Alright M30 guys, I'm sick of this overheating issue....

[george graves]

I only run a fan at the drive thru....Normal M30 operation is the same as a m20...


Something else is a miss...

[MrK]

I think climate and traffic have a lot to do with a problem such as this. I am on the Mediterranean, and I just went thru 1:40 of first-gear traffic this morning to get to work. It takes me 10 minutes to get there if there were no cars. My car went to three-quarters hot, and that's with the a/c fan on all the time.

Edit: For clarification, the a/c FAN was on, not the a/c. I don't have it connected yet. God knows what will happen with my temps once it's connected.

So, is this the nature of the beast for you? Is this just....the way it is?

Relevence of this statement? Sorry me no speak good english. Bleaze tranzlate.

lol, I meant that maybe this is just the way it is for M30 E30's. Maybe they just run hot in the summer. 3/4 is not out of the ordinary for 80 degree heat in traffic.

Either that, or you have air in your system as well.

[MrK]

Oh I see what you mean.

Well from personal experience, I have had my m20 in similar conditions, and it never ever got beyond the halfway point, so I'm inclined to try a stronger fan/bleed further before I proclaim that "this is how it is."

Besides, I'm JUST on the threshold of having a stable cooling system. It takes a full hour and a half in standstill traffic for the car to overheat. I assume that a fan that is even SLIGHTLY better would do the trick!

[E30/M30]

How about trying an E32 a/c fan ? Big fan for not too much $$$.

[Garageaholic]

Sounds like an idea. Anybody have any other ideas for fans??

That was gonna be my next step. I'll keep y'all updated on results.

Works fine on my 335 but it's probobly not as hot here in the UK as your country.

This is definitely not normal, I've owned several M30 5 series and an S38. They all stay dead on at half way in any kind of heat unless the fan clutch dies. It's easy to tell - there are no stupid tricks, if it's working, you'll hear a loud ass howl from the engine if you rev it even a bit.

Here is a picture of the possible culprit

Here is an attached picture of the hose going from my T-stat to my heater core. It goes up and then down again over my brake booster. I think that this is where my bubble is. I'm going to see if i can re-route the hose from underneath. I know that will help immensely to get rid of the air bubble.
The only thing that confuses me is that I still have hot heat blowing in the car...


Opinions?

I'm sure all those m30 5 series cars you owned had SPACE FOR AN ENGINE FAN.:D

My e30 doesn't. We are discussing maintaining engine temp with only the electric acc fan.

Bump

MrK, i like your avatar. noice

[euroshark]

Whoa, we need to get E30M30 stickers!!!

And I think even though you may have an air bubble, I wouldn't count on it being in a hose towards the firewall. Definitely try your best to get the bubbles out, but the reality is you have an M30 with a turbo!!! It's gonna run warm!! lol

Good luck man, I hope you get it worked out.
