This one came in because it leaks coolant. I already tightened a clamp under the tank that was "peeing" coolant down the back of the clutch cover. Also, already tightened is the large clamp under the right head. Hopefully after these, the 3rd and 4th leak, chasing coolant leaks will end. His cap failed its pressure test also, so it'd be nearly impossible for him to know about them. Just an FYI ... a cooling system not holding pressure has lost upto 55 degrees of boil over protection.
