Hey all,

I've been having a problem with my efans, Whenever i run my ac in stop and go traffic my engine starts heating up. I parked and open the hood to find out one is not working at all. Now i thought that it was a bad fan but on other occasions the fan works fine (when i checked the ac was off). I've also noticed that I'm getting around 10-11 volts with the ac on. Now i bought the overdrive pulley for the alt but I've been lazy and haven't installed it. My question is could the lack of power be causing the fan to not work at all/relay not open?

Thanks again.

 

the relays are good? when you turn the ac on the fan(s) should come on high, no matter if its a cold start or youve been driving for an hour.

i had a problem with where my A/C relay was connected to and it would over heat the relay and shut it down. rewired it and bam, its good to go.

 

Will check tomorrow.

 

Well, both fans came on but not it didn't look like high. It took a second for them to turn on but they looked low. I let the engine idled to op temp and it sat at 207 degrees.
