why won't my radiator fans engage
I need help with a 2010 Chevy Silverado radiator fans issue. Engine temp is 210F when on highway. Tranny temp sits at 140-165F as well, climbs to 190 in traffic.
Replaced the radiator since it cracked this past february but ever since then the fans no longer engage at higher temps.
swapped the relays on the Hi, Lo, and the Fan switch, still won't engage.
Change the cooland temp sensor to a new one, nothing.
Changed the thermostat and still nothing.
The only thing that is keeping is cool is disconnecting the Temp sensor to leave the fans on "direct" at high revs.
My ac doesn't work if that could be the cause of the problem, or if it would engage the fans.
Any help is greatly appreciated.
don't know if this will help but on my van, i'm running a 160 degree thermostat and the engine runs cool and fine.
