I have a well loved 318i Tourer.
It recently started overheating. The cooling system didn't seem damaged in
any way, and i assumed it was the water pump - so replaced it.
This helped for a while, but then it started overheating again.
I have been advised it may be the head gasket that is causing it, but the
engine still runs as well as it did, and there is no sign of water in the
oil, although i haven't checked compression on all the cylinders yet.
Could it be caused by a blockage in the cooling system or the Thermostat
being stuck open or closed?
Surely overheating would lead to the head gasket going, and not vice
versa?
Any advice would be gratefully recieved! |

I have a 1984 325e that was over heating, I tried all the things that
have been given you, I even wired my fan to come on by switch. I found
on my car the air conditions condenser fins were all smashed flat and
the radiator was not getting any air at slow speeds or at traffic
lights. It was beyond repair, I removed it, had leak under dash anyway
so air condition did not work anyway, all is fine now. David. >> Stay informed about: 1984 BMW 318i Overheating |

I had this happen to my 318i. After checking everything under the sun I
found that it was due to an exaust valve that had gotten out of adjustment
and lost all of it's clearance. It was the #2 valve which is right beside
the temperature sensor. I didn't find it in time to avoid the valve getting
burned a little so I had to overhaul the head.
