    Overheating Astra SXi hmmm!

    Hey there guys, shoulda probably posted this a while back but it seems to only affect me in high traffic density...
    A couple of weeks ago I noticed that my Astra SXi was heating up fairly quickly when it sat in traffic, to the point that it was nearing the red zone and I considered pulling over
    Interestingly, it cooled down fairly quickly once I got back out on the open road and above 30, but everytime she stops in traffic for more than 5 mins that temp guage just climbs & climbs!
    I've checked & the coolant level is always fine so I think it might be another issue. Right now my guess is the fan behind the grill that never seems to run.
    Anyone else got any ideas??

    Yeah mate it'll be either your fan switch or a dodgy thermostat.

    Replace the thermostat first as its the cheapest thing to do and check the wiring to the fan also.

    it wont be the thermostat as if that was gone the temp would still keep rising no matter what speed you are doing. First check the fuse. If that is ok disconnect the water temp sensor and short the wiring out, if the fan runs the sensor is knackered. If the fan does not run check the wiring to the fan and if needed replace the fan. Or come down to see me a few miles south of you one night this coming week and I will look at it for you
    Be Happy

    I had exactly same thing after changing cambelt and water pump. The air was in the system and was blocking it. Did you have water pump done recently?

    Any air in the cooling system will self-bleed out to the expansion bottle within 2-3 starts from cold to fully warm.

    Well.. mine didn't want to

    VX changed my cambelt and water pump.. I had that problem after it.. and then to fix the problem it took them 5 minutes so it was no major job to do. They said it was the air in the system.

    Back from the local garage who diagnosed a failed Radiator Fan Relay (well the first one looked at it confused, so the 2nd one diagnosed a dead fan )

    Apparently these are pretty overpriced from VX direct so I'm thinking eBay or let's see if I can get it elsewhere. Any ideas

    I've now placed a request under the "Classified" section & will probably snoop about on eBay later.
