What to replace while changing the VW Golf timing belt on the 1.9 TDI BEW engine.

Apart from the timing belt the 1.9L BEW Golf TDI engine's timing belt system consists of 3 serviceable timing belt components. One is the water pump that is driven by the timing belt. Second is one small fixed idler bearings, located on the mid to lower area of the timing belt system. Third is the timing belt tensioner which is centrally located on the timing belt system and provides variable spring loaded tension to 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 BEW Golf TDI timing belt isn't enough. Why? Around the timing belt service interval (80,000 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 Golf 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 (80,000 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 Golf 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 VW water pump can weaken and is the primary reason why a water pump eventually fails.

Thermostat

Why replace your VW Golf 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.
