thermostat drilling safety bypass holes

With this thermostat mod the engine runs a bit cooler.
01.2024 EDIT: apparently its no good during the winter, as the engine has troubles warming up. I think one hole at most should be enough.

Max two, good job. People always overdue it then complain; 3 here, 3 here & maybe just 1 more to be safe 🤯 "folks, if it has a jiggle-pin that's considered a hole"
