Someone is trying to prevent me from taking the family in the GMC for our trip! As I mentioned earlier I wanted to give the stop leak a try. So after Church I got some Bars "Liquid Aluminum" and poured some in. I could only get 3/4 of one bottle in because the rad was top offed. So I figured I would warm up the engine to get the coolant circulating purging any air out and freeing up some space in the radiator. After about 4 of 5 minutes i went to kick the choke off and noticed the engine temp was at 3/4 mark! Yikes! I shut it down of course and couldn't believe it was over heating. I felt both upper and lower radiator hoses and you could hardly put your hands on them so no doubt it was hot. So I'm think what could possible causing that?
Thermostat is opening because the upper radiator hose is hot from the thermostat to the radiator. I was thinking the radiator has a block in it but yet the lower radiator hose is also very hot however mostly on the upper part of the hose and not where the radiator hose attaches. In fact the cold area starts in line where the radiator shop soldered. The last five or six rows are cold.
Is that area cold because it is at the bottom and has not yet circulated through? Other than the radiator what else should I check to be sure? It does seem obvious the radiator is the culprit but just not sure of the failure mode.
Guys what do you think? I'm desprite. Our vacation in our GMC is fading fast! The idea of taking our minivan is nauseating.
