What to replace while changing the VW Beetle timing belt on the 1.9 TDI ALH engine.

VW Beetle Timing Belt Replacement Diagram 1.9 TDI
IMAGE DESCRIPTION Apart from the timing belt the 1.9L ALH Beetle TDI 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 two small fixed idler bearing, one centrally located on the timing belt system and the other is on the top side of the timing belt system. Fourth is the timing belt tensioner which provides variable spring loaded tension to the timing belt. Fifth is the large idler bearing centrally located on the timing belt system. All of these components work in sync with each other to guide and tension the timing belt.

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 Beetle TDI timing belt isn't enough. Why? Around the timing belt service interval (90-100,000 miles), due to age the integrity of the tensioner(s), 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.

Tensioner

Why replace your VW Beetle timing belt tensioner 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 (90,000 - 100,000 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 and accelerates it's life span, often resulting in premature failure.

Water Pump

Why replace your VW Beetle 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 a VW water pump can weaken and is the primary reason why a water pump eventually fails.

Thermostat

Why replace your VW Beetle thermostat during timing belt service? 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.

    Preassembled BASE kit comes directly from our partner Schaeffler who has been manufacturing timing belt components under the OFFICIAL O.E. INA brand for decades. These kits include the same manufactured brand of timing belt, tensioners, and idlers as supplied to VAG.

    Please Note: When originally released, the factory recommended timing belt interval for ALH TDI VW Beetle with was 40,000 miles for automatic transmissions and 60,000 miles for manual transmissions. However, in 2003 VAG raised the timing belt interval to 100,000 miles. This was done because of improvements made to the timing belt idler bearing (an increased ID from 47mm to a 60mm), and a stronger timing belt (carbon aramid material). This BASE kit contains Official O.E. factory specified improved timing belt and tensioners for the 100,000 mile change interval.
