Electric Fan Question
That is a major issue right there,HOAT coolant only not OAT coolant that prestone makes. Besides that the fan operation is 100% normal but might want to check how many amps the fan is pulling since the wires should not be so hot you can not touch them,they will get hot(come on it's inside the...- tjkj2002

Pulsating Brakes
Oh yes they do,seen some so bad you can see the wobble on a brake lathe. Best to replace rotors when you replace the pads,turning rotors just makes them heat up faster since your removing material that it needs to dissipate heat.There cheap enough,in most cases cheaper than a good set of pads.- tjkj2002

LED interior lighting issue
The BCM controls the interior and exterior lights by grounding the circuits,it's all resistance based and LED's do not have enough resistance for the BCM to fully turn off while running. I would not add any resistors for the interior,they get hot and are a major fire hazard when placed in the...- tjkj2002

Inspection results
The timing cover is a much easier job than the oil pan gasket,maybe 1.5-2 hour job. Trans output seal requires the t-case to be pulled,might as well replace the t-case input seal while it's out. The oil pan will require the cradle to be dropped or engine raised and both those methods are...- tjkj2002

"Dead" cylinder with compression??
If your engine is struggling and have a P0420 your going to need new cats,there plugged restricting flow and choking the engine. Easy way to tell is to remove both up-stream O2 sensors and take for a short drive,if the power is back the cats plugged. Oh and your flywheel better not be...- tjkj2002

2004 Liberty 3.7 v6 overheating, bad catalytic cv
Looks like someone unloaded it on you with severe engine issues due to neglect. Just plan on a engine replacement and most likely a full cooling system replacement. 3+qts low on oil and no coolant is a sign of a bad repair job on a severely neglected engine and the owner didn't want to put...- tjkj2002

What brand Ignition Coils for a 2003 Jeep Liberty 3.7
Don't use any,messes with the spark plugs ground. Don't need and dielectric grease either,okay to put on the sealing o-rings on the coils but that is it. Can't tell you how many vehicles with misfires where due to over-use of both those products and throw in people using the wrong plugs.- tjkj2002

The electric cooling fan comes on at 219 degrees(+/- a few degrees) when the A/C is not selected(or defrost).The AUX clutch fan for HD cooling "locks" at 230 degrees for the OE clutch. Should shut off at around 199 degrees or so. The Temp guage is a "dummy guage".At the half point your...- tjkj2002
