#5083 of 5143 Re: 2004 Jeep Grand Cherokee 4.0L Fan Relay Location [mrspanky]
Jul 01, 2012 (5:03 pm)
Great info mrspanky user.
I have an 04 WJ as well, the AC has been giving me some work lately.
In relation to the Fan Relay, mine is not located under the passenger's side headlight, mine is a 2WD standard package. I did see the 2 relays near the battery, but decided not to touch them, instead I hot wired the fan.
The fan was not spinning (mine has a 3 pin connector as well), so I decided to take out the fan completely and buy a replacement (either fan or motor only). Once out I hot wired the motor only, to my surprised it spinned.
So I disassembled the motor entirely, notice you need to be careful putting it back together. The purpose was to clean it from the inside, I assembled it again and tested it, I was again surprised by an annoying noise from the motor on both speeds (yes the 3 pin connector means 2 speeds).
So I unassembled the motor again (fan motor, is the only motor I am making reference to), and found out one of the inside field poles (lets call them poles) was positioned incorrectly. I put clean it all over again, I used some wd40 to make the moving parts move smooth, and I also notice the poles are a little worn (2 of them, there are 4), so I am guessing the motor is about to fail.
Continuing, I assembled the motor, and tested it, worked fine.
Put it inside the fan shroud, tested it, worked fine.
Assembled the fan, tested it again, worked fine.
Assembled the entire fan in the jeep, plug it in, and worked fine.
So I installed only 3 screws, that last one everyone hates to take out can screw itself, because I am not going to...
why? something tells me is going to happen again, the fain will fail, I think is dying.
So, the fan is working ok right now, the AC is engaging normally, and the temperature is staying below the 210 degrees mark.
cost. $0, just a little scratch on my right hand finger.
However, I did change the oil, air filter, and thermostat.
Thinking the thermostat was the reason. I must tell you, I used the commercial kind before, the temperature was reaching a little over 210 before it cool down. This time I went Mopar only (both thermostat and gasket), and spot on.. 195 degrees,and it kicks in.
I also got spark plugs while at the dealer (I got a straight 6, so that's the next project, the advantage about the Mopar plugs, they are already calibrated to the WJ specs).
Thermostat, gasket, and 6 plugs, about $60
Oil (premium fully synthetic), K&N oil filter, and Fram air filter $55.
Next weekend, flush radiator and change spark plugs.... hopefully only labor.
Thanks for reading, and happy work out in your jeeps fellas !!!

#5085 of 5143 water pump issues 1995 JGC Laredo 4.0
Jul 22, 2012 (4:56 am)
i have a 1995 JGC Laredo 4.0 i noticed i am leaking coolant from the water pump i tracked the leak to the bottom of the water pump where the hose connects but the thing is i had the water pump and thermostat replaced around 3 years ago over the last 2 years i have replaced the bottom hose and radiator is it normal to have to replace a water pump that soon or could it be a bad gasket or should i give the place that replaced a call its not overheating or anything like that yet but i dont want it to get to that point im stumped thanks in advance for your time

It is not unusual for a water pump to fail in three years but usually the tell tale leak is from the bearing weep hole, not the bottom of the housing. Coolant can travel funny ways. I would suspect its the gasket, if its coming from the bottom of the housing. I replaced the water pump on my 2004 JGC last month for $50. The new (not rebuilt) pump has a lifetime warranty(Advanced Auto Parts), you can buy the gasket separately for less than $10, or goo it up with permatex and reinstall. If you had it replaced at a garage and have your receipt, see what the warranty terms are. My guess is they replaced it with a rebuilt pump which has a one or two year warranty. Good luck, but you are smart to repair it before it fails and overheats and ruins your engine.
#5088 of 5143 Cooling System Leak ??
Jul 30, 2012 (10:20 am)
97 Jeep Grand Cherokee 4.ol I6: I gave my kid my old jeep to use at college. He is home for summer and I am using it. I worked on it last summer. Replaced water pump, brakes, etc. and all was OK. I am using it this week and it is consuming about a gallon of antifreeze per day. Nothing looks wet. Not a drop of antifreeze on the floor. Very unusual. I fixed a dozen cooling leaks. Engine runs OK. Nothing conspicuous about the exhaust. If head gasket issue, shouldn't I see or feel something. I have had it since 2000 so I know when it's driving OK. I haven't pressure tested it yet. Radiator or radiator cap? Any input welcome. How should I start troubleshooting?

Hi! My Jeep Grand Cherokee 2003 CRD Diesel Engine No: 1J8G8E8A24Y103891has a hard start for the past 3 weeks. I have realized that when it starts, the diesel mixes with the air. There are bubbles flowing through the pipes. I have cleaned the tank. I have bought new diesel filter. I have replaced most of the seals of the pump in front of the engine. We have been looking through the pipe from the tank to the diesel filter. I cannot see any leakage. . When my car is running, it is smooth and has no problem. The only issue is starting. When we start the engine and it is stationary for a while, the diesel starts flowing backwards. The pipes become empty. PLEASE I need some help. If you have any suggestions what next to try, please write back, Thank you!! Samuel Kayuni, Malawi in Africa.

Take the damn thing to the shop before it burns up.

lijeepowner1 did you ever figure out what was wrong with your jeep? I think mine is having similar issues to yours.
