[QUOTE="sgbuloh_e90, post: 271707, member: 4082"] try replacing the coolant tank cap .. sometimes the cap itself will konk out n lose pressure thus not pushign any coolant to the engine (overheating) since u changed the cap n tank . i reckon it wouldnt be the tank unless the leak from the tank is obvious . try checking the cap's underneath valve whether its still can be pushed in n out. mine gave out few month's back , was driving back home almost without coolant. imagine the idling was at 2.5k rpm ... scared the shite out of me. the valve on the cap should be able to push in n out . if it stays pushed out or in . means gone liao. if that doesnt help , just check ur radiator hoses might be small leaks that are not noticeable. hope this helps. :top: [/QUOTE]
