I've often wondered the same thing. Everyone is like your fans will run all the time but HOW if your thermostat is opening at a lower temp?I'm a little confused with the post. First, the HHP instructions are for the 180 degree thermostat. Are there different recommendations for the 196 degree thermo? Also, why would a thermostat that opens at a cooler temp cause the cooling fan motors to run constantly if using stock programming (as stated in the HHP instructions)? I would think the opposite would be the case. If the engine is running cooler, the cooling fan motors with the stock programming would run less, not more, right? And what is the benefit of a cooler thermostat if the fan settings are set to come on at higher temps? That sounds like a zig-zag - the zig of the cooler thermostat is negated by the zag of cooling fans that don't come on until the engine is warmer. What am I missing?
