ok i have a 88 dx hatch with a d16a6 swap and it overheats,i changed the thermo and still overheats i looked in the archived articles and was just wondering if anyone could give me another suggestion.i think there is air trapped in there somewhere when i let it sit it heats to normal temp and i can drive it for a little while then it will start overheating when it doesnt overheat i have heat from my vents but when it overheats i get cold and and the top hose is hot and the bottom is cold..any suggestions would be nice....thanks

 

that sounds like there is no flow, so I am thinking water pump or thermo

 

another thing i forgot to add was when it overheats antifreeze spills out of my overfill.....

 

Does your fan work?

 

yes my fan works fine

 

sounds like a headgasket take it to a shop and do a leak down test and have them remove the rad cap and if the coolant and water flows out of the top you have a blown headgasket

 

yesterday i took my thermostat out and ran it for about a 1 hour without it and it didnt overheat and i put a new thermostat back in it and it started overheating again.....i dont know if that will help anyone figure anything out im stumped....

 

take the thermostat back out and take back to the store you order it from and ask for a new one

 

ok i think im just gonna go get a oem one from a dealer and also i think there is air in my cooling system so im gonna flush it out.....

 

Radiator could be clogged or you might have to replace your radiator cap. the spring rate on it might be weak?? Or if you want to check if the head gasket is blown, check your dip stick and see if you have coolant mixing(chocolate flavor)or if you run your motor to operating temp and slowly remove the radiator cap and you see alot of bubbling, you probably got a blown head gasket. hope this helps. good luck.
