What to replace while changing the Audi A6 timing belt on the 2.7T 30 valve engine.

IMAGE DESCRIPTION Apart from the timing belt itself the Audi A6 2.7T 30 valve engine's timing belt system consists of 5 serviceable timing belt components. One is the water pump that is driven by the timing belt. Second is the fixed idler bearing, located on the driver side of the engine block.

Third is the timing belt tensioner system, where components work in sync with each other to guide and provide variable tension to the timing belt. This system consists of a tensioner, tensioner lever, and a hydraulic tensioner damper.

Before going through the significant work of taking your car apart for timing belt replacement, please consider the following:

Looking To Save Money... "Can I Just Replace the Timing Belt?" Simply changing the Audi A6 timing belt isn't enough. Why? Around the timing belt service interval (75,000 miles), due to age the integrity of the tensioner(s), damper, water pump, and other seals and o-rings are at the end or very near the end of their service life. Some individuals make the mistake of only replacing the timing belt. Then, 10,000-20,000 miles later, their new timing belt fails due to tensioner, idler bearing, or water pump failure.

Tensioners

Why replace your Audi A6 timing belt tensioners during timing belt service? Just as the timing belt has a designated service life and subsequent change interval, so do the tensioners and idler bearings. It's true that timing belts can get old, begin to crack, and eventually fail. However, it is just as common for the timing belt tensioners and/or idler bearings to fail, thus causing timing belt failure.

How can the tensioners cause a timing belt to fail? Most tensioner bearings contain a set amount of grease behind the seal. This grease provides ample lubrication and ensures tensioner reliability for the designated life span (75,000 miles). During engine operation, constant thermal temperature fluctuations eventually cause the bearing's grease to breakdown and loose it's lubricating properties. Over time, this results in unwanted bearing play and eventual seizure. If a timing belt tensioner has too much play or seizes, the timing belt can become misaligned, or begin to 'burn up' and shred, causing engine failure. Thermal temperatures also affect the timing belt causing the material composition of the belt to change anWad accelerates it's life span, often resulting in premature failure.

Water Pump

Why replace your Audi A6 water pump during timing belt service? It makes sense from a labor standpoint since timing belt dis-assembly is required for water pump replacement. The water pump is driven by the timing belt and contains an internal sealed bearing that has a life span similar to the timing belt, tensioner, and idler bearings. The internal bearing and seals of an Audi water pump can weaken and is the primary reason why a water pump eventually fails.

Thermostat

Why replace your Audi A6 thermostat during timing belt service? The thermostat and housing is located behind the timing belt on the passenger side of the engine. It makes sense from a labor standpoint, since timing belt dis-assembly is required for thermostat replacement. The engine temperature is controlled by the thermostat. Near the end of it's designated service life the thermostat spring temper changes. This causes the thermostat to open too much allowing the engine to run cooler, resulting in poor fuel optimization, decreased fuel economy, and less horsepower.

Valve Cover Gaskets & Cam Chain Tensioner Gaskets

Why replace your Audi A6 valve cover gaskets and cam chain tensioner gaskets during timing belt service?Audi A6 Valve Cover Gasket Replacement Kit

Oil leaks are very common on Audi A6 2.7T 30 valve models and are often noticed around 75,000-90,000 miles. Leaking cam chain tensioner gaskets are the most common, producing a foul burning oil smell in your interior. It makes sense from a labor standpoint to replace them during timing belt service, since timing belt dis-assembly is required for proper cam chain tensioner gasket replacement. Replacing them together will save you precious time and hundreds of $$$ of costly labor charges.
