engine overheating
Hi All
I have a 04 plate e85 2.2 z4 . for a number of reasons the car has been stored in a dry garage. Only coming out once in January this year for its MOT which it passed with no problems. I am now in a position to put it back on the road which I have from the 1st of September. Eagerly I took it for a spin on the 1st only to find after approx 8 miles the engine completely overheated with the temp gauge in the red. I left the engine to cool down and checked the engine coolant level expecting the level to be low in the radiator, suprisingly it was full, so I am not sure as to what is causing the engine to overheat. Any ideas anyone. Many thanks Rob

Could be a blocked rad or a non functional water pump

Hi matey
If your water pump is original it could be on the way out- any unusual rumbling or rattling from front of engine?

Possibly an airlock?
Was it really hot? Sounds silly, but was it a sensor issue or was the engine actually that hot?
And thinking more abstractly, are the brakes ok?
Binding brakes 'could' make the engine work harder, but I'd be surprised if you didn't feel it, plus see a fair amount of smoke from the wheels.

Method I'd use is get the front of the car up on ramps or jacked-
Take the front splash cover off the engine, next to the water fill point there is a hose that leads from the radiator to the engine, on top of that is a bleed screw- undo that while the engine is running to release any air in the system

And to amalgamate Stuart's two replies so far, if you don't get water flowing past, or out of, that bleed screw, then you could have a water pump failure.bigwinn wrote: ↑Fri Sep 03, 2021 2:07 pmMethod I'd use is get the front of the car up on ramps or jacked-

Adding another thing to the list, if the engine does get hot, is the radiator hot as well?
Could be the thermostat stuck closed?

100% on this
I'd be looking to find an air lock, faulty thermostat or water pump in the process
Assume belts are all OK? No warning lights?
Where you based Robert?

I think I will go down the road of an airlock first, and then take it from there . Iam based in Burry Port which is in West Wales

These engines don't take kindly to overheating - I'd expect head gasket issues before too much longer.....

Well while you're running it to try to clear an airlock, you can hopefully check out whether the pump is actually circulating the coolant.
And after a few minutes, if the block is getting hot, check the radiator too.
That way, after running it for just a few minutes, you should be able to do most of the diagnosis we've thought of so far.
Yup, West Wales................... you probably have some of our colonial cousins who are closer to you than I am in Norfolk.

I would certainly try bleeding the system first, check rad gets hot and thermostat opens by monitoring temp on live data diagnostics if you have that capability. Too bad I am in East Wales, Newport or I would have a look and plug it in to diagnostics for you.
