E 46 overheating ... again.
I was almost home today when the "low coolant" light came on... by the time I got it in the garage, it was steaming from under the hood and, indeed, low on coolant. I topped it off and took it out for a short ride around the block(s) and it was doing the same when I got back home. Since my earlier problem with the cooling system ( leakng expansion tank), I've had a SMALL leak/ loss of coolant, but have required only an occosional topping off, maybe 4-6 oz. per 1000 miles. When I took my first look under the hood , I could see steam coming out of what I would call the upper radiator hose. Is this because this is the (by design) weak link or is this hose failing under pressure? I question the BMW method of making these connections. <OH, THE HERESY!!!> While the clips that secure these hoses are esy to install, are they as tight as ordinary hose clamps? What does the comunity think I should check first?
