Check gauges light on! - temperature lines goes to max -  then back to normal (middle)

    After driving my 01 cherokee (with 62,000 miles on it) aprox. 1/4 mile the temp guage went as high as it could go then went back to okay range and back to the max. 1 mechanic looked at it and originally said it was the thermostat and it needed to be replaced immediately and upon the next call 1 hour later that there was exhaust gas in the cooling system and now thinks it would be better to replace the head gaskets. Has anyone else had this problem?

Yes, this is a common problem for over heated engines with aluminum heads. Once the engine over heats, the aluminum changes shape and warps so the head gaskets no longer seal, thus the exhaust gas in the water. The mechanix was correct. The antifreeze in the oil makes for a very abrasive compound and will wear engine parts excessively very quickly. At one time in my life, I had this problem with a Cadillac Cimarron. In 2000 miles, it actually ground the cam lubes to circles. A big mess.

So get it sealed up as soon as possible.

Regards,

My check gauges light is on, oil hands goes over to zero, moves up, light goes off, when it drops back to zero, gauge light comes back on.


Well the warning light is supposed to come on if any of the gauges display a dangerous condition, such as no oil pressure.
You may have a faulty sending unit for the gauge, or a wiring problem, or the engine may actually be loosing oil pressure when the gauge drops.
You could replace the sending unit as a test, or have someone check the oil pressure with a mechanical gauge.

Check gages on jeep grand cherokee


If your "Check Gauges" light is on, the light means pretty much whay it says...CHECK GAUGES! One or more of your gauges is/are reading outside of normal operating range. You could be having an overheating problem (Temperature gauge near or in the red) You could be having a charging system problem (Battery or Amp gauge reading in the "discharge" or "low voltage" area.) You could be nearly out of fuel (Fuel gauge reading near empty) Your oil pressure could be low (OIl Pressure gauge reading very low)....You have to look at your gauges to find out what is going on that is not normal.

the first thing to try is turning the heater upto full heat(a/c off)if the temp guage goes down THEN CHANGE THE THERMOSTAT...(hot oil,if too hot, is thinner than the normal sae rating so the oil pressure will be lower.otherwise no real problem.

My 2001 Jeep Grand Cherokee Loredo, straight six, is having a problem that the oil pressure gauge goes to 0 and my check gauges light comes on but when i accelerate it goes back up and the light goes off. ...


Your problem could be the result of a bad pressure sending unit but I would take care of that immediately. If the pressure doesn't return to normal after installing the new unit, do not drive 'til you have a mechanical gauge installed and the actual pressure checked and the problem corrected.
