Best Answer

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....

How do you fix overheating on a dodge Ram 250 van?

I'm not a mechanic but, I had to replace my radiator to fix the overheating problem on my 1994.

Flush the coolant first then replace the radiator. Hope this helps.

Why is your 2002 Chrysler Town and Country overheating?

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.


Mk 2 overheating tried loads inc new rad why still happening?

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.

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.

Why does a ford temp overheat when you first start it?

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.
