this morning i took the car into work - a journy it doesnt usally like, but there were no signs of over heating at all!!!! the heater vents all seemed ok. i switched the engine off, and lifted the bonet to check if it was bubbling over, was ok again, yet as soon as i looked water start hissin from the top of the filler cap and just poured out!!!! i dont understand as the engine running and its all fine, yet i turn it off and it dies on me
Anyone no what i can do to save my baby??
Hey bro, let me tell you something, i know how u feel and i can say, i know the reason why it makes ur BMW overheating. I have a 1998 E36 323is, it got overheated last month, so, i change the water pump and everything seems like ok...however, after 7 days, it overheated again on the highway. The coolant sprays out everywhere under the car...then, i check the fan, the fan beside the radiator and engine is working, but, it is so slow! so, i changed a new fan. As well as a new radiator at 206 USD. When i start the car and drive, i can hear the fan's strong sound, both the front fan and the fan between engine and radiator are working together when u drive.
So, what I'm trying to say is first, hit the gas pad, if u hear any sound like "ta ta ta"... it may be the water pump is cracking down. U need to change it.
If after several days, it overheat again, trust me bro, check the fan, and radiator. Or, may be hose is leaking.
If u still getting overheated, it may be the hand gasket, the way to test it is to check u engine oil to see if it is leaking. Or if u can see the white smoke coming out from the exhaust.
Anyway, hope this helps, and enjoy ur E36!
