Another quick indicator of cooling system health is the length of the water vapor trail at the exhaust outlet. A foot or three of white vapor is normal at higher RPMs during a normal summer day. If it grows longer than say 5-10 ft or so before disipating, the reason is the water is leaving at a higher than normal temp and needs to be investigated. Cool, damp weather days also cause longer plumes.
