I replaced my radiator last month and it has a coolant sensor just like this. The outlet in the new rad was too big and caused a leak. My bush fix was to wrap the sealing surface of the sensor with Teflon tape. Maybe the coolant will eat at it, maybe not. I really had no other choice except getting another rad. All good for now though.
Coolant sensor leak
Hello, this weekend I was replacing the valve cover gasket and noticed the sensor in the water outlet was sleeping out coolant. I replaced the sensor today with a new one and it is still leaking. It seems there isn't enough downward pressure on the sensor to keep it from leaking. Is this a common thing I just have to live with or should I go ahead and buy a new water outlet? Thanks.
