to make sure the temperature of the fluid in the radiator is cool enough
Chevy, Camry, Corrola, Chrysler, Corvette
check the battery and connections/cables
You do it very carefully so that you don't break your car
YES THEY DO THE HARD TOP DID NOT START FOR SEVERAL YEARS
All I need to know when Chevy started and why?
Turn the AC or the Defroster off.
A lot of the time Chevy used aluminum battery cables in their cars,(in particular my 1980) I was continually having starting and battery problems until I replaced the cables with copper.
The radiator cooling fans are turned on when the heater control is set to defrost.This makes for better and more effective defrosting of the windshield
it will be on one of the lower corners of the radiator. When you find it turn counter clockwise a few turns, then pull it out some and the water will start coming out.
fill the radiator full, DO NOT CAP THE RADIATOR ! Start the truck, allow it to warm up, allowing the thermostat to open up. While it is warming up, keep topping off the radiator. Once it is hot, and to running temperature, cap the radiator.
Drain the blazer radiator. Refill with water. Open the heat on high, start the engine for a few minutes. Drain the system again Repeat this several times to get all of the old coolant out.
My Chevy was doing the same thing. It turned out that the connectionc on the starter were getting wet and arching. check that the ceramic shiled is fully intact AND THAT THE WIRES AND CONNECTIONS ARE SECURE TO THE STARTER.
