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

Factory clutch fan cant be beat electric might not be pulling enough cfm for hard pulls.

so do you recommend to back to a factory fan? or should I just get a bigger electrical fan?

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.

By pass switch for your e-fan does wonders. Since i did it, never had an issue again.

Does that mean the fan is running at all times? Anyway I'll look into it and give it a try see what happens thx for the suggestion

dave1123

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.

Yup. When the switch is "off" it works as factory standard. When "on", the fan is constant.

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

sounds like a waste of gas IMO

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

Idling for 3-5 minutes really isn't wasting too much gas.... But the point is, my engine does not get hotter than it should, not it how much gas I waste. =P

Did the bypass switch thing , no diffetence , will do the stick set up ths week see what happens
