How did you do it? What brand/model fan did you use?

No electric fan involved, just a new dual lower temp fan switch.

Just finished the thread.

I had heard bad things about Uro parts. Any issues with the thermostat? I may have missed it but where did you get the plug and pig tails?

I heard that too, but you can different brands...even directly from BMW. Cause that's where I got the plug & pig tails from.

I connected my dual lower temp switch in "parallel" to the stock temp switch. So if the lower temp switch fails, I have the stock switch as backup. Kinda like a "raid" setup on a computer.

No issue with thermo (no sure what you are asking), but it's been replaced with a 79c thermo.

I can recall the little Renault's had that facility;the electric fan staying on for about 5 minutes after engine switch -off.

Reread the thread. How do u book them up in parallel? I thought the thermostat.has to be screwed into the coolant thing? Did u make a new hole?

My concern is still the low engine speed issue. An electric fan would pull aura in quicker win the engine is at low speed or idling.

LOL, you really need to spent MORE than 1/2hr reading the thread. All the info you need and questions you are asking are answered in the thread.

I only need to implement "step 1", found out afterwards I don't need to throw "idle" into the mix.

Now back to the Aux fan. Wiring the main wire at the fuse panel (Circuit #8) to battery does not let the fan run after the key is shut off. This wire must power another system somewhere first (where the temperature is read) and the power to the fan is controlled there. The wiring diagram shows it goes to a temp switch at the AC system by left headlight, but disconnecting that does not shut fan down.

I live in the Palm Springs, CA area where the summers hit 115F every year. My solution to engine heat the last 10 years has been raising the hood after parking in my garage. This has worked out great. Little if any plastic parts degradation. I even had a battery last 2 years beyond its warranty date.

This trick doesn't work on my M104- I ordered a cool harness and it just caused my temp gauge to read wrong and the car hard started from cold.

Once I got to AZ (PHX exactly) it wasn't needed. Car was fine and didn't run any hotter than usual (100C) even idling in traffic at 122 deg- no joke.

Frankly, between this car and my 2002 S10 truck I thought the Benz would have problems with heat- all over the boards everyone complains. My Chevy was the one that had a hard time with this temps....

..........................Then again C36 cooling system is 100% everything works
