    To find the leak, you need to do a radiator pressure test. You can get a pressure test kit pretty cheap at Harbor Freight. This will show you where the leak is; if know leak is detected, it very well be the radiator cap not getting a good seal. I'd check these before replacing the thermostat, simply because it may not be the thermostat.

You could do that in fact I've done it a few times myself to either rule it out or pinpoint it as the problem. Your top radiator hose will lead from the radiator to the thermostat housing take the housing off and there's the thermostat. Personally I would take the thermostat in the house put it in a pan of water and see if its opening and closing right without any hitches. Also if the fan(s) aren't working properly they can cause it to hiss and spray through the radiator fill. I would make sure to test the thermostat although you don't know at what temp it opening you'll know it is opening. depending how far you live from a parts store I would drive it there and back without the thermostat the install the new and drive it the same distance to make sure it not going to overheat. each time you take the thermostat housing off you have to clean as much of the gasket and sealer as possible on both the side that connects to the radiator and the side on the block. Everything it cast aluminum so be careful not to torque it so hard you snap the bolts off. Good Luck I Hope This Helps

    Samsung pad2\'s got a hair trigger. what I meant was borrow her thermometer for boiling hard candies, cuz thatl measure the exact temp of thermostat o/closing.

    Yeah cleanspit64......that will work well providing he can get the temp rating on the thermostat so he can watch the candy thermometer and see if it opens at the proper temp. It would be so much easier to diagnose I we were there.

It's almost never a pcm. You need to check things like the fuel pressure when this happens. I'd take it to a better shop as alot of tests require special equipment.

It sounds like the water pump is not working. Google your make and model with the words 'water pump repair' after it, if you want to try repair yourself. Otherwise take it to a mechanic you know and trust

2000 dodge ram hissed and sprayed antifreeze when drove home. Filled the radiator, once it cooled down, but NO leaks? Should I pull thermostat out and test it? If so, show me how please? Or what do I do...


Sounds like you have a leak, otherwise you shouldn't have had to add fluid. Thermostats are often blamed for overheating but rarely are the cause. My first step would be to pressurize the cooling system and look for a leak.

99 suburban leaking from oil cooler fitting on radiator


It sounds like you might have a crack in the plastic tank of the radiator. If the line was leaking, I would think you'd see some oil leaking. Any anti-freeze leaking? When the truck is cooled down, I'd check the anti-freeze and oil level.

I have a 1999 dodge ram with 171k miles on it. just recently i noticed the traqnsmission slipping i checked the fluid and it was low. i added the fluid it helped for a little while but then the same thing...


Yes, it could be leaking into the radiator from transmission cooler in the radiator. I would flush as much of that out as you can and replace the radiator, the anti-freeze is very damaging to your transmission.
