1990 Golf 1.3 Driver, engine code NZ Got a coolant leak I need to fix, I know where it's coming from, but we can't afford to have the car go down if the parts stores were wrong. I need to know what kind of gasket is used between the cylinder head and the thermostat housing. The parts places are both saying that it's an o-ring, but when I look at the housing on the car, it appears to have a type of sealant on it, which would mean it's a gasket-type seal. Someone please help me out here. I don't work with the small block engines much, so a little help is appreciated.
It will be an o ring. The housing is black plastic? The housings are bad for breaking up inside around where the o ring sits. This could be the problem and not just the o ring itself.
as above,then sealanty added to bodge it up. best have a word with the dealer and get a new housing. you may also need a pair of new bolts to secure the thermostat housing to the main body. VW changed the design of the housing a few years back, the original parts had threaded inserts and the new ones use self-tapping screws. I didnt know this at the time and I had to go back to the dealer again to buy some screws!
