09 Silverado Overheating

Topic starter

Hey Scotty, big fan by the way. My 09 Chevrolet Silverado with 150,700 miles with a automatic transmission. It started to overheat the engine and trans every time the trans goes over 180 and I’ve replaced the Engine coolant,thermostat,engine coolant temperature sensor, and now going to replace the coolant reservoir cap. Plus when I went and check after replacing 3/4 parts, I saw that the fans didn’t kick in so can you help me out?

You will need to check for voltage on fuses FAN1 & FAN2

and these relays: PWR/TRN , FAN LO, FAN CNTRL, FAN HI

do you know how to test fuses & relays? Do you have a test lamp or multimeter?
