Have a bmw 316 it over heats when stopped after bout ten mins with the engine still runnin,, also the fans r blowin cold

If your losing coolant water pump may be leaking, not enough coolant will make it overheat. If not that, thermostat may be bad stuck open or shut. Hope this helps

i see answers to other questions here except the question asked about no heat in a 325 xi 2001 blower works great fluid is full no leaks,fuses are fine,get a lil heat while at a stand still but as soon as you drive cold air only temp on max 91, engine temp right in the middle takes about 8 mins for temp gauge to reach the middle can anyone help with this..PLEASE !!!!!!

The refrigerant level is low or the pressure switch is bad.

You can get Timing chain for all your car models especially for your BMW 316 Diesel Engine car at

usually when the heat is turned on and temp goes down it means you probably have a bad head gasket leading to the high temp the only way to do this is to have an compression test to see if your heads are leaking.of you did radiator you also did thermostat,and make sure your engine cooling fans are workingto check this just look at your engine while parked let the motor warm up and see if they go on maybe the auto switch on cooling fans are no good

get it diagnosed correctly before you end up buring up the catalytic converters.

did the fan quit blowin or did the cold air stop blowin?

Check exhaust, sounds like a small head gasket leak.

sounds like engine management chip fault,may be worth getting checked at dealers as will show on diagnostic machines hope this helps andy
