Hello everybody.
I am new on this forum.
Car i have: e30, 1985, 320i. European model.
Problem: Air in the coolant.
So to start with:
1. New used fan installed which works (the part with thermo thing expands so ventilator spins faster yes that thing works).
2. New Thermostat installed.
3. Hoses are allright.
Now simptoms:
1. Car is run to the operating temperature (the needle stays vertical on the middle.
2. Coolant level allright.
3. When you open coolant expansion tank (where you fill it up), liquid level scyrockets (Means Water pump works right?)
4. Radiator is warm all around (therefore few days ago i had a suspect that it was faulty as bottom half of it was cold, and top was hot, and the hose which goes from the bottom to the thermostat was cold as well).
Now it is allright.
5. Tried to unscrew the bleeder valve on the thermostat case and well liquid flows out, sometimes small ammount of air comes out.
6. Coolant starts to go thru the bleeder hose which comes out of the expansion tank when i go on the highway and hit high revs which leads to liquid splashing all over the engine block and every1 starting to beep thinking that i am on fire :D
Guesses:
1. Water pump? (perhaps?)
2. Radiator? (any way to test it other than the one i menshioned?)
3. engine head or just a top gasket for the head? (quite a determined and knowledgable mechanic said that could be the case).
So does anybody have any suggestions? I am short on budget which is the reason i am trying to find a solution with somebodies help who might know what exactly is fromm what i said.
Ask me please if you want anymore info.
P,S. You can hear water boil in the upper hose and everywhere else but the bottom hose which comes out of the rad. As well the strong hitting/clicking noise in the thermostat appears for couple of minutes until water cools down.
