my car was overheating and i got water steam coming out the tail pipe

so i changed my head gasket to a brand new one and i just finished the job

anyhow now the car stilll overheats but no smoke comes out the tailpipe. i think my water pump is bad but i dont know how to check it. The car will overheat after about 15 or 20min. its funny too because the fans on the radiator are not coming on when it does overheat but when i turn off the engine the fans turn on. This is awww annoying

somebody give me some advice

 

Have you done any other stuff ... bleed the cooling system, make sure the coolant water mix is sufficient, check the thermostat, etc.??

 

how do i bleed the cooling system. i just watched it as i left it in neutral and filled it up while it was on.

it has a brand new thermostat

 

umm, when my cousin changed his thermostat it didnt cool right for a while, then it magically fixed itself and now it cools fine for some odd reason.

 

well shit its been a week of testing this crap and it still doesnt cool and the fans dont turn on when the cars hott

but when i turn the car off the stupid fan turns and cools of the radiator

 

Make sure the radiator is full and there is coolant/water in the overflow tank. Take the cap off the radiator. Go in and start the car. Turn the temp all the way up on hot and turn the interior fan on. Let the car idle like this until the radiator fans kick on twice. Any air in the cooling system will work its way out to the radiator cap. Shut the car off and cap the radiator. On your next drive, see if the over heating problem persists.

 

you know what it is

the stupid fan on the radiator just wont turn on
even when it gets hot while the car is running the fan will not turn on and cool the radiator

if i turn my heater on fullblast the temperature will go back down to normal.
if i turn my car off the fan will turn on and cool the radiator off


does anyone know why the radiator fan will not turn on while my car is running and it goes hott. i checked all my fuses and they all look good

i cant make sense out of this

 

make sure your fan is plugged in. also check the temp sensor on the front side of the head where the radiator hose is

 

damn im so stupid when i changed my head gasket i forgot to plug in the fan relay switch that turns on the fans when it gets hot

now it works great

my bad hahaha
