An engine coolant leak may develop from the expansion tank resulting in engine overheating. When a cooling system component fails the entire cooling system should be inspected. It is not uncommon to find additional component have failed or are leaking.

Overheating can cause severe engine damage. If the engine begins to overheat it is recommended to stop at the first available location and have your vehicle towed to a repair shop.

    The coolant would leak when the car sat idle in a parking lot or at home in the garage. I filled coolant and it would leak right after I drove the car. The coolant low sign in orange would show on the dashboard. Initially I though my battery fluid was low or the batter alternator was not charging my battery. But soon I found the issue. So I had to change the coolant bucket as that was leaking the coolant slowly.

    I just bought me a really nice 2001 BMW 325I, well I had it for one day and than it started to overheat. I didn't know why it was overheating, and didn't realize that the coolant is low. By the time i was able to add the coolant in it, it was too late. My car was damaged and damaged bad. Well the car broke down basically, it wouldn't start. So I had to get a tow and towed it to my mechanic. The story is BLOW GASKET, HEAD GASKET CRACKED, all because of a simple problem. So sad, repairs costly, est round 3k!!!!
