The diesel engines equipped in 2000 Volkswagens use a liquid coolant system found on all late model gasoline engines. The coolant passes through the radiator then goes into the engine to prevent it from overheating. If you have air trapped in the coolant system, the diesel engine fails to cool the engine properly. If this happens, you need to remove the air from the coolant system of your 2000 VW diesel.
Instructions
- 1
Open the radiator cap located on the top of the radiator by turning it counterclockwise. This relieves pressure on the Volkswagen's coolant system.
2Crank the Volkswagen's engine, shift the transmission into neutral and set the parking brake.
3Turn the heater on to full heat. Turn on the defrost and set the blower on the highest setting. This circulates coolant through the engine and through the heater core.
4Run the engine for five minutes. As the coolant flows through the coolant system, it purges the air out of the radiator.
5Stop the engine and check the fluid levels in the radiator. Often, when you purge air, you must add a small amount of fluid to top off the radiator. If necessary, top off the radiator with a 50/50 mix of coolant and distilled water then repeat Steps 2 through 4.
6Place the cap back on the radiator.
