Where is the thermostat for 2005 jetta gli 1.8t?
Remove all engine covers, including the one in the front of the engine. Then look behind your alternator, you’ll see a coolant pipe going in, if the car’s been running a while, it’ll be the only cold coolant hose. It goes into a housing then into the block. To remove, just undo the 2 hex bolts on the housing, and the thermostat is right there.
