    Hi

    Driving a ’96 Opel Vectra 1.7 TD
    Keeps overheating in traffic, no problem on the open road
    Stopped the other day after being in traffic and water came overflowing out of the water tank, let it cool down and topped it up again before driving away
    The radiator looks to be ok
    Any ideas as to what the problem might be and how it would be fixed??

    Thanks

    The problem here in your case OP could be the radiator fan not kicking in. Check (carefully), that the radiator fan is cutting in and out. You'll have to park the car and observe the fan for a while with the engine running. Get back to us if you can state whether the fan is working or not. If it isn't, then we can look at the options/root cause from there forward. if it is, then we can look at what else might be the cause of the problem...

    Thermostat stuck closed? Fan not working? Those are the first two things i'd look at.

    Firstly if you know the car is overheating, don't drive it if at all possible. As others have suggested check the radiator fan is kicking in, it sounds like its not....

    If the fan is not working, it could be a fuse, thermal switch, relay or the fan its self. Anyone who knows their way around a car would be able to by-pass the thermal switch and test the fan etc....

    Can you see the temp dial rise on the dash?

    hi again

    thanks for the help, yes I can see the needle on the dash rising if im going through slow traffic. Fortunately I don't get stuck in traffic for long en route to work

    I took it out tonight into traffic, the needle went up again and I pulled up and popped the bonnet. The fan is not kicking in, will this be a big (ie expensive) job ???

    thanks

    I *will be* expensive job if you don't get it sorted out soon. You can warp or crack your cylinder head when it overheats, or at least fry the head gasket.

    Can't see the fan being expensive to repair. You could try to locate the connector for the cooling fan, unplug it and feed power to it straight from battery to see if the fan unit itself is ok. Then just troubleshoot the problem from there. Maybe get a second hand fan from breakers' if the fan itself is faulty.
