The nut pulls against plastic.

Is the electric fan working when air conditioning is turned on? My E30 struggles to stay cool in heat/traffic with the air conditioning on but I have no viscous fan, an 80/88 switch in the rad will bring the elec fan on earlier which will help your situation. The condenser rad will be having an eff...

I rebuilt the cluster last evening (replaced odo gears, cleaned everything including the contact surfaces UNDER the nuts and tightened the nuts).

Then,, it was downpouring. Didn't get the cluster back in.

Plan on putting it back together tonight.

Yeah, it should be 80c, and a rise in running temp when you stop is pretty usual - at least my 325 M20 does it. ( no electric fan ) Paul :-) In the ,, 15 or so E30's I have been involved with, I have never seen the temp climb up when coming to a stop and the engine still running. Well, I did on the...

I ran 225/50-15's on my 87is (lowered on Eibachs) and 93 ic (Front lowered with E30 M3 springs). Ran the original BBS RA's ET25.

Good day all. Been fighting an issue on an E30 I have for quite some time now and I am stumped. The car.
