7M-GTE Radiator Fan

Yeah, you should never run a mechanical fan without a clutch, factory or otherwise. You're lucky it didn't come through your hood.

Yeah, after doing some more research I realized going back to stock is going to be more expensive than I anticipated. If I'm going to spend that much, I guess I might as well get a good quality after market one. Plus I wasn't really too excited about the large fan shroud taking up space...

How do those fan controllers work exactly? Do they measure air temp or coolant temp? Because the sensor that's on my car now for the fan is pressed right up against the radiator so it just measures air temp.

I like the flex-a-lites, again because of the flexing blades, but I also found this one and haven't quite made of my mind yet:

Doesn't seem like to bad of a deal since it includes a new aluminum radiator as well. Quality is my only worry there...

I've also seen some Godspeed radiators that seem to be a pretty good deal. Any input on those?

This is what I got

This is what I use to control them uses coolant temp. To turn on/off it been 100+ degrees by me and my car is running fine same temp and everything.

Fan shroud.... taking up space....?? What else you going to do there anyway? Keep a cooler full of beer?

Going back to stock should be VERY inexpensive if you source a used fan, shroud and clutch (rebuild the clutch yourself for about $30). From the sound of it it'll be cheaper than fixing what you have and will be cheaper than a lightweight, low drag mechanical setup.

The fan needs to be driven based on coolant temp. It should turn on at around 190?F. It needs to be controlled with a relay off of the alternator output too. Do NOT rely on any stock wiring to control the fan or power it! Don't forget to add a proper size fuse to the power supply line as close to the source as possible.

I guess "taking up space" was a poor choice of words. I just meant that the factory fan shroud makes it look more cluttered I guess. The electric fans just make it look more cleaned up since they're slimmer and less noticeable. But I'll take reliability over appearance, and it's not like there are going to be that many people looking under my hood anyway.

And a cooler under the hood? How absurd...

The ice would never last in those temperatures...

I expected going back to factory to be inexpensive, but after I shopped around for parts for a bit I was wrong. I've been having a hard time locating everything, particularly in decent used condition, but I'm going to keep searching and maybe I'll have more luck.

Also, can anybody tell me what the factory fan size is?

Do not buy a clutch from autozone. I got a new one from there a while back and 2 weeks later it locked up returned it for another one a week later that one would make a loud sound over 3k rpms like metal to metal
