My 325 is drinking around 1ltr of water every 300 or so miles.
Ive always thought it felt slightly underpowered since ive owned it and even more so after the water pump failed.
Their is no water in the oil and no white smoke but it has blown the expansion tank off of the radiator 3 times in the last few months since the water pump fail.
Could this be head gasket related?
How can i find out for sure?
No oil in the coolant.
The engine over heats in traffic only (left on tickover without moving)
I doubt the thermostat was replaced with the water pump.
I have no idea if the pump had a plastic impeller.
bit of an update.
The mechanic rang me yesterday and has said that he thinks that all that is wrong id the radiator and thermostat.
Hes had the plugs out and they are all fine and look the same, also the oil and water are all good.
Perhaps its not the head gasket after all...only time will tell (about 100 miles or so)
