Part Three: Cooling System
Before going out and flogging the truck, there were a few more things to tackle. One thing I noticed when driving this truck was the temp gauge and how hot it ran. Cruising down the highway, under light throttle, the temp was in the realm of 240 degrees, way too hot for a truck with a 195-degree thermostat. I called Grandpa and asked if the truck always ran hot, and he said, "I had a small leak in a freeze plug, so I poured in a few bottles of stop-leak." Well, there was my answer: Stop-leak products work great but only when you use one can. The new replacement radiator I got from LMC and the Prestone Flush should take care of this issue. I'm going to change the thermostat and the radiator cap, just to be on the safe side.
