74″ THERMOSTATE VALVE (C-4) (J-5)

This is the lowest temperature stock thermostat, ideal for hot climates or

summer fitment with 82 degrees for winter, the ideal temperature commensurate

with optimum power output is 65-70 degrees. However this is not practical for road

applications. The lowest thermostat available is 75 degrees and should be the lowest

one considered. 82 degrees is a much better choice with an 88 degree alternative for

winter driving and those with economy as the main consideration. The higher

temperature the more thermally efficient the engine becomes. It is possible to run

thermostats with the troublesome bypass hose blanked off by drilling a couple of holes

1/8″ in size around the periphery of the thermostat.
