1985 vanagon still overheats after I replaced radiator,water pump, and removed thermostat. No circulation below 2800 rpm.

    No overheating occurs if the 2800 rpm is maintained.

  • lckirk Jul 24, 2008

    The water pump will send hot water to the radiator when engine is running at 2800 rpm or higher. The radiator fan is now on manual to ensure cooling when it's needed.

Hello,
The radiator will take a while to warm-up, even with a good
thermostat, so don't be alarmed if it does not get warm
right away after thermostat replacement. Thank you!!!

Regards!!!...

    Hello,
    If the cooling fan isn't automatically kicking to high speed on warm
    days and while the van is sitting in traffic, then this might be the
    problem...

    IF its ok then check for is whether the coolant is bubbling in the reservoir after the
    engine is fully warm. This would indicate a head gasket leak (air
    getting sucked into engine around the failed head gasket)..

    Also check for the fuse #7 which controls the radiator fan..Thank you!!..

Check that the radiator fan is starting and that the water pump is running.

have cooling system pressure tested for external and internal-combustion gas leak that is interfering with the normal engine water circulation. You may have a warped cylinder head. remove and replace thermostat only when it is defective but replace with a new one.

Coolant isn't circulating in the engine of a Jeep 2002 Grand Cherokee V8. Radiator was just replaced as well as the water pump and thermostat.


Hi Jonny, While the engine is cold the thermostat will be closed, allowing coolant circulation around the engine block and cylinder head but not through the radiator. Only when the engine has reached normal operating temperature will circulation be noted in the radiator. A good test is to remove the thermostat while the engine is cold , start the engine with the radiator pressure cap removed and observe flow. If as I suspect it is there, refit the thermostat and check the heat gauge. If all remains well there is no problem. If the engine overheats replace another thermostat. If there is no circulation with the thermostat removed, there is a blockage in the cooling galleries of the engine. If chemical flushing does not clear it, it will require disassembly of the engine with careful step by step inspection at every stage. If the cylinder head(s) had been removed I would suggest making sure of the galleries not being blocked by installing the gaskets incorrectly. Regards John

93 saturn over heating


Mr. Johnson,just for your information a car to overheat is not only fan and radiator,there are more things like the below I will state and check.
THERMOSTAT whether stayed close,WATER PUMP might the propeller is worn and does not circulate the water,- to confirm about is to start the car without thermostat but full of water and rev it at about 1500 rpm and follow the expansion tank whether the water circulates.- RADIATOR FILLER CAP whether is the correct with the manufacturer recommended pressure, MATRIX whether is open and allow water to circulate-check the hoses of it whether are getting hot similar to the radiator heat hoses.RADIATOR is it clean inside from any mud-check the vents outside having the engine off and touch all the surface- must have the same heat allover the surface.EXPANSION TANK hose connected with radiator whether is open and not blocked to allow water to move.FINALLY if everything is okay and you still have the same problem then is unfortunately either compression gasket or cylinder head.One last advise `before you go for the worst please check also your valve clearance whether valves are not tight and forcing the engine on driving.Good Luck and let me know what happened.

Even after replacing the radiator, thermostat and


The problem with overheat is due to poor coolant circulating. The main culprit is the Radiator. When the radiator is clogging up, coolant can't be circulating. The stagnant coolant inside the engine water jacket keeps absorb heat from combustion chambers having no way to dissipate the heat then the engine is overheated. You can test the water pump by removing the thermostat, then hooking everything back. Open the radiator cap, then turn on the engine to see if water flowing down to several small tubes inside the radiator. If water can't go down fast enough to cause over flow at radiator opening then your 90 Legend Radiator already got clogged up. Replace with a new radiator, not even a rebuilt one. Good luck.

I removed thermostat to allow radiator cleaner to circulate system. However after driving for 10 minutes the temp gauge reaches the red mark,what could be wrong Thanks PaUL


The reason it is still reaching the redmark is because without the thermostat in the vehicle it does not give the water in the radiator time to cool down before it is sent back to the engine. Reinstall the thermostat and refill the system. If the vehicle still overheats the water pump is probably bad and not circulating the water appropriately. Also make sure the fan clutch is working correctly, You can spin the fan blade and is should not go more than 3/4 of a turn before stopping, If it spins more than one or two complete turns you might want to replace it.

2001 Jeep Cold RAdiator


Does your temp gauge read normal? if it does then the thremostat is ok,but sadly the water pump is going bad this is typical of jeeps at an idle the heater cools off because the water pump fins are worn enough to not circulate through the heater core and when you step on the gas the increased rpm move the water fast enough to circulate through the heater,it is possible that the heater core is plugged but I doubt it as a plugged heater core would not get hot either it would be cold or just luke warm all the time.

Water pumps can stall out, but do you have air trapped in system.
Had you recently had the system "open" to replace hose, thermostat, temp sensor. Some Ford and GM have a bleeder screw on a high point in cooling system to bleed out trapped air.

Check your trans fluid color. Since the trans cooler is built into radiator (automatics)

IF the engine is overheating the trans CAN overheat
IF the trans is overheating the engine CAN overheat

They share the same cooling source and trans fluid gets hotter than oil, but yet it has a wimpy cooler built into radiator. Maybe add trans oil cooler to system.

Also outside temp affects the cool down rate of the radiator, ie...hot air trying to cool down hot radiator/engine is less effecting than cool air cooling hot radiator/engine
