In the process of replacing radiator, fan clutch, water pump etc. Here is the fan-side of the radiator. Quite a bit of smashed fins. Do you think that is enough to cause my overheating issue? The pics don't really do it justice either. I'm replacing it anyways, just wanted some reassurance that I'm heading down the right path.
I took the truck for a drive and let it heat up to operating temperature. I did the test and had no change in fan speed. The newspaper didn't effect it.
Thanks for the responses. No bling added to my truck, its as stock as can be. It doesn't have and issue with temperature unless towing uphill. I took my grill off about a month ago and cleaned off the radiator and condenser with compressed air... didn't make a difference though. I'm having to pull over sooner and sooner to let it cool off. I've reached in and tried spinning the fan and it seems really tight and barely spins. I will test some of the above mentioned and see if that helps.

My Silverado is getting really hot while towing up hill, to the point that the "Engine Coolant Hot" light is coming on. (Which I stop and let it cool down). This has gradually gotten worse. Truck does not get hot while towing on flat terrain. Any ideas?
