Rumor has it that the cold tstats overwork your water pump. Not sure if this is a negligible point, but it's what I've heard

unless you require the additional lower temps for say a boosted motor, big compression motor or a bottle drunk of a motor then a stock 198* is plenty especially for a daily driver. You dont gain power with a stat. Timing with or without is the same.

not mentioned in winter months your heat isnt as hot as it would be with a 198* stat

Is it true about the tstat keeping the water pump under load for longer periods of time, though?

[George C]

water pump is always under load if anything it frees up the restriction sooner then later. figure with a earlier opening temp the water pump is flowing sooner then later, so if anything the stock stat puts more load on the pump

Ah I gotcha, makes perfect sense. I guess in theory then , a 160 stat would probably help keep the pump cooler too, which would have to be better for it
