Newbie with a question!

Over heating doesn’t necessary mean BHG, other things could contribute to over heating, thermostat, water pump, radiator condition, to name a few. The first thing I would do is a block test Link . If the gasket has failed then a re-torque after 20K would only be a temporary fix, if it did worked at all. I replaced a head gasket on my first Supra many years ago, drove about 15 miles down the road only to find it over heating again. The bock test shown negative, so I decided to pull out the water pump, only to find the impellor had disintegrated leaving only one impellor blade. The problem with an over heating Supra is that we get paranoid about head gasket failure, fortunately in some cases it’s not always the issue.
