I just had the thermostat housing replaced on my 99 Jetta VR6. It's on the right (driver's) side of the engine block. The battery and battery tray should be removed to get access to the thermostat.
To replace the thermostat on a 2001 VR6 Jetta, first ensure the engine is cool and disconnect the battery. Drain the coolant and remove the upper radiator hose from the thermostat housing. Unbolt the thermostat housing to access the thermostat, replace it with a new unit, and reassemble everything by reversing the steps. Finally, refill the coolant and check for leaks.
The 2001 Volkswagen Jetta has an inline 4 engine.
The 2001 Volkswagen Jetta has a 2.0 L base engine size.
The 2001 Volkswagen Jetta's engine produces 115 hp @ 5200 rpm.

The 2001 Volkswagen Jetta's engine produces 122 ft-lbs. @ 2600 rpm.
Follow the upper radiator hose that is going towards the block. That is where your thermostat is located so if you are facing the engine. It'll be on your right hand side just below the air intake
The 2001 VW Jetta 1.8 liter engine has and oil capacity of for quarts. The engine oil should never be overfilled.
A 2001 VW Jetta 2.0 requires 4.2 quarts of engine oil.
If your doing a lot of city driving you should get it fixed... the thermostat tells the cars computer when to turn on the fan which provides more the 50% of your engine's cooling in city driving!
