Is my radiator dead my thermostat or my water pump?

Asked by Jan 09, 2015 at 04:55 PM about the Chevrolet S-10 Blazer

Question type: Maintenance & Repair

It's a 96 s10 chevy blazer. My heater
went out a couple days ago, and was
close to overheating, so I added
more coolant to the radiator and
fixed those problems. But my
radiator is cold. I think it's the
thermostat but a buddy thinks its the
radiator altogether. Which would it
be?

thermostat first always
