coolant where it shouldnt be possible heating issue?

[mr.vang]

typically it would overheat between 1/2 and 3/4 but usually just goes away while im highway driving. then a time came where every stoplight i came to the car would dangerously overheat.

sound like clutch fan

if you do tackle this hose cleanup/delete I would suggest for the hose that runs from the ICV to the intake boot that you put a piece of hard plastic connector in the middle of the hose to prevent it from collapsing, you can find the straight connectors in the HELP! parts in any auto store.

it's been replaced with new parts. also did pump, and thermo. my aux fan turns on when i hit the a/c button but dont see it turn on when temp gets hot? possible coolant temp sensor?

Could this leak from that plastic pipe be the reason why I overheat?

Ray - I just did the mess under the intake and had a small leak there. I drained the block too in order to clear what I think was an improperly bled engine - as I think I had a huge air pocket in there. I had the same symptoms that you did after switching radiators and changing the clutch fan.

How I fixed this: When I finally went to fill the radiator after installing all the coolant stuff I preloaded the upper radiator hose to the thermostat. Then I filled the coolant expansion tank to the COLD mark with the bleed screw out. I let it sit overnight and it fell three lines below that mark as it forced the air out of the block and finally leveled out. I then filled it back to the COLD mark. I put the heater on full and turned the fan to full as well so when I started the car it sucked the coolant pretty good out of the expansion tank. I put about a full litre into it while the car was rnnning.... when the thermostat opened at temp I revved the engine and got a pretty steady stream of coolant from the bleed screw, so I topped her off and buttoned her up. Car stays rock steady now at one tick below half on the temp gauge.

PM if you need some help ... I know a number of folks were there for me when I did mine.

Thanks gerta, I will try this method. I will try as u say, I will also do the "mess under than intake" will let u guys no how it goes!

[Gerta]

No problem. It might not be the "best way" but it worked for me ... You may find all the hoses need to be replaced and then your choices are OEM, parts store, or silicone. I used a combination of silicone and OEM. www.hiperformancestore.com is where I got my silicone kit for the M42.

Buttchug and a number of others are resident experts IMO ... you should ask their input as well.

aux only turn on for a/c, so it should be off when the a/c is off.

I may be wrong but I read somewhere that the aux will turn on after a certain temp? Again sorry for the noob questions but its my first 318 I'm putting in work.

And gerta, I think ill be going oem for the plastic coolant thingy. And source cheap rubber hoses for the rest. College kid on budget trying to make it big in the e30 world. So far love it.

Randy ... wise move on the elbow those things leak. Mine was broken inside the block. You may find because of the different bends that the OEM work best. If you do order OEM, you should look up www.blunttech.com as a source. Quick shipping and good customer service. I know a lot of the R3V members do a lot of business with him (myself included).
