Fan constantly running

[Kylebg94]

So I have a 95 silverado k1500. Everytime I crank the truck. Within the first minute, the fan turns on. And stays on the entire time the truck is running. Is this normal for these trucks or not?

Engine fan?

When a new fan clutch was installed by the GM dealer on my father's K1500 '95 5.7L, the fan would run all the time until the engine RPM got to around 3000, then the clutch would release and the fan "spin down" to something more normal... at least, while cruising down the road. Upon slowing (engine RPM lowers), the clutch would engage again and remain tight until the engine RPM was again over ~3000, then it would release.

Rinse and repeat.

Electric fan or viscous fan?

Cab blower or radiator fan? Or auxiliary fan?

It's not electric. Sorry for the late response. I had alot going on in the past few months.

The two main fans that help with cooling. So a radiator fan

Radiator fan has a thermo viscous fan. Yes it runs on start that's normal. As it gets to operating warmed up. It will modulate it's speed depending on temp.

I read that was normal. Awhile ago. I've been having quite a few issues here and there with the truck. So I've been getting a little paranoid I guess.

If you download the OE service manual, it not only has repair and diagnostics, everything also is covered with descriptions and operation explanations. " That does this, and this is why it does that." If you got half a brain the systems descriptions are in plain English, not algebra.
The eng section has links to download the free PDF for your year truck.
