180 or 190 thermostat?

i'd say if you're in texas or sit in stop n go all the time then 180 is better

if you are up north and just do free wheelin' 190 is fine


the real debate is whether your block passages are all clogged up and your radiator is all clogged up . those are way more important than thermostat performance lol.

p.s. never run straight water you will have rusty sludge all through the block passages and when it freezes outside your freeze plugs will pop out, and/or you will crack the block

overheating will also mess your engine up; after a real good overheat you will start hearing knock knock noises
