Rule No. 1. Never believe your gage's unless they have been calibrated.
Rule No. 2. Unless you blow-down under operation (looses coolant as your
driving) your probably NOT overheating.
Rule No. 3. If you loose coolant after shutdown, you probably have a
pressure leak in your system. Likely the pressure cap. Most
tigers will
run a 15 psi cap without problems, but you may find that the
heater core
has expanded into the walls or will fail if this is a "new" higher
pressure. Fix the problems and run the higher pressure cap.
Rule No. 4. If you run very hot in slow traffic, the most likely problem is
recirculation of the air that has already passed thru the
radiator. A
more effective pump mounted fan (more CFM) can help, as can a
supplemental electric fan. The real need is to close the
recirculation
paths around the radiator.
Rule No. 5. Any pump mounted fan is only effective if it is surrounded by a
fan shroud. If yours is missing, find or build one.
