Cooling fans on high 5 sec after startup
I have a 2007 Silverado 1500 classic 5.3 4x4
5 sec after I start the engine the radiator fans kick on high speed until I shut it off.( It sounds like a jet) I have replaced the temp sensor and the relays in the hidden compartment next to the fuse box for the cooling fans and still no bueno. Any suggestions would be amazing
Thank You

My 2016 F150 V8 had a very loud fan and I changed the pressure switch and thermostat. Neither helped. I took it to the shop and my high pressure freon read 300psi when the truck was off.
