Hello,

I need a good step-by-step on how to change my Thermostat for my 2003 Jetta GL 1.8T

I've just replaced my battery and my Coolant Temp sensor, but I know the thermostat is a bit more complicated because of the replacement.

The car is overheating pretty severely, and I could really use your help asap.

Thanks,
Miss Pheonix

Could be thermostat or:

do your fans run when the car gets hot? If no, find out why.

has you water pump ever been replaced? Should have been replaced with timing belt before 100k miles. Was it? Impellers break on these regularly.

I know this doesn't help with the t-stat swap but don't be discouraged if that doesn't fix your hot problem.

Good luck Miss. P.
