over heating problem
Hey guys so I just purchased my first ever 4x4 jeep grand Cherokee Laredo has the v8, anyway it drives fine and everything but everytiime I go up a steep hill the temperature climbs to about 230 haven't seen it go past that yet, I bought it to go wheeling but i'm worried it's gonna start overheating once I start putting the pedal to the metal in the mud holes; Has an electrical fan, wondering if the fan is too small or something, I just replaced the thermostat thinking that was bad but the problem has persisted any ideas? bad whater pump maybe? I have no experience whatsoever with v8's so any help will be appreciated

Me personally id go back stock local u pull grab fan and bolts if ya find a new fan clutch there grab it.Other wise buy new one this way your back to factory setup see if it cures it.That v8 aint gonna mind turning a fan.People are gonna say replace this replace that you end up spending a lot of money that way. jm2cw...

Just a suggestion. Some guys with rock crawlers have installed electric fans or bypass switches to add cooling when going very slowly. When you're pulling lots of torque and barely moving, heat becomes a problem.
My first experience with 4X4 offroading was with a 3/4 ton Chevy. The viscous drive fan wasn't cutting it, so I bolted on an ordinary engine driven one. End of problem, and my big 350 didn't even notice it.

No, you just install a switch to bypass the normal automatic control ON DEMAND, only when you want it. It just requires another power source.

When we do trail runs, and take a break, everybody cuts their engines. I leave mine idling.

That bypass switch with a factory set up sounds pretty good to keep the engine below 210, am afraid if i do it with the current fan the temp will still climb as i use the jeep even if its running at all times; i'll try to find a used factory set up this weekend hopelly that'll do it i'll let u guys know
