engine running rough after overheating
battery had to be charged , so let truck idle to recharge, after awhile we noticed it was
running hot, now engine is running rough
how hot???? did anything get wet....is the alt charging so it not running of the battery?
Today's alternators are not designed to recharge a battery, it overheats them and burns them out, always use a battery charger to recharge a battery,a trickle charger is the best and do an overnight charge. If the engine ran too hot it can cause stuck valves, loss of temper in the rings, engine cylinder wall damage and they turn blue. The best thing to do is pull the plugs and run a compression test on each cylinder, if you some that read low then the heads will have to come off to see what happened during the overheat.
