Thanks for letting me know , iv noticed before that sometimes the coolant is below the minimum, and never got any notification so i assume that this bypass was preventing that ?
still don’t under stand how a sensor located completely separated from coolant tank can tell the coolant levels 🤷♂️
It’s always worrying when you find bypass on sensors on a used car as you never know if it was a quick fix or there to hide something.
is this a common bypass ?
