    'Normal' running temperature

    Hi guys,
    I have a 2.0 SRi with X20XEV engine, and like all Astra's it doesn't like it after sitting in traffic, and thanks to heat soak it loses some of its 'go' for 1/2 mile or so, until the temp comes back down.

    1) Is there anything you can do to stop this becoming such a factor?

    2) What is the 'normal' operating temperature for the engine? Mine hovers between 85-90, but goes up to 94/95 if stuck in heavy traffic in warm weather. (best performance appears to be when engine is 85-87).

    3) In 18 months of driving I have never heard the fan kick in - is it faulty or does it need to be much hotter for that? (never seen temp gauge go over 95)

    4) Would a cool running thermostat make much of a difference? (What temp is 'cool'?)

    Thanks,
    Tim

    o) have you got a cone filter on. as they dont help at all,
    1)you could remove the bonnet felt. see if that help cool the engine
    2)temp is ok that's normal. although not all gauges are the same. you could fit one from the scrap yard and it might read different.
    3)leave the engine running whilst you wash the car and it should come on whilst stationery after about 15min or soo.
    4)no such thing. apart from removeing it completely. not recomend.
    although some thermostas open earlyer than other's but once there warm/open youl have the same heat. untill the fan kick's in.


    you could also wire in a manual overide swith for the cooling fan. so you can control it from the cabin. dont ask how never tried it on a astra. worked well on a mk1 fiesta i had years ago

    The temperature is not something to be worried about. If it goes into the red, then worry.

    Cool 'stats are available for ablut £25 from courtenay or regal IIRC, but you will regret it in the winter!

    The only thing to do if this is really bugging you is to fit a fan overrider switch, but do not have it running all the time.

    .


    they just open sooner. different wax inside that's all. with a 2.0 thermostat it probably open's sooner then say a 1.4 anyway.

    could alway wrap the engine in "bakofoil"

    ok, thanks guys. I'll just leave it, and deal with the lack of acceleration after sitting in traffic then

    you should be ok with panel filter.

    maybe your thermostat is not fully opening. hence the extra heat. just a guess.
