View Full Version : cooling fans...

Sorry if this is a repost times a billion but i didnt want to try and revive a year old thread for new answers...

Car is a 99 GAGT 3.4, cooling fans dont turn on by themselves
if i turn on the ac they kick on what seems like low speed, turn the ac off they stay on low.
At an idle the car wants to creep up, i dont let it get more than 2 notches above 200 before i do something about it, so im not sure how hot it would get.
BUT anyway, besides the fact that gm designed the fans to come on at higher temps for emissions reasons why dont they come on? and how do i fix it, before i resort to caspers.

I just finished the LIM gaskets about an hour ago, replaced water pump, thermostats, all new fluids, all hoses are new, now i just have to fix this. Seeing as how my hvac only works on 3-5 im sick of using the hvac to cool the engine. HELP!

I have two questions for you...

1. Did you properly bleed the air out of the system after you did all the cooling system work?

2. Did you read this post?

And since you mentioned another common issue, I thought I'd go ahead and include the info for you on that one...

...that link should take care of you fan speeds not working.
