Only try to "figure it out" if a leak develops. The head may have warped but will/may hold its shape as long as it is bolted down. In other words - if it aint broke dont try to fix it. > o How to figure out why he was havign overheating problems to >begin with? Water pump failure?

The first thing that I would check is the actual coolant temperature using a thermometer - a candy thermometer should do fine. The car may be the victim of a faulty sensor/sending unit/guage. Check to see if the coolant is flowing through the radiator. Turn the heater on, does it provide a steady flow of hot air? NOTE: If a car is overheating, turning the heater on can reduce the engine temp by as much as 15 degrees F. That heater coil is nothing more than a mini radiator. -- A question is better debated and left unanswered than a question that is answered without debate. -Unknown
