Sounds like a CPU problem. your radiator may need a good flushing a s well. i would also check the heater core for any unusual problems like seal break or leakage.

SOURCE: radiator fan not working replaced relay,temp

You didn’t mention replacing the temperature sensor located on the block in the path of the ‘cooled’ coolant.
I can’t tell you any closer where to look for it since you didn’t specify which engine you have.
This device is a solid state item called a thermistor.
With the air temperature around 77 degrees F and a 'cold' engine, it should measure about 10,000 Ohms and hot, around 1,200 Ohms while disconnected from its mating connector.
With the ignition on, and the connector disconnected from the sensor, you should measure about 5 volts coming from the ECU.
If this has failed, the ECU is not getting the right info back from the sensor and doesn’t know if the fan is needed or not.

SOURCE: 98 JEEP CHEROKEE, TEMPERATURE GAUGE

did u bleed the air from the cooling system? if not u need to do that, u have air pockets getting around the thermostat, to bleed raise the front up as high as poss with a floor jack, fill the radiator and coolant recovery tank as full as poss, then run engine until it reaches normal temp, then shut it down and run cold water over the radiator,this will draw the coolant out and the system will bleed the air out.

How do you change the oil pump on a 1996 jeep grand cherokee limited 5.2 liter.The oil pressure drops almost down to zero when in idle normal operating temp range range. Need steps.


I'd be checking to make sure that the oil pump was not the problem before I tried to replace it.
How many KM/miles on the engine?
Regular maintenance?
Burning oil?

NEED TO KNOW AMOUNT OF HOURS TO REPLACE HEATERCORE IN A 2OO1 JEEP GRAND CHEROKEE


call your shop and ask. (ask is a flat rate shop or real)
all that varies, by many factors
the shop, the number of person doing 1 job.
the skills that day
the problems found, on the way to the CORE.
etc.
why ask this, here, ask the real shop. or ask 3 and average.
i looked at alldata.com for you , 63 steps out and 63 back in.
nothing trivial.
my guess 8hrs labor, min.
im sure, most shops would say im full of beans. for 100 reasons.
my 8hr is me doing it the 2nd time.
best case, and a helper.
and having all parts in hand and spark security screws.
and no breaks, no coffee brakes, or beer.

2000 jeep grand cherokee laredo. It is surging between 1500 and 2000 RPM since I picked it up from auto shop...had the rear main seal replaced along with idler arm and bearing and oil pan gasket. Why is it...


Take it back to the last people that worked on it!!!!! If it wasn't like that when you took it there, it shouldn't do it when you get it back.
You paid them money,,,,make them earn ALL OF IT.

I have a 2004 Jeep Grand Cherokee Laredo, it runs toooo hot, i have to keep my heat running even when we have warm weather!!! During the winter i have no issues with over heating. What is causing this?????


Your temp should run about 210 degrees (f) If you need to keep the heat on to keep the temp down likely the radiator is partially obstructed either externally (leaves or other debris) or internally (rust or calcium deposits).Most over the counter flushes don't do much but it's worth a try. Generally the best option is to have it professionally flushed or replace it with a known good one from a scrapyard.

2000 Jeep Grand Cherokee with a 4.0L engine... the temperature only rises to about 150 degrees and stops... sometimes lowers a bit even at highway speeds. Normal operating temp is about 210-215 degrees. ...


The thermostat controls the temp of the engine. The temp sensor tells the gauge what temp to display. If the heater is still putting out a lot of heat then it may be a false reading temp gauge. If however the temp is noticibly cooler then replace the thermostat. A stuck open thermostat would also cause the engine to warm up slowly. check for a loose/dirty connection at the plug on the temp sensor.

1999 Jeep GC is leaking at the plug. Is this a common problem?


If you have a radiator repair shop near by, have them fix it for you.you take it out and they fix it.Or replace it.Now if you are really good and want to save money you can try to epoxy it with a high temp resin repair kit.cleaning is the most important part to make this work.
