Sometimes air bubbles get in the radiator after lines or the radiator have been removed. Just run it with the radiator cap open, until the fluid starts circulating ( the temp gauge will drop to normal). You can also see the coolant fluid start moving inside the radiator which by the way is a little hard to see since it will be bubbling from running about ten minutes. Watch your temp gauge make sure you don't let it overheat for a very long time. Did you put it in backward? There really is a right and wrong way on those things. no, it wasnt put on backward.... ============================================================================= no, it wasnt put on backward....
I had replaced the water pump and radiator. This had continued to overheat but not as bad. After replacing the head gasket it was finally fixed. I was able to answer my own question only after replacement.
I'm not a mechanic but, I had to replace my radiator to fix the overheating problem on my 1994. That was the last thing I replaced after replacing the water pump, thermostat, and replaced my fan with a clutch fan. have not had anymore problems with it overheating once the radiator was replaced. Flush the coolant first then replace the radiator. Hope this helps.
A bad radiator cap needs to be replaced as soon as possible. Fluid can leak out causing the car to overheat. Constant overheating can lead to expensive repairs. The average radiator cap costs less than $10.00, so it's worth the investment.
Is your fan coming on?
i would have replaced water pump long before replacing radiator. also check engine oil to see if it has engine coolant mixed in.if it has then the problem is more likely to be a bad head gasket
Blown head gastet, radiator leaking, thermostat needs to be replaced Blown head gastet, radiator leaking, thermostat needs to be replaced
There are numerous things that can make a car overheat. It's possible the coolant level is too low, or the electric cooling fan may have gone out. Another possibility is that the thermostat may need to be replaced or the radiator fan switch may not be working right. The car will also overheat if the fan belt is broken or if the radiator is plugged up.
Overheating can be due to several factors. You could have a bad water pump. Check for slight steaming from the water pump, sometimes unnoticable if it's just the seal. Also, it could be a bad thermostat, which if it stays stuck shut can cause overheating. Another factor that is not the radiator is the most costliest of the repairs. If the head gasket blows, what happens is that the car will continue to overheat even if you've replaced the radiator. The loss of compression in the engine causes the car to continuously overheat.
One reasons a Subaru Forester may overheat is because the radiator may need replaced. Another reason could be the thermostat.
IF IT WAS NOT OVERHEATING BEFORE THE HOSE WAS REPLACED -- MORE THAN LIKELY YOU HAVE AIR POCKETS TRAPPED IN YOUR COOLING SYSTEM
Inoperative radiator fans, bad water pump, failed headgasket?
Water pump defective.
your thermostat is closed. needs to be replaced. inexpensive part but can save your engine from overheating.
If you have replaced the water pump then flush the radiator with CLR also check to see if the fan is working properly.
Check the relays in the small relay box UNDER THE HOOD. There is a relay that will go out that runs the cooling fan when the car reaches a set temp. If that fan does not come on then it will cause the car to overheat. If that turns out to not be the problem have a mechanic look at whether the head has warped from overheating.
Reasons your 1999 Honda Accord is overheating can include a leak in the water hose, a blown head gasket, or the radiator cap needs to be replaced.
If you replaced some of theses already ignore and go down the line # Not enough coolant # Water pump drivebelt defective or out of adjustment # Radiator core blocked or grille restricted # Thermostat faulty # Electric cooling fans blades broken or cracked # Radiator cap not maintaining proper pressure # Ignition timing incorrect
my niece's was overheating I replaced the radiator cap and it hasn't happened since FYI
Even though you have already replaced the thermostat, there are other issues that can cause your Nissan Maxima to overheat. Your fan may be stuck and not operating as it should.
Possibilities: Cooling fan not working. Low on coolant. Clogged radiator, radiator hose or block.
It is probably your fan. Check and make sure your fan is kicking on. Jeeps tend to have problems with their fans not working. If it does not overheat when you are moving but it does when you are sitting still then it is probably the fan.
You need to go get your car looked at by an auto repairman if you have a crack in your auto radiator. They can tell you if it needs replaced or just fixed.
Most of the time it is because the thermostat has gone bad and is not opening at the proper temperature. Cure: replace thermostat. If the thermostat has been replaced, flush the radiator. Buildup of residue in the bottom of the radiato0r will cause overheating, but it is maintained over heating, not temporary.
radiator fan, head gasket,
Have you replaced the heating core yet?
