My fan exploded!
-
So yesterday I was working on replacing a bulb in my turn marker when a buddy stopped over. I threw the maker back in and took him for a quick drive. Not even 5 minutes in I heard a loud bang in the engine compartment and plastic went everywhere on the road. When I pulled over coolant was pissing everywhere from a gaping hole in my radiator. Luckily I was a block from home. So at first I thought that I may have left the tool I was using to unclip the side market in the engine bay but later that night I found it in the garage. Wtf! Now that I am researching I heard one or two other stories about this happening to e36 owners.

I can't run a clutch fan and I don't run water wetter in my e30. Just a big mishi rad and a pusher fan
-
I just run a pusher fan as well. My block was cleaned out and all my coolant parts were new when I did the engine so that has some to do with better cooling but the pusher fan does just fine to cool my car ... even at the track.
***Full disclosure, I do not have the AC condenser anymore and that may help as well.

Well Ted hooked me up with a radiator assembly and fan. I'm still nervous about putting the mechanical fan back in but I don't have time to dick around with water wetter and a new fan switch.
-
Wate wetter is $10 and pours right in with your new coolant lol. Just put some in my 328is. You don't HAVE to do the switch either.
When did you get a 328is?
-
This happened to me. Pull the belt off and check your water pump. Usually this happens when the water pump wears out and starts to spin off center and the assembly becomes unbalanced and boom! It happened to me on my 328i. You dont need the fan, just run water wetter and your fine.

I deleted my mechanical fan as well. I put in an 80C thermostat, lower temp fan switch, and water wetter. I also put in a new radiator, expansion tank, water pump, rad hoses, and an aluminum thermostat housing while I was in there. I will highly recommend running an electric fan though, the e36 temp gauge is buffered pretty significantly and you wont know you have a problem until you hit about 220F and by that point you might be too late. I have been watching my coolant temps on my ultra-gauge and they rise sharply at stop lights and managed to hit 210F when I had the car idling in the driveway for a while, so if you do the fan delete I would HIGHLY recommend installing an electric fan if you do a lot of stop and go driving.

Electric fan on either a temp switch or a manual switch in the dash works. I opted for one I can turn on and off when I feel like it
