    Cooling Fan Switch

    A little bit of advice needed, im wanting to wire in a manual cut in for the cooling fan on ma coupe turbo. Especially for the warmer weather here now. Anyone know how easy this is?
    Will it interfere with the automatice cut in?

    Ive fitted a cool running thermostat from regal today, cant honestly see the benefit, it warms up quick but then it doesnt run any cooler, temp guage is still at 80degrees. I was thinkin a manual cut in would help in the traffic/round about town driving.

    Has anyone done this on their cars?

    Any insight would be muchly apprieciated!!!

    There really is no point. The cooler thermostat cuts the fan in sooner, but the engine will still run at similar temps. I have known mine old GSi to hit near as dammit 100deg when sat in traffic in hot weather. No probs once moving again !

    90degs is fine in all honesty. Its not until you get much in or around 100degs that i would start to consider additional cooling.

    You don't need additional cooling.......
    Unless you are flat out and pushing it hard then slam into full on grid lock.... Then you MAY have a problem......
    Seriously, we have 42+deg days and traffic and i haven't heard of a single astra overheating, even with a/c on the whole time

    Press the aircon button in traffic and the fans will cut in to get air through the condenser, so this will draw air through the rad at the same time.

    A cooler running stat will only open at lower temperature, it won't force the cooling fan to come on any earlier.

    I was of the opinion that cars sold to countries with warmer climates were fitted with a cooler running thermostat in the factory, thats why they are so readily available, as they are basically an Opel off the shelf part

    Nope, not that i'm aware of..... it's the same..... My 2.2L heats up pretty quick, even on COLD mornings like sub 5deg (that's cold here) it's still at op temp within about 5 mins of driving with the heater on....! In traffic it will go to the middle of the guage before the fans turn on (which is pretty darn hot).... I've driven it in 43deg heat - it's been a little slower, but not badly.... traffic + 43deg = fan on 90% of the time in traffic, i had the a/c on full as well.... that's pretty impressive for any car...... After you stop and open the bonnet though, wow, there's a LOT LOT LOT of heat under that!! lol
