91 e34 2 litre still over heating
Hi
I just changed the water pump and belt, took it for a quick spin and it soon went almost into the red...i just went around the block and got home. I wasnt in stood traffic, and the fan was spinning, but it soon went over the half way mark. Only thing i can think of is the thermostat thingy...or am i missing something else? thanks |

I'll bet you didn't bleed it right. With a cold engine, remove the radiator cap and open the bleed screw. Have the heater full on. Run the engine until it gets warm, topping up as needed. When it gets warm put the cap back on and shut the bleed screw. Leave it until the temp gauge is in the middle then open the bleed screw whilst revving the engine lightly. Close the bleed screw when there are no more air bubbles. Let it cool over night then top up the coolant if needed.

I did that, kept topping up until it got warm, had it running idle until the gauge hit midway. > > Let it cool over night then top up the coolant if needed. > > Works for me. ok will try that cheers....never bled a radiator as such. thanks > > > -- > Who needs a life when you've got Unix? :-) > Email: , John G.Burns B.Eng, Bonny Scotland > Web : http://www.unixnerd.demon.co.uk - The Ultimate BMW Homepage! > Need Sun or HP Unix kit? http://www.unixnerd.demon.co.uk/unix.html > www.Strathspey.co.uk - Quality Binoculars at a Sensible price |

The bleed screw is on top of the thermostat housing IIRC. FloydR |

I totally did that right...stil the same, i changed the thermostat...same problem, points towards the red v quickly after a spin around the block....i took of teh radiator and flushed it both ways......after a while it came clean, but when put back on, like a hour a ago, it was soon over half on the gauge going towrds red (never let it get into the red though) SO it must be the radiator then....if i put a water hose in the rubber from the top of the engine, it would come out at the botom after going through the block, so thats ok. its just not circualting, the radiator is always stone cold on the metal fins.... Hope someone else can offer advice....thanks > > > -- > Who needs a life when you've got Unix? :-) > Email: , John G.Burns B.Eng, Bonny Scotland > Web : http://www.unixnerd.demon.co.uk - The Ultimate BMW Homepage! > Need Sun or HP Unix kit? http://www.unixnerd.demon.co.uk/unix.html > www.Strathspey.co.uk - Quality Binoculars at a Sensible price |
