Jeep Still Running Hot, after replacing everything. Any Ideas?
Hey guys, I've got a 99 jeep cherokee sport, 4.0L V6. I've been using this vehicle to tow for years, and the only problems I've ever had with this jeep, are cooling related...
Here's the lowdown...
I've replaced, the radiator, two years ago. new hoses around that time. All my fans are good, (Thinking about replacing, they are old). I've replaced the Freeze plugs in the engine block, because they had holes in them.
I just had a new head gasket, new water pump, and new heater core, new thermostat, less than two months ago. new radiator cap.
I've taken my jeep to my buddies shop and used the vacuum radiator flushing system, and flushed it 4 times and it looked like mud water, even after flushing 4 times. Came back a week later and did it again, and have the radiator looking halfway clean again. Thinking about going one more time to be sure. I'm sure it's loosened some more grime up in there.
I used a laser heat gun and took temp readings, and the newer radiator looks a little sketchy, I'm thinking that even though it's relatively new, all the nasty stuff in there, could have clogged it.
I'm thinking about a new radiator, but I don't really think I need one. But if I got one, I'd get an aluminum radiator. But I shouldn't need to do all this. If all this stuff, doesn't work, I'm thinking about other things I could do to improve the cooling on my jeep, Any Suggestions?

Have you checked the timing? Too slow will make it run hot. Thermistat in backwards or non existant? Does it have electric fans? Good shrouds? The stock radiator is about $200 or so and the aluminum is well over twice that and shouldn't be necessary. You may have some blockage in the block itself as well. Do a good engine flush?

Check the tranny temps. Sometimes the tranny shares the same radiator as the car and can cause higher engine coolant temps if tranny is running hot from towing and or if it's on it's way out.

Yea if your Jeep didn't come with a tranny cooler I'd jump on one anyway. Cheap and easy to install and could seriously impeed the premature death of your tranny, especially since you are hauling with it.
