Default coolant temps with electric fans

put a cooling fan from 08 buick enclave (free gm warrenty parts)
(they fit the radiatior completely two 16 fans)
two adjustable switchs that turn on 190

today it was 78degs

my coolant temp avg was 210 sitting in the drive way,
with a/c on it was 220-225

it ran normal with the belt driven fan

so what is everyones temps with there electric fans ?

I have a single 16 inch fan and mine runs 180 degrees (180 deg thermostat) with the a/c on or off and moving. It runs about 185 with the a/c off sitting still. It runs about 190-195 with the a/c on and sitting still. These are all estimates though cause the gauge has no numbers on it.

Also, if I'm not doing "city" driving, so I don't have to stop much, I never turn it on (the switch is on my dash) and it runs about 180.

Yeah that's a little high.

I'm curious, what tires are you using with those RT wheels? What do they measure out to?

If I recall there are two different types of fans, push and pull. Please someone correct me if I am wrong but, it sounds like to me that you either have the fans installed backwards (not likely) or, it's blowing in the wrong direction.

Does that sound feasible?

Yes it is possible that it is incorrectly mounted. On the universals, they are reversible. But I don't know about stock style. But most stock styles are set up as pullers. And I'm assuming that is how it is mounted up. You may have the polarity on the fan incorrect.

Would it be worth installing electric fans on a 1996 V6??? Do they bolt right up or do you have to make extra brackets...

What else would i need to do?
