wat 1 under the hood or the 1 under the dash

 
Rep Power: 229

both.. im not sure where it is exactly on our cars.. but 90% of the time that the fans dont kick in r becuz of the fuses.. i think the ones under the hood.. check those first

i check it and it good idk wat else is it damn it killin me

 
Rep Power: 229

u checked both??? under dash and under hood??? then check ur connections... u noe how to check that??also both fans aint working??? or just one??

 
Rep Power: 0

i think both because wen i turn the heat on no fan come on and wen i turn the ac on nothin

the fans do not come on i do not hear them at all maybe it the thermostat sensor that y my fans do not come on

 
Rep Power: 229

it cant be ur thermostat.. cuz ur car would automatically overheat... once a thermostat goes bad.. it stays closed...now is ur car overheating right now??? did u leave it on for like 20 mins and check if it overheats?? did u check ur fan connectors??

 
Rep Power: 0

it do not overheat wen i let it run 4 20mins

 
Rep Power: 229

then ur fans r working the only thing is dat the fans on our cars rarely come on specially wen its cold out..

so wat can it be then i just picked my mom up and it did not overheat at all

check the fan relays (the small boxes in the fuse box). maybe they went bad. it is getting colder now too^ so you dont need the fans as much for cooling as you would in the summer.

0 ok i c 2night if it overheat wen i go out

Damn bro still havent fixed this? Maybe it is ur coolant temperature sensor that is not making them come on? I believe once that reads a certain temperature it kicks on ur fans. I am in NY and I have one u could use to check it with if ur close by.

theres actually a second sensor for that, called the radiator fan temp sensor, its right next to the ect (engine coolant temp) by the thermostat.

 
Rep Power: 0

idk i think it is the sensor but i really really think my radiator got a hole because wen i pop the hood is was coolant ever wear on the motor it overheat wen i beat on it that it and then i c mad coolant ever wear !!!!

 
Rep Power: 254

ah ok I confused the two but thats the one I meant. If ur getting coolant everywhere I would check the cap.

could also be overflowing from the reservoir. try a new radiator cap.

In theory thermostats are designed that if they fail they fail open to avoid overheating.

 
Rep Power: 812

ive seen cases where a thermostat has been stuck open, closed, or partial open.

 
Rep Power: 219

Yeah my wifes old 93 civic the thermostat stuck closed and by the time I got out and realized the car was overheating I checked under the hood and the end of the radiator hose on the3 top end of the radiator was the size of a baseball!

That why I said theory

the fans arent seized are they? spin them by hand, our u could temporarly straight wire them to see if they kick on, good luck

Well I think I finally figured it out in my car. My fans dont kick on at all since its so cold out here unless the a/c is on but I just waited till the engine was cold and ran it with the radiator cap off and kept filling it after the bubbles until it finally stopped, and then after it reached operating temp I put on a glove and squeezed the bottom hose a little so any air left would come out, and then I revved it, kept it revved, waited for the radiator to suck the fluid down, kept it revved, filled the fluid to the top and put the cap on. Ever since, no issues.
