how do i fit the temp sender?do i need to take the housing apart?if so do i need new seals?is this job difficult?

Temp gauge sender unit should simply unscrew from the housing.......screw new one in.
Can't remember if its an o ring or washer, suspect o ring. Either way, ideally, you should replace.......however if its not damaged you'll probably get away with re-using.

i'll go and try it now,but the new gauge looks to big.brb.

[eyeletboy]

the gauge is to big!!ihad it from vw so the part number must be right?the connector is the same but the body of the part is to big.

[richandhazel]

Sure you got the right one? Temp gauge one is in the housing at the opposite end to the timing belt, if memory serves me correct.

hold on i'll be back.
