lower degree thermostat

[rafelos1337]

I have the stock thermostat (195). I bought a 180 thermostat and i was wondering would that affect anything in the car. can i just throw it in there?
thanks.

180 is perfect. It will make the car run a little cooler. Any lower and your going to end up running rich.

t-stat hell

go no lower than a 180... i made the mistake to be the firstof my buddys to put in a 160 , and well, not a good thing, especially in a fuelie car (other buddys cars were all carb) the car ran like total *****, so i would never ever ever recommend this torture to anyone bro... good luck

i installed a 180 but since i have UD pullies it runs at 195. im going to install a 160 to see if it stays at 180....

thats strange. Are you using the stock radiator and fan? That could be why.

That is not how you fix that problem.

What radiator/fan setup do you have?

When does it do this? Stopped? Moving?

If it runs cool while moving but heats up at idle, then you have a fan issue.
If it runs hot all the time or just when moving you have a radiator issue.

180 in mine and it wirks great.
I upgraded my radiator while at it.
I agree with 90MustangGT on his reply

my car runs at about 195 with a 180 in it also. my car has the stock fan with a heavy duty clutch and the ford heavy duty cooling radiator....i think its a 2 core

edit: mine warms up to 195 and never gets much hotter unless im on the highway for a long time and its really hot outside but than it only gets to about 200 or 205

I put a 180 in mine and ever since I have some black soot in my tailpipes and have considered going back to a stocker.

If you are going to change to a different T-stat make sure you guys get a good quality one, like a Mr. Gasket. I went with an AutoZone no name t-stat, last a whole 3 months . Avoid the problems by spending a little more now and saving a whole lot later. Damn Mr. Gasket should pay me.

Curse, you and me both. I run several of them. I had a new parts store 180 and in the same week I swapped in a 180 Mr G and in the same ambient temps, the 'average' operating temps dropped almost 10*F (the Mr G being balanced is the key there).

Good stuff and for what, like 3 bucks more than a parts store stat, you cant beat it.

If that car is heating up on the highways, check to see if the radiator air deflector under the car is still intact. I had similar issue and couldn't understand what was wrong, major cooling issues every summer. I realized I didn't have the deflector down there. Popped a new one in from 50resto.com, all cooling issues have been resolved.
