Ask yourself, how did the debris get all the way to the radiator? Through the condenser? Or around it somehow? And A19 has a valid point. I have seen condensers clogged with gnats, while the surface is clean. I always recommend deep cleaning the fins with a strong surfactant like simple green, spray...

That is an ongoing problem with electric fans. No real metrics for the OEM motors, and aftermarket stuff is all over the place. Usually the difference between ram air & parked cooling is a good indicator. Duct taping the gauge set on the windshield on the passenger side & going for a drive w...

Sorry Danny. After a19 starts clogging up a thread with useless junk I just scroll to the end - where I see pressures as high as 400 psi. I missed the part where you sprayed the condenser. You say the fan blows well. But what is well? is it 75% of what it did when brand new? The only metric we have ...

18 year old electric fans. You are chasing your tail. Spray the condenser with water and watch the pressures. You should be able to get the system to stabilize at the control valve pressure on the low side - if you can get rid of the heat. We went through this at length on the old board. The electri...

Most people here do their own work, although sometimes we can tell you who to avoid...

Good luck in your search. As others have said, avoid tire shops - and any place adjacent to a junk yard.

If that FS18 drags the 4.6 down when cycling you are pushing your luck. Grab the clutch plate on the compressor & turn it by hand. If it is gritty or notchy you have some parts to replace. Running it with 60f vents at idle means it is really low on charge. Driving it like that keeps it from retu...

Brielly: Go to https://www.eautorepair.net/Marketing/Default.asp And spend the 20 bucks for a one month subscription. You will get access to the FSM data and full wiring diagrams. The sensor calibration points. The fan logic path. And any temperature / pressure reference data that Jeep provided for ...

Your mechanical fan clutch is shot. The mechanical fan is the most powerful air mover under the hood. The electric fan is an add-on to help in extreme conditions and with the A/C. Again, Jeep has changed the aux electric fan operating parameters several times over the years. Some are supposed to com...

Does this vehicle have a mechanical fan and an electric fan, or only an electric fan?

Jeep has changed the fan configuration too many times to count.

What is the ambient temperature for those pressures?

Was this at idle or 1800 rpm?

Which engine in this truck?
