i just got a 92 firebird vert 305 tbi on the way home it got really hot i pulled over to let cool down then went on home put new t-stat in a 160 still runs hot decided to check fan took it out ran jumper wires to it it works has plenty of coolant cant get fan to come on when in car fuse is good checked that after i put fan back in car started the engine and fan kicked on until car got warm then kicked off then would not come back on looked for loose ground didnt find any dont know where to go from here had some friends tell me to run fan off a relay to a switch in car but not sure if i want that or not would rather get everything working the right way any advice or help would be great

 

i ran a constant to my radio fuse. so my fans always on when the car is on

 

ohh yeah and now when the car is running at idle it starts to smoke a white smoke but if i take it to around 1500 to 2000 rpm it clears out and is fine for a lil while just wondering what that could be

 

maybe antifreeze leaking from the head gaskets. thats my guess

 

would that cause it to run hott

Read the whole thread, had the same problem. I'm almost certain its the coolant fan motor switch on the side of the block located under the passenger side manifold.

 

well put new fan switch in but still didnt fix it is there anything else or should i just run the fan with the ignition??

 

these cars don't really run hot, unless stuck in traffic, on the highway they cool down with only the wind. I'd check to see if the water pump is pumping and coolant levels, if you've not done so already. My stock 305 never got very hot unless in traffic with the air conditioner on, in Fla. And like the previous post said, the white smoke could be coolant in the combustion.

 

but wouldnt the coolant get in the oil then cause im not getting that im just wondering why the fan wont come on

 

A cooler thermostate wont fix that you either have a radiator problem or engine fan problem. You could have a clogged cooling system, bad head gasket things liek that.

 

i have a fan problem it wont come on ive tested the fan it works put new switch in and checked the fuse the only thing i havent done is change the relay

 

If you look at the relay and understand basic electrical diagrams, you can jump the terminals and test to see if the fan is works there, by testing here you can rule out the relay as good or bad. They commonly fail, and sometimes appear heated up or burned where excessive heat has been building up.

can you tell me where the relay is for the fan or maybe a pic of one

 

The Technical articles section on here has complete info about how your fan system works. The relay is one of the two on the driver side firewall by the brake booster. If you ground the wire that connects to the fan switch either near the switch or at the relay with ignition on, the fan should go on. Also if you turn on AC switch it will go on if relay is good. If not check relay

 

well got the fan to work it was the relay but there was 2 burned places on the relay and the plug what would cause that to happen

thanks for all the help and for being patient

 

my car was geting hot when i drove it it was the air dam i would check the air dam will not stay cool without it
