Possible loose AC belt but more likely a water pump issue. Putting the AC on puts more strain on the water pump to circulate coolant which also would impact the AC performance.

1995 Aerostar engine runs hot when stopped . when ac is running it goes the temp. goes up when off the temp goes down normal


I would start by checking to see if the fan is running. With the AC on, the fan should come on automatically. Could be a bad relay, bad fan motor, blown fuse, etc.
Should also check the belts and cooling system.

My 1999 Chevy Malibu runs hot? It started when it overheated. We changed the thermostat, then water pump, then temp sensor gauge and the temp gauge goes high but only when the heater stops blowing hot...


Air pockets will make the guage do that, and also cause your heat to come and go. Also, a poor radiator, as in rotting, or plugged up, will cause high temperature issues.

Hi have a 2004 freestar I changed radiator-, water pump , thermostat, engine coolant if I drive on flat street my van runs good temp is normal but if I go uphill the gauge goes up to almost red once I...


Sounds like a faulty temp guage/r a strange malfuntion in a sensor to me as well, only doing it when it going up hill really makes no sense for the way the cooling system works so I doubt that its actually running hot, which is likely why he asked about the gurgling noise, it would force water back into the resivoir if it was running hot assuming that the thermostatic radiator cap is working properly.

Temp gauge goes to hot and engine looses power.


hi.. your coolant temp sensor may be getting a bad reading, it also opperates as a compensator so it may effect the power of the vehicle.. check that the engine is actualy hot when it says and your car will probably run alot better if you change it anyway..

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.

Engine and hood extremly hot new thermostat installed and temp gauge working properly why so hot?


Make sure you're using proper amount of coolant in the water. You could have dirty fins or something blocking the front of the rad preventing it from cooling enough or might be rad clogging up. If gauge goes over half way then I'd worry. I'd remove rad and use rad cleaner or get it cleaned professionally.

97 Hyundai Lantra. Temp gauge shows engine very hot


If the replacement thermostat is good, and installed properly, then the temp sensor might be bad. I hate to tell you ($$$$$) but waterpump could be bad (more expensive)

The heater is only blowing cold air


First, check to make sure you are not low on coolant. Check hoses going to heater and see if they are getting hot.(one should be hot, the other should be slightly less hot but not cold or just warm) Check heater control valve to make sure that it is operating, Check that plenum door is opening properly inside the cabin, in the heater box. If you have done any work at all on cooling system, run the engine 'till it reaches operating temp with radiator cap off...sometimes htr core can become air-bound. Also...goes without saying, but make sure that engine reaches normal operating temp while driving. If not check thermostat!
