I have a 99 oldsmobile alero v6.... i changed the thermostat,water pump,water jug,head gaskets i have no cracked heads are leaks. why is my car still running hot???


If your radiator is of copper, the cooling fins could be deteriorated to a point that it falls apart just by touching them with your fingers. The back side may look OK but it deteriorates from the front by rain, wind and debris.

My 99 Alero just shut off while driving could it be the fuel pump.


Water on the floor that doesn't come in on your feet is usually from one of two sources: a windshield rainwater leak, or a blocked or disconnected A/C condensate drain line. If the water seems to increase when it rains, a leak is more likely. If it worsens mainly when you use the air conditioning, then it is probably a condensate drain line issue. Windshield leaks can be hard to locate and fix, but blocked or disconnted drain lines are much less a problem to have fixed.

My 99 alero v6 is over heating not leaking ight mite be hoses or thermostat . or head gasket but when it overb heats the smoke comes from the top of the engine


REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP.IF CAR OVER HEATING WHILE IN MOTION.MORE LIKELY ITS THE THERMOSTAT,LOW COOLANT IN RADIATOR OR COOLANT SYSTEM,BAD WATER PUMP,WATER PUMP WEEP HOLE IS LEAKING, WATER PUMP NEEDS REPLACING.CHECK ENGINE OIL,IF OIL LOOKS LIKE MILK SHAKE YOU HAVE LEAKING HEAD GASKET.IF CAR IN PARK AND OVER HEATS WHILE IN A LONG TRAFFIC LINE OR.BANK DRIVE THROUGH COOLANT FAN NOT TURNING ON, BECAUSE THE ENGINE COOLANT TEMPERATURE SENSOR FAULTY.CODE SCAN CAR FOR FAULTY COOLANT FAN RELAY OR FAULTY PCM. CHECK COOLANT FAN FUSE, AND HOT WIRE THE COOLANT FAN TO MAKE SURE ITS WORKING.IF COOLANT FAN DONT WORK WHEN HOT WIRED. COOLANT FAN NEEDS REPLACING. REPLACE BOTH RADIATOR HOSES, REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP.BUY NEW COOLANT ADD 50/50 WATER AND COOLANT.IF ENGINE OIL HAS ANTIFREEZE IN IT.REPLACE ENGINE OIL AND OIL FILTER TO KEEP FROM LOCKING UP THE ENGINE.GET CAR FIX.DONT KEEP DRIVING IF IT KEEP OVER HEATING,ENGINE DAMAGE WILL OCCUR.I HOPE INFORMATION I GAVE YOU WILL FIX PROBLEM.PROBLEM COULD BE LEAKING RADIATOR HOSES BUT CHANGE THERMOSTAT THATS FIRST THING I WOULD CHANGE BECAUSE IF IT CLOSED, ENGINE WILL OVER HEAT AND CRACK CYLINDER HEAD OR CRACK PISTON, COOLANT NEED TO CIRCULATE THROUGH THE ENGINE TO TAKE AWAY THE HEAT FROM ENGINE.

2001 Olds Alero suddenly quits sending heat then sometimes it does and sometimes it overheats. Is this a water pump or a thermostat. Help. Mallory M


Check the cooolant level, sound like theres a leak somewhere, water pump, hoses, t-stat bad, rad cracked, heater core leaking, bad rad cap, cooling fans not working, you need to get it looked at really soon, before you get it to hot and blow a head gasket.

1999 Olds Alero. Low coolant light comes on and stays on even though its full. Starts running hot to the 3/4 mark. When the heater is turned on it cools off. Could this be the thermostat or the water pump.


TAKE RADIATOR CAP OFF WITH ENGINE COLD AND CHECK WATER ..MAKE SURE RADIATOR NOT BLOCKED,,PLASTIC BAG ETC. THIS SOUNDS LIKE LOW WATER OR RADIATOR ..STOPPED UP INSIDE ..IF YOU HAVE GOOD HEAT IT'S FULL OF WATER. REPLACE T STAT B4 RADIATOR..IT'S CHEAPER. ALSO CHECK FOR RADIATOR COOLING FAN OPPERATION..I,M RULING OUT THE WATER PUMP.

I HAVE A COOLANT LEAK AND HAVE REPLACED THE WATER PUMP BUT THAT HAS NOT SOLVED THE PROBLEM. IS THER ANY HISTORY OF THIS IN THE AURORA.


I purchased a 99 alero that was running hot. I thought it was a coolant leak, but the mechanic told us it was the radiator cap and that the psi wasn't holding the pressure.In which of course the water would leak out due to pressure. He gave us an 18 psi cap, which did in turn help the overheating. Hopefully this is helpful.

YOU MAY HAVE A LEAK AROUND THE FRONT WINDSHIELD. CHECK THE RUBBER MOLDING AROUND THE GLASS. YOU CAN SEAL IT UP WITH SOME SILICONE AT THE EDGES. IF YOU HAD A WINDSHIELD REPLACED TAKE IT BACK AND THEY WILL PROBABLY TAKE CARE OF THIS FOR YOU.

HEAT


i have just done this on mine after fixing a leak. yours is a simple one, you have an airlock. run the car till warm, remove the water filler, leave about 2" from the top and leave it running. eventually the air will come out. make sure you have the heating set onto hot front and back
