Answer
Hi Bob,

The most common cause of overheating is air trapped in the cooling system. When we service our MC's and replace the coolant, we usually get air in the system. The air must be purged from the system or the coolant will boil at a lower temperature and overheat as a result.

I use this tool to service cooling systems. It simple to use. This is an investment and money spent wisely. See the Mityvac Air Evac tool at the following link:
