Question about Heating & Cooling

Open Question

Jeep Grand Cherokee 2001 3.1 turbo diesel. Low coolant level light comes on on dashboard after 10 seconds. I have replaced the sensor and checked coolant level but light still comes on. Vehicle has only done 56000miles but I had light come on about 12 months ago and problem was cylinder head gasket. Had that done and all was well until light came on again about month ago. I've had cylinder head tested and ok. Any clues as to the solution would be appreciated

SOURCE: My goodman heat pump has

After system has been running 10-15 minutes, the discharge air temp should be 18-22 degrees colder than the air being sucked in. If the air is more than 22 degrees colder then the problem is with air flow. Check filters, blower speed, make sure all vents are open, is indoor coil clean. If the discharge temperature is less than 18 colder, then the problem is with the refrigerant portion of the system (low charge, improper flow control of freon into coil) the key is if you have an orfice or a TXV (Thermal Expansion Valve) to control the flow of refrigerant into the coil. TXV's are known to fail with intermittant problems, however, most 10 seer systems do not use a TXV, they use and orfice which could have debris in it affecting the flow of freon. Hope this helps. When you rate my solution, please keep in mind that I am a technician that normally diagnoses equipment by checking it out in person. I do the best that I can with the information that you provide me on Fix-Ya.

Thank You,

No, heat exchanger is most likely cracked. Time for a new furnace. I cannot see your reply due to some tech issue w/ the site, so it may be a day or so before I can reply again. Please leave feedback for me if appropriate. Thanks

Coolant sensor wiring would be the next place to look. Make sure connector is good, and look for broken wires.

The coolant sensor light is on


The coolant sensor liight come on when the Anti-freeze get low. Just top off the ant-freeze and the light will go out. It is norrmal for anti-freeze level to go down but slow. Toping off once or twice a year is ok but anymore then that you really should check for leaks. Low anti-freeze will cause over heating. Over heating can wreak an engine.

My dad put a new thermostat in my 2001 Jeep Grand Cherokee and it is now telling me my coolant is low and it is not. I just need to know how to reset this.


your low level sensor may be stuck sometimes a light tap on the sensor will repair the issue,make sure your coolant level is ok in the radiator and the overflow tank

1999 Jeep Grand Cherokee Lerado, low coolant alarm


This same thing happened to mine. It only happened in really cold weather though. I added a few inches more of coolant into the overflow. It fixed the problem. I also discovered if that is not the problem, the sensor in the overflow can go out and a replacement is about 20 bucks.
