This is an indication that there is a problem in the cooling system. Check the radiator cap is operating correctly. Check for correct operation of cooling fans ( replace if you have a viscous fan hub on the fan). Have a flow test done on the radiator as there may be too many cores blocked for efficient cooling. Run the fault codes to check for air/fuel /timing issues that will affect the engine operating temperature.

2002 cavalier ac runs cold for a period then runs hot air out that go back and forth never staying cold


That is because the pressure in the AC system is either getting too high or too low and the pressure switch cuts it off till the pressure drops to a normal. During that time, the air gets hot and then the switch comes back closed, the compressor comes on and the process starts over. You need a manifold pressure gage set to diagnose.

Why does 2000 s40 volvo turbo runs hot and the fan stays on after shut off


fans are designed to run on after you shut engine down as engine temperature rise after switching off . running hot could be caused by the top hose having gone soft when you rev the engine the water pump sucks the hose flat stopping the coolant flow or the radiator is blocked and need flushing out

can your fast right foot , save the stall, and easily?

ok stalls 101.

2: lost engine compression.
3: lost spark.
4: lost fueling or floods
there is a simple test for each.
do you want more guesses, or how to do tests.

OVERHEATING ( SOMETIMES)1996 460 RUNS HOT ON TRIP 200 + MILES LOST NO FLUID --NEXT DAY EVERYTHING OK--DROVE 3000MILES OVER 3 WEEKS NOTHING HAPPENED. PARKED FOR APROX 1 AND HALF MONTHS-RUNS HOT--CHANGED...


Possible fan clutch..Usually if its a fan clutch it will run hot sitting still but cool off once going down the road..If it takes a while to run hott then i would suspect a clogged radiator..When you drain it did it look like all the antifreeze came out..Ive seen half the radiater clogged up where half of it drained but the clogged section stay in the radiator

When I turn my car off the air conditioner still runs-I needed a jump the other day because it ran all night and wore the battery down.


OK, if the relay for the A/C fan is bad, then the radiator's fan will keep running after turning off the ignition. Also, if the fan for ventilation of the A/C in the cabin stays on after the ignition is turned off, the relay for that is bad.

Good luck on this repair.
