    yeah its over heating but it seems like the water is evaporating engine. and what i mean about the hoses being open is their not cloged or anything

  • Anonymous Dec 02, 2008

    my maliby started over heating, replaced the thermostat, ran for a while, started knocking and the water would just evaporate. friend thinks it may be the relay swiches for the fan or water pump, dont know but water just disappears

    Ok allencary, I have more ?'s for you. Is the water leaking out anywhere when u fill it cold, and not running? If u drive it, how long before the temp gauge gets to the overheating zone? How does your oil look? White-ish milky color? Has oil level gone up by any chance? (would indicate possible blown head gasket). U say it's overheating, is there steam coming out from under the hood? Where exactly? The more info the better! What engine, and miles on car?

    Do you mean it's overheating? What do u mean by ' all the hoses seem to be open'?

98 ford ranger over heating problem i change thermastate already what else can I try


Check out the water pump.

Feel the hoses. If one is hot and the other warm / cool and you've installed the thermostat properly (not backwards!); I'd suspect a failing water pump.

Coolant leak


It is possible that the housing for the water pump has corroded and the new(hopefully) gasket is unable to seal off properly. Water pumps have a bleed hole underneath before the bearing so that in the event of the seal leaking the water will run out and not affect the bearing. May be the housing was not cleaned properly and a piece of old gasket is preventing the new gasket for fitting properly. If you have doubts that he did the job go back and front him to get the job done properly. Remember that in future the replaced part is yours and you have rights in law to take the old part home with you to prove it was changed.

Could be a problem with the radiator its self, or you have a blockage in the hose coming from the radiator to the thermastat. You might also check the hose from the radiator to the water pump or the water pump its self.

I have a problem with it over heating ! I put a new rad. New thermastate in it even change the cooling temp. Senor ! But after all that the damn thing still overheats what can i do to slove this !


the problem may be the water pump,as you have changed everything else that is all it can be,but before you replace it check the bottom radiator hose to make sure it has not gone soft, sometimes when this happens the bottom hose will flatten when the engine is reving not letting the water circulate.......hope this helps..........cheers

Overheats gets hot on the top of the motor but at bottom hose from thermastate it is cold changed radiater and put in two thermastates still gets hot help


1. In order to eliminate, remove the thermostat altogether, for now.
2. Make sure the heater bypass hose is working. You could route the hose going into the interior heater and bypass the heater also.

It should eliminate a lot!

Next, consider the water pump.

Hope this helps!

Coolant leak from upper radiator hose where it meets engine


thermistate housing is the place you refer to it fuction is to hold a thermastate to open and close water flow at 150 to 190 degree according to car spectif the thermaste sticks it causes overheating and can blow the thermastate gasget, the tole cost is about 30$ at most for the thermastate and gasget...now many other things can cause a car to over heat and cause a hose leak and somtimes it is simple to just tighten the hiose clamp at the thrmastate and problem sovled see a water leak causes the radiator to lose presure and thus with out a sealed tight water cooling system the boiling point of water is lower and thus the car over heats when in doubt stop by the local gas station and have a tech take a quick look as it could be simple as the hose clamp difficult as a therm,astate but do not let it go to warp a head gasket as this blown headgasket is what is the end results of running a car to hot
