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.
