Was just about to refit the used thermostat into my rebuilt engine I ve tested it in boiling water an it doesn't seem to open or do anything
Some I m gonna buy a new one is there a specific brand that lasts longer than others
Does anyone have a link
Sure the only ones I have seen are originals, try Fowlers or wemoto, maybe Yambits?
Yambits! Expensive but gets the work done
