2003 Volkswagen Passat W8 Q&A
2003 Volkswagen Passat W8 Question: Thermostat
In a labor guide I see the thermostat housing/ thermostat costs just under $500 (confirm on www.rockauto.com they are pretty good) the labor guide I have says 3.5 hours (independent of Repairpal's estimate guide so I would say there time is correct). - patrick mannion
The thermostat sits under the intake manifold on top of the engine. The thermo stat is expensive, it is electronic and uses feedback from temp sensors. They should not have to pull the engine, just the intake manifold. This web address shows a VW W12 (very similar to the W8) getting a thermostat replaced. They did not pull the engine. http://forums.vwvortex.com/showthread.php?2993477 If the car runs, try to get a second opinion from another mechanic.. good luck. - Visitor
Dealer cost is $800 in New York. Had it done at 75,000 miles. - ajbcars
I need to replace my thermostat - it is not warming up properly - how much should this cost me with labor and parts?
The mechanic told me that to replace the spark plugs that he is going to have to take out the engine. Is that true? How often do they need to be replaced and how much should they run?
