You did not list what year or engine BUT: Overheating can be the product of either poor coolant flow through the radiator (either restricted air flow from leaves bugs etc. or internally blocked coolant passages.) Or, and air-lock in the system from not properly re-filling after service (generally overcome by filling as the engine warms up with the heater turned on high heat).
If the engine overheated substantially before the repair was made, you may now have a blown cylinder head gasket, or, a cracked cylinder head. Evidence of this usually is exhaust in the cooling system (testable with proper equipment), Water or steam coming out of the tail pipe when running that continues after warm-up, or, coolant in the engine oil. (when in doubt drain, and watch for coolant, which will come out first as oil will float on it.)
Water pumps generally still work even when the seals or bearings are gone, providing the system is full. Cap will usually cause a delayed overheat as coolant escapes under pressure over a period of days. (all other leaks can do that as well)
Replacing the thermostat is always a good thing to do providing you put it in correctly (properly positioned in bore and spring end towards the inside of the engine)
Additionally, your cooling fans must be working. Electric fan should come on, especially when the engine is overheating. Mechanical fan should lock up and not freewheel again, especially when in overheat.
Aside from system testing, you always need to maintain a 50/50 mix of water/antifreeze. That raises the boil temperature of the system above the 212(f) of plain water....Too much coolant will lower it though.
Any questions about anything you find and don't understand? ASK.

03 Chrysler Voyager heat not warming up. Heater core good, new water pump, not leaking coolant, A/C works fine. Any suggestions?


Perhaps the thermostat is stuck open. That would cause the water to circulate constantly and not trapping it in the block long enough to heat up. While your vehicle is cold, remove the radiator cap. Have someone start the car. You should not see water circulation thru the radiator. That should only happen when the hot water in your block is exchanged with the cooler water in the radiator.

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.

My mechanic told me I had a radiator leak. I replaced the radiator. The car still overheats. I have talked to my mechanic several times and now he says I need a thermostat. Whay didn't he replace the...


the cooling systems consists of a radiator, radiator cap, water pump, thermostat, hoses, heater core and sometime a heater control valve that open water lines to heater core. You may need a cooling system flush if water pump, radiator have been replaced. flush the system.change the thermostat and have the heater core checked too if you can get to it.
does the cooling fan kick on to cool the radiator..check that too.replace radiator cap and check cooling fan yourself...let me know if need anything else.
Thanks for using fixya and please vote.

The heat in my 93 talon dont work. the fan blows, and i have flushed the heater core. still no heat. it is getting cold in kentucky. please help.


If you have flushed the heater, I assume you did this by removing the hoses from the thermostat housing. If there's still no heat, check

1. the thermostat is actually present. If not, put one in. If the radiator core is in bad shape, or blocked, replace the radiator.

2. the thermostat is not jammed open. If so, replace it and use a new gasket under the cap.

3. Verify that the water pump belt is not loose.

4. Remove some dash panels to get access to the heater core valve. Check that the valve is actually turning when you adjust the dash control.

Toyota wont start over heated replace the thermostat and radiator cap could it be the water pump is bad how do I tell


if it wont start immediatly after it overheated then you may have blown the head gasket, or melted a coolant temp sensor or other sensor or wire. look closly for the melted stuff. remove radiator cap and fill with water to the top of the rim. have someone crank it and if a air bubbles come out while cranking then a headgasket is most likely blown. some little bubbles at first dont mean nothing. its a steam of bubbles the whole time its being cranked that indicates head gasket

Over heating, thermostat replaced, radiator, engine, and heat core flushed, no water in exhaust.fans working, water pump flushes water thru.


You may have air in the system. Let the engine run with the radiator cap off until the thermostat opens. Have someone then get in the truck and bring the rpm up to 1800 to 2000 rpm and hold it there for 15 to 20 seconds while you top off the system with coolant and put the radiator cap tightly back on. Then bring the rpm down to idle and road test the truck. DO NOT BRING THE RPM BACK DOWN TO IDLE UNTIL THE RADIATOR CAP HAS BEEN INSTALLED COMPLETELY. I suggest replacing the radiator cap at this time also.

The bottom hose will not contain an air pocket. Check your water pump. When the engine is cold, take off the radiator cap and start the engine. When the engine temperature indicator shows normal operating temperature, you should be able to see the coolant moving through the radiator. If not, the water pump is not working. Could be a missing belt, could be a bad pump.

try bleeding the air out of the cooling system right after you start the motor up. this will allow you to get all the air out but not steam. do this until the coolent comes out. common cause, it could be vapor locking and not letting the coolent flow causing OVERHEATING. hope this helps
