If the relay had not been installed, the overheating would have started immediately, unless the relay was bypassed during the repairs and the fan was being activated by a wire connected elsewhere. Does the fan ever come on while the engine is running? What about when you turn on the A/C, does the fan come on then?

The electric radiator fan runs after truck is shut off. Will turn off after 30-40 min. Is this normal?


no it is not normal....have a repair shop check the coolant fan sending unit or the coolant fan relay...a bad sending unit maybe sending a false overheating signal to the fan causeing it to stay on or the on off fan relay maybe sticking on..an make sure the jeep is not actually running hot the temp guage maybe reading the wrong temp

I have a 2005 Jeep Rubicon Unlimited. A few weeks ago the front end started "wobbling". Usually when traveling between 45-60. Does it randomly and feels like the tires are coming off. Tires...


if wobble before alignment- you have front end damage-upper or lower ball joint or cv joint- if after align ment_TAKE BACK TO ALIGNMENT SHOP- either way have looked at asap.

It overheats when in traffic ior when it is idling


I have fixed my own 2002 Jeep Cherokee twice for the overheating issue. Overheating can be caused by a number of different problems, but one of the most notorious problems for the Jeep is the 'radiator fan relay switch'. When the temperature thermostat goes over 210, it tells the relay switch to turn on the radiator fan to cool down the engine. If that relay switch isn't working, the fan never turns on and thus your engine overheats. Here's a simple test to check if this is your overheating problem:
1. Start up your Jeep, open the hood, and let it run to the point where the temperature gauge on your dashboard creeps past 210.
2. Once it goes past 210, go over to the engine and see if the radiator fan kicked on. (the radiator fan is right behind the grill, circular with big plastic blades) If yes, then the relay switch is working. If no, then you probably need to replace the relay switch or the radiator fan motor is bad. But more than likely, it's the notorious relay switch.
3. Turn off the Jeep asap to avoid damaging the engine.

You can purchase a 'radiator fan relay switch' from most Jeep dealerships if they have a service dept. It should be around $75.
(I saved over $700 by not taking my Jeep to an auto shop to fix this) To change out the relay switch, you need to take off the passenger side front headlight. There's a black plastic guard behind the headlight and the relay switch is located under/behind that guard. If your Jeep ever experienced this problem before, you may see a cut-out where someone replaced this part before. If there's no cut-out, you can check out this link to see a picture of where to cut.

Once you switch out the part, you should be golden.

If i hit a small bump at 50 mph, front ends shakes so bad,I have to stop truck \r\nalso lots of play in steering


My friend, you have very serious wear in the front end of your vehicle as evidenced by the severe vibration when you hit a bump. The front end steering equipment in your Jeep is very complex requiring special tools and expertise to properly repair. Please get your 1995 Jeep looked at soon by a front end alignment specialty shop in your area. This is a very dangerous condition.

Thank you for your interest in FixYa.com

My jeep is overheating. I have changed the radiator. radiator fan,relay, coolant temperature sensor, thermostat, and fan relay and still the jeep overheats, What else can I do?


have a repair shop do a "block test" this test will test the cooling system for combustion gases. If gases are present, you may have head gasket or cyl head leakage.

2007 Pacifica overheated. Outside Temp only 80. Doesnt appear that front fans are working and coolant level in resevior get higher.


Turn on the AC--it should start the radiator fans immediately. If nothing, check the fuse for the fans. The relay for the fans is a solid state device that is controlled directly by engine computer. The computer reads the coolant temperature sensor which tells the computer when to turn on the fans for usual cooling. Try to turn each fan manually (engine cool) and check for bad bearings, or fan blades--both fans should spin freely without any noise. If the fans come on with AC, then replace the temperature sensor which should be located near the attachment area of the upper radiator hose on the engine. It will have a single wire attached, and look like a small brass plug with threads. Watch the engine temperature for a while after the repair as the overheating may have damaged the thermostat element. Hope this helps!

Front end shakes so much it looks like the wheels are falling off


What you have is called death wobble. Generally it is caused by one or several loose components in the steering. You need to have all mounts including where steering box is attached to the chassis checked. Often the problem is caused by either bad ball joints or track bar ends or mounts. Wheel stud torque is also important. if any brake, tire, or other front end work has recently been done, this may be the cause. One item often suggested by shops is the steering stabilizer. It is often damaged by the shaking but if replaced will not cure the problem and will be damaged again.
If everything in the front end is carefully checked and verified as good, then as a last resort, have some additional positive caster added to the front end alignment. That often helps.

I need to find the location for radiator fan relay


inside the front bumper between the front grill and the a/c condenser
The relay mounting location is designed to dissipate heat. Ensure the relay is securely attached to prevent relay "thermal" shutdown and relay damage, resulting in possible engine overheating.
