Cooling - What do we really need?

i think he's making a point, as in, thats a 2.3l and its rad is smaller than ours, so there more to the cooling system than just having a big radiator?

Also, to my eyes, it doesn't seem considerably thicker than a 4efte stock rad...

thats bullshit!

its cause, going downhill on an engine break the engine is turning due to the power of the rotational force of the wheels.. ie there is no strain on the engine, if u look @ a wideband u will also notice that ur in the dead zone as far as af goes.. something between 17af to 20af..

NO this wont harm ur engine duh.. the engine cools faster as its flowing freely, just throwing in enough petrol & spark just to keep it going.. thus everything cools down quicker ;)

A lot of the stuff in this thread LOL.

Your right, but what actually happens is the engine "turns off" when rolling down a big hill at more than 1600 IIRC RPMS turn your engine off, and back on it wont harm it as there won't be a difference. (don't turn 2 far and get the steering lock stuck on, and don't dip the clutch)

Your AFR should be 20.8 as theres no fuel been used at all, (although there might be some left in the exhaust)

Also, as for jacking the rear of the bonnet. I reckon it will aid cooling, the pressure diffence which (can't remember the users name) mention would be correct, but if you jack the rear of the bonnet then the pressure will be lowered creating a higher rate of flow. Heat rises, so it will help when stood as well, when moving at speed the air going over the rear of the bonnet will create a vacuum to further draw more air out.

My other cars an Evo 6, the vent on the bonnet is directly above the exhaust manifold, you can feel/see heat rising from this, so it shows a vent works.

Can't see them doing much for your average barried corsa though ;)
