with distilled water. Start the car and air bleed the cooling system as outlined in the factory manual. Run the car until the cooling fan comes on.
  6. Repeat steps 1 through 5 until the water comes out clean.
  7. Verify that you have the correct anti-phosphate anti-amine G11 or G12 Audi antifreeze. If it's full concentrate, mix a 50/50 ratio per the Bentley manual. Fill your Audi cooling system with this 50/50 mixture. You MUST dilute the antifreeze using DISTILLED water to a 50/50 concentration. DO NOT mix normal tap water with antifreeze. Tap water varies in pH, mineral, and chemical content and depending on these factors can adversely affect your new antifreeze and the cooling system. Note: Some factory Audi antifreezes sold by dealers are already premixed and do not require further dilution.
  8. Run the V6 engine and check for any Audi antifreeze leaks.
  9. Top off the antifreeze tank to the fill line. Do not overfill.
  10. Using a permanent marker, write 'G11 or G12 Antifreeze Only' on the Audi antifreeze tank.
  11. Be environmentally responsible and dispose of your old Audi antifreeze properly.

How To Change Engine Antifreeze On An Audi V8:

  1. When the engine has cooled down, remove the Audi antifreeze tank cap.
  2. Draining the Audi antifreeze from the V8 cooling system:
    There are 2 drain plugs. One on the drivers side and one on the passenger side of the oil pan. To drain the Audi antifreeze from the radiator, remove the lower passenger side radiator hose.
  3. After the system is done draining, put the Audi antifreeze tank cap back on. Carefully work off and remove the smallest hose that is connected to the top of the Audi antifreeze tank. Be careful, the tank nipple likes to crack and break off.
  4. With a blow gun and compressed air on low, carefully insert the blow nozzle into the small hose. Wearing safety goggles, carefully force the air out so that any Audi antifreeze that's still trapped in the cooling system is released.
