Hi guys, i changed my water pump and i cant get the heater to work.
I have a 1997 Bmw 318i e36 with a M43B18 engine.
It did run rather low on water when the old pump was leaking and i imagine it drained the heater core, since then i have bled the heater hoses, bled the radiator and ran the car with the radiator cap off (as the mechanic said) , none of this has given me back my heater, it was working fine before :-(
Any help or suggestions greatly appreciated, its winter now and this lady doesn't like the cold, brrrrr.
Thank you lots for reading.
