Having problems with your 1983 AMC American Motors Concord ?
79 cj-7 258 overheating.....help
\015 The 258 has 12000 miles on rebuild. Moter overheat real fast not matter what.. New thermostat,water pump,head gasket and just put in block-head sealer.....no help\015
That block head sealer is what's causing the problem. Most likely it has coagulated at a prime spot and plugged up the water flow. That stuff can make for bad flow restrictions. I would reove the lower radiator hose and connect a garden hose to it and turn the hose on to back flush the engine. Leave the water run for a good while and see what comes out of the upper hose you disconnected from the radiator. You don't want that trash going back into the radiator and plugging it up. Back flush the radiator seperatly.
