I'm trying to get used to this replying bit, it seems like i replied to myself? Thanks again ianda12, I WISH, i tried that, different thread sizes. Hi Ming, i investigated that possibility by slacking off a joint to the pump whilst the motor was running and got myself a face full of hot fluid. Maybe i should explain, i bought the car in the UK and it had been converted LHD, basically ok but not happy on straight roads,checked for over adjustment and found the rack was bent (i found another problem but will tell another time, scary!!)so hence the beginning of my worries.I have found couple of pipes from the system heading off behind the radiator, will have to take the front off unless someone can tell me im wasting my time.If one of you gets this reply can you make sure the other did.
