i have a b16 Rex i was driving my car the other day and i braked downshifted and took a turn i saw my temp gauge go all the way to the high and all the way down it started jumpin up and down so i checked it out no leaks that i could see so i searched the net i tried the air bubble thing i also checked my thermostat i it works fine im stuck i dont know what else it could be

thanks

 

check for radiator fan if its tuning on

 

yeah it does i have to turn it on by a switch

 

No, but when the temp guage is almost at half

 

yhea its almost always on

 

almost??

 

i dont turn it on when its heating up its a weird set up the fan wires are connected to a switch inside the car that i have to turn on

 

oooh, ok.

 

got any ideas of what it is

 

dose the car feel hot when the guage show hot
