hey when i got my jeep it had the 190-199degree thermostat in it and it would get to about 210 all the time and when i would turn the motor off go inside for like 10-20 mins and come out it would start up and almost sound like it wasn't running on all 6 cyliders or miss firing and popping and stuff and i noticed the temp was over 210. so i changed it to a 180-189 degree thermostat and it runs a about 190degrees and when i'm in a drive through or at a stop light it goes right back up to 210 and does the same thing when i turn it off that it did before? i mean it even have a heavy duty radiator. should i go to an even cooler thermostat or what should i do? thanks, dustin

flush the coolant, make sure your shroud is still intact for the fan, and i would pressure wash the radiator, lots of bugs and stuff will get stuck in there and make it harder to cool things down.

ok , the thermostat only controls minimum temperature , it does absolutely nothing and i mean nothing for maximum temperature .

does your electric fan work ? put on the ac and see if you fan turns on . when was the last time you changed coolant . does your viscous clutch fan work ? shrouds missing ? lights in front of the rad ?

could be all plugged up with scale , if i remember right 1/4" of scale is = 3" of iron for thermal conductivity . basically if the inside of the rad and engine are covered in build up then it wont cool well .

belt tension correct ? hows the water pump ?

thanks for the help. i have a winch up from u think that might be causing it? i mean all the fans and stuff work and the radiator is barely a year old. it sucks when i'm on trails and we stop for a break and the jeep starts running shitty until it cools down. anything u sugust to help this promblem?

as long as the winch isnt 1/3 the way up the grille i dont think it would bother it. If you have been trail driving I would just suggest trying to clean up your engine compartment, including all parts that get heated (block, manifold, intake, and radiator). most of the time with riding trails youll hit a puddle and mud particles will settle in the fins of your radiator, no biggie, just pressure wash the radiator after you ride trails. If that all doesn't work stop at your local parts shop and pick up a bottle of Water Wetter.

high performance aftermarket fan perhaps , get a tranny cooler if you have an automatic .

high flow thermostat housing . there is actually a write up on this site on cooling the jeep down .

cowl induction hood or cut outs in the hood . http://www.quadratec.com/products/55023_003_T.htm
