Sounds like head gasket, shes putting pressure out into your rad, check your big hose when idling see if they swell up with pressure,another way to check is to leave rad cap loose.

SOURCE: 2001 Monte Carlo continuously overheating...

DID YOU BLEED THE COOLING SYSTEM.THIS VECHICLE WHEN YOU REMOVE MOST OF THE COOLANT TO REPLACE WATER PUMP OR RADIATOR AND THERMOSTAT YOU HAVE TO BLEED OUT THE AIR TO GET COOLANT TO CIRCULATE PROPERLY. TO BLEED COOLANT SYSTEM WITH ENGINE COOL LOCATE BLEEDER SCREW AT WATER PUMP BY HOSE OPEN BLEEDER SCREW A LITTLE TO LET SOME AIR OUT WHILE YOU.POUR ANTIFREEZE IN RADIATOR.WHEN RADIATOR COOLANT LEVEL STOP DROPPING CLOSE BLEEDER SCREW AT WATER PUMP BYPASS HOSE.START ENGINE LET IDLE UNTIL GET WARM AND COOLANT DROPS IN RADIATOR ADD MORE COOLANT.WHEN COOLANT START RISING AT RADIATOR.PUT CAP ON RADIATOR LET VECHICLE IDLE A LITTLE AT A TIME.UNTIL THERMOSTAT OPENS THEN YOU CAN WAIT A LITTLE WHILE TAKE A LARGE RAG OVER RADIATOR CAP OPEN A LITTLE YOU WILL HEAR AIR STEAM HISS THROUGH CAP BUT DONT OPEN ALL THE WAY.WHEN HISSING STOP SLOWLY OPEN RADIATOR CAP A LITTLE AT A TIME SO YOU WONT GET SCALDED.YOU CRANK ENGINE UP A LITTLE STOP WAIT A WHILE BEFORE OPEN RADIATOR CAP.KEEP DOING THIS PROCEDURE UNTIL RADIATOR COOLANT STOP DROPPING.WHEN COOLANT STOP DROPPING.BLEEDING COOLANT SYSTEM COMPLETE.IF VECHICLE KEEP OVER HEATING CHECK OIL CRANK CASE LOOK LIKE MILK SHAKE YOU HAVE A BLOWN HEAD GASKET.

SOURCE: just had water pump installed in 2001 impala,

water pump may not be sealed, have a look under the car for a few drips if it was the theromstat the pipes would expand not collapse. or maybe any water hose thats not sealed properly

SOURCE: overheating

It could be your head gasket.

SOURCE: 1993 chevy camero- thick, rusty colored residue in radiator

The rust is probably in the engine. There are many little pockets, water ways, water jackets (around the cylinders), etc, so getting all the rust out without dunking the block and heads in a cleaning tank is about imposible. I would recommend giving it really good flush every 4 to 6 months. I would try flushing the radiator before replacing it because it is probably not rusted, even though it is full of gunk.

The is likely air trapped in your cooling system and as it moves the problem comes and goes. Check your coolant level and apply vacuum to the surge take to evacuate the air pockets.

My 2001 a6 2.7l twin turbo is overheating even try to run heater but now blows cold air only. What could it be, thermostat, or clogged radiator, or water pump? Please let me know what you think!!!

The thermostat would not stop the heaters from getting hot . Is flush out the heater matrix make sure water flows nice and free . But I would be looking at the water pump and at the same time flush main radiator and heater matrix at the same time. The thermostat stuck shut will cause it to overheat but not stop the heat out of the blowers.

My Wife's care overheats and the heater only blows out cold air.

check that the thermostat is in correctly as it will cause no circulation but overheating. have a compression test done to eliminate head gasket /cracked head. There could be a blockage in the heater core but I am thinking that by passing the heater fan he has also by passed the actuator( coolant valve) for the heater core. Water pumps suffer from bad bearings and very seldom anything else. check that he hasn't blocked off the water to the heater core as well
the throwing back of the coolant is the boiling of the coolant in the block ( bad head gasket) due to lack of circulation. It may be a blocked radiator as flushing doesn't fix the blocked cores . If that is the case a new radiator is in order.

Last year my 2005 Chevy Impala water pump went out I change the water pump thermostat and that was it change thermostat free other times after that do the bad thermostats the overheating never really...

If you have changed the water pump AND the radiator AND the thermostat and still have the problem then the hoses should be checked to be sure they are not collapsing, also make sure that the coolant is 50/50 water and coolant and the thermostat is installed right.

I have a 2001 Oldsmobile Alero. For the second time in a year my car has been overheating. The first time the problem actually went away after a few days before I even had the pressure tested. This was...

First the reason the heater is not working is because there is air in the system and these engine are known to trap air.There is a bleeder at the top of thermostat housing to remove the air.Take the radiator cap off while the engine is off and cold and add coolant/water mixture till fluid streams from bleeder screw(will need to be removed) then tighten screw and install radiator cap.Let it idle and see if it over heats and pay attention to the cooling fan operation and heater operation.If it does not overheat after 20 minutes the take it for a drive and see if it overheats.I fit does not overheat idling but does overheat driving you have a bad radiator.Dexcool is great for pugging radiators and heater cores.It is possible to flush the radiators and fix sometimes but new ones are not that expensive.I would probaly replace.If it overheats idling and fans are working suspect a bad thermostat.Good Luck!

2000 3.8 Impala keeps overheating even after changing thermostat. Did not overheat after short trips, after changing it, but started back after driving over 20 miles. Temp gauge goes to red and coolant...

Sounds like there could be an air pocket in your cooling system. If the job was done by a mechanic take it back. If a "friend" helped you, tell him to rebleed the system. Also seems like your water pump might be bad. If it was overheating before changing the thermostat and is still doing the problem only worse then I would assume the pump needs to be changed. If the pump is bad, there is no doubt that air is in the system still and causing the overheating to occur even faster.

Radiator cap allows overheated fluid to backpressure reservoir

Sounds like a sticking thermostat (temp up/down).
In an emergency, you can remove it, but replace it soon.

I otherwise suspect the radiator fan, but it shouldn't overheat if you are on a highway going faster than 50mph (enough air blows through the engine compartment).

Everything else you describe does not indicate any other solution.

I suppose it could be the radiator fan RELAY SWITCH or loose wire to it.

Hope this helps....

Replaced waterpump, still overheating lights comes on

Check to see if there is water in the oil...If there is water in the oil then it could have a head gasket problem..Did you ever replace the thermostat? If it is stuck then it would also cause overheating...Excessive exhaust backpressure because of a clogged catalytic converter could also cause overheating..Also check belt tension and condition. A loose belt that slips may prevent the water pump from circulating coolant fast enough and/or the fan from turning fast for proper cooling...Another thing it could be is a faulty Water pump -- Any wobble in the pump shaft or seepage would call for replacement. In some instances, a pump can cause an engine to overheat if the impeller vanes are badly eroded due to corrosion or if the impeller has come loose from the shaft. The wrong pump may also cause an engine to overheat. Some engines with serpentine drive belts require a special water pump that turns in the opposite direction of those used on the same engine with ordinary V-belts... Also check the Fan -- With mechanical fans, most overheating problems are caused by a faulty fan clutch, though a missing fan shroud can reduce the fan's cooling effectiveness by as much as 50% (depending on the fan's distance from the radiator) which may be enough to cause the engine to overheat in hot weather or when working hard.
