Question about 2002 Nissan Xterra

2 Answers

I was sitting in stop and go traffic and notice my xterra started running hot. When we started moving, the temp dropped back down to normal. I check the coolant and it was low and I added more. It will stay normal while moving but as soon as it sit a few minutes not moving, it will start to run hot until we mive again. What is the problem?

Sounds to me you may have a small hole in head gasket. You need to take and have pressure tested to make sure, Best of luck to you.

Change the sensor, but it will run hot like that if you are not moving fluids across it. It is basically measuring air temp for a minute. Could be a totally stuck thermostat. Change both. That cooling system is critical on a cherokee.

I have a 2004 Nissan Xterra. It is not cooling like it should. I changed the two filters behing the glove box. I checked the pressure and it is good. The compressor is coming on and sounds like the clutch...


When you say you checked the pressure did you connect gauges to the high and low sides to get both pressures, this sounds like it may be low. also what is the temp coming out of the vents. note on really hot days and humid the ac system doesnt cool as good unless the truck is moving down the road or highway and does take a while to cool down. at a stop or sitting or in traffic the ac temp will rise as the condensor needs to be cooled like the engine does, if its not cooling then the temp will not be cold, check the front of condensor for blockage, also make sure the fan is running with ac on. this fan should run when ac compressor is on,maybe clean condensor with water hose blowing from radiator outwardto front bumper, then make sure the hot/cold blend door is closing all the way,a quick test is to turn a/c on, turn temp control to hot and see if it gets hotter then back to cold and it should get colder. this sounds like the system may just be a little low. have an a/c tech check it, you may find its low or nothing is wrong. good day.

Temp gauge is rising at 3/4 of the way even while traveling down the interstate, once a/c was turned off it started to go back down but would still go up if sitting still running, what would cause this?


change the antifreeze and flush your system, its been hot lately so the motor heat goes up too, having the AC on makes the motor work harder, so thats normal that the temp would rise when its on. traveling on the road allows air to help cool the motor, sitting in traffic slows the air, so there again heat will increase

IT IS NORMAL FOR A VEHICLE TO HEAT UP WHEN THE A/C IS ON ESPECIALLY IN HOT CONDITIONS IF THE VEHICLE IS NOT OVERHEATING THEN THIS IS NORMAL IF YOU WANT YOU CAN ADD A HEAVY DUTY OR HIGHER GRADIENT THERMOSTAT TO BETTER REGULATE THE GUAGE

My car overheats only when i am stopped or going very slow. Otherwise temp is normal. I don't know where to start


Check your fuses first, for the radiator fans. Make sure your fans are kicking on. If they are not, the fuse may be blown. When you are driving, the radiator and engine gets air. That is why it only does it when you are going slow or you stop. Make sure the engine has the correct amount of coolant in it. Check these first. If they all check out, it may be more serious problems, like a thermostat or a water pump. Check for leaking coolant also. If you have any questions, please let me know. I am here to help. Thanks for using Fixya.

Your overflow cap could be your problem. The cap may no longer hold pressure like it should causing small leaks that you don't notice which will make the car run hot. Also it could be the fans not kicking on because of a bad temperature sending sensor. If these go bad, the temp switch don't know how hot the coolant is therefore it will not signal for the fans to turn on to start cooling.

Check out clarks-garage.com he has a complete troubleshooting guide for your cooling system along with a schematic. In short, check the low speed resistor on the firewall. Should be around one ohm.

Overheating


It may actually be a coolant temp sensor problem - they do have issues sometimes. I'd replace that before anything else - they're generally inexpensive (in the $20 or less range). If, when you ask for a new one, they ask you which one you want, you need the one for the dash gauge. Some cars have one for the gauge and one for the car's ECU. Your problem is with the one that drives the gauge, so get that one.
