What temperature does your e30 run at?

[kangman]

My temperature gauge goes a quarter of the way on the clock is that normal? before the conversion, (1.6) the needle use to go half way


, Just curious

Mine is bang in the middle, some people seem to run at 1/4. I've seen various explanations from different thermostats to the gauge being very sensitive in the middle of the scale.

My E30 usually runs at just above quarter, always has done and never had issues.

[G-Bear]

Mine usually just under halfway on the gauge.

[jimbom30cab]

Just under half way on the 325

About eleven o clock

I need to bleed mine correctly so at the moment, depending on the heater fan speed and traffic...just under 1/4 to just above 1/3. Really should sort the bleeding properly.

1/4 to 1/2

Mines similar to yours

I think i may need to bleed mine, is it when you raise the front end?

[FinalD]

Yeah, you need the nose properly in the air ideally do it on a steep hill to ensure it gets the air out. Mine *could* be related to the viscous unit as I don't know how good/bad it is, I could do with changing it I suppose.

Just a couple of needle widths below half (unless it's a hot day and I'm in traffic).

4 pots and 6 pots use different rated thermostats, so run at different temperatures. 4 pots run the hottest, with the gauge in the middle, and 6 pots run a little cooler, at part way between the quarter and centre marks.

I bled my M20 yesterday.

Raised the front up. Had the blowers on full, at the hottest temp on the dial.

Started up the engine, kept the revs at about 2.5K and opened the 8mm bleed valve on top of the thermostat housing until coolant started to come out.

I repeated this process several times until just coolant came out when opening up the valve.

The vents inside your car should have nice toasty air coming out once its fully bled.

Mine use to run over half and in traffic use to go over 3/4. But i found the cause. It was the fan. The thermostat part of the fan. Now been replaced and sits around the halfway mark or just under

Mine's been funny like that recently. When I fitted the engine it was bang on the half-mark. Gave it to a garage to replace one water pipe, and since then it sits over half and sometimes goes all bouncy towards the red before settling down again. I've bled the hell out of it but it still does it at odd moments when driving

Probably has the wrong stat fitted. Should be 80 degrees in a 325i.

Maybe they disturbed the connector to the sensor when they changed the pipe? Might cause the bouncing.

Brass nut on the back of the instrument cluster. It's all in the wiki!!

As stated the 4 pots need a "88" deg C thermostat while the 6 pots take the "80" deg C. thermostat....should be stamped on the metal.

My 318i M40 used to run too cool...I saw that a previous owner had the 80 deg thermo fitted.

For bleeding my 4 pot I've always used the method in the restoration bible, it seems to work for me every time without the need to raise the front.
My guage read a quarter until I fitted a genuine thermostat and has read just below halfway since.

[Alex]

All 4 pots ive owned with a working thermostat have sat bang on in the middle

all the 6 pots ive had run slightly under half

[Ajsingh]

My old 2.7 and current 2.5 sit between the 1/4 and 1/2 mark. Never no issues.

Apprently being dead on halfway and just before is only a few degrees differance
