coolant on top of overflow tank
Does anyone else ever find coolant all over the top of the tank after a long drive?
My 3.0 does this often. I'll clean it all up, then after the next long drive it'll happen again. I don't think the tank is overflowing, as the coolant level is normal when it is stopped. I tried revving the engine while watching the tank, and I did not see any bubbles come up. Not showing any other signs of a blown headgasket.
All I can think of is that the coolant may be sloshing around on bumps and the cap just doesn't seal well enough. It's not supposed to be airtight though, is it?
