Possibly head gaskets which are difficult to repair correctly.

Run strong still no power lost


Do you notice any white smoke coming out the tail pipes on the initial startup? Or possibly a slight engine miss that goes away after just a few seconds? Coolant in the oil or oil in the coolant, all of the above are sure signs of a blown headgasket. And yes they will still run very strong until they blown completely out. Other things could be a bad thermostat, restriction in the cooling system, blocked air flow through the radiator, inoperative cooling fans. HTH


Try a full cooling system service - new hoses, flush, t-stat and coolant and make sure the cooling fans work properly. You may also need a new radiator if flushing does not bring the temps down.
