Engine Fan or Electrical Fan
Quick question. I have a '71 Blazer with a 454 that overheats when not moving. I'm working on getting it back on the road and want to eliminate this problem. Should I go with an electrical radiator fan in conjunction with the engine fan. Or should I have just the electrical fan? Can the electrical fan be tied the thermostat or will I always have to switch it on? I don't like the idea of having to flip a switch each time I drive it as I know I will forget? Looking forward to your advise!

I think it is pretty standard set up to have an electric fan with a relay controlled by a temperature sensor.
Does your mechanical fan have a shroud? Adding a shroud can make a big improvement if you want to keep things simple. I learned this lesson on my 68 Mustang.

Firstly, what have you done maintenance-wise? Thoroughly flushed the coolant system including the heater core? Installed correct amount of coolant mixture? Replaced the thermostat? Replaced the radiator cap?
