Best Thermostat for Volkswagen Phaeton
Bruce and I and my Dad replaced the thermostat, timing belt, water pump, and thermostat on the P. All went well, except that VW doesn't know how to do their job very well and got the wrong pulleys. But they did get everything else correct, and for a good price too.
Pros: good price
Cons: wrong pulleys
Vehicle:
Volkswagen Phaeton
The Mahle thermostat arrived today along with all the other bits I think I need to put the car back together. The problem is that the new one doesn't quite match the old one.
Cons: new one doesn't match
Vehicle:
Volkswagen Phaeton
Original was stuck open, replaced with new VW which now appears to be stuck closed. ????. Fortunately I have recently acquired a new OE thermostat on clearance for jollies.
Cons: stuck open, stuck closed
Vehicle:
Volkswagen Phaeton
