Yup. Is there someone who is raising the rear? Actually, it would seem to me that raising the rear makes more sense, but I've always raised the front. How do you get your engine to overheat, though? <grin> I can't get mine warm enough. I just checked the archives of the vanagon list and found many reference to different ways to bleed the cooling system, and they all say raise the front higher than the rear. One even says explicitly "raise the front 18" higher than the rear not the other way around!".

I never got 2 gallons in mine. Of course, the bleeding thing is weird to me anway. If I open my expansion tank while the engine is running, coolant runs all over the ground, so how can one bleed it? Even revving it really high, it runs all over the ground. Maybe I don't have the front raised high enough? I like the coke bottle idea, but the same goes there. If I open the bleed screw at the front, coolant just pours onto the ground ( and would fill the coke bottle in a hurry.)

> Let's clarify this FAQ, please.--

Indeed, the more information we can gather on bleeding, the better. Does anyone else raise the rear, and can anyone else say why one should/shouldn't do so? I can think of some reasons, but I have to go work on my intake air hose which has a BIG crack in it. No wonder this thing always runs a little rough.
