Put a stock fan and clutch back on. No electric fan will ever pull cfms like a stocker. Of course you'll get people in here that swear by them and will argue.

BTW, back in the day I ran dual flex-a-lites. I did the conversion in the winter time so the car ran ok. Once spring time came around and temps started going above 80* the car would start to run hot. I put the stock fan&clutch back on and problem went away.

That and make sure all the shrouds/underbody paneling is in place. They make a HUGE difference in the cooling efficiency, directing the air through the radiator rather than just wherever it may want to go.

i ran my 87 turbo with no shroud for 8 months through spring and summer
never overheated

i dont like the idea of the electric fans...especually since our cars are prone to overheating
my thoughts are how would you know if your electric fan goes out...cruising along and that minute you dont look at the temp gauge...boom motor is done
plus when the mechanical fan is in full field it sounds cool lol

Doesn't change the fact that it makes a big difference to the cooling capacity. I had mine without the shroud for a period of time as well and didn't have issues, but did notice it running much cooler (almost 10*F in the same conditions) when I put it back together properly. It's always better to have it on.

So you couldn't figure out how to make it work, so no one else has a chance? LOL

No it's just smarter and easier to leave the stock fan clutch. There is no real gain from electrics.

You can use something like a tauras fan that flows huge amounts of air. Will need to be oem and big. All the little tiny e fans are not going to come close and temps are going to rise.

Radiator shouldn't be used for a band aid due to fans not pulling enough air. Get the coolant hot enough and it's not going to matter anyways.

For the record, the car is designed to run about 210 degrees. The thermostat opens at 192. That isn't the temp it maintains, that is the minimum it maintains.
