My coolant sensors are working ok, but given they're 20 years old and corroded I thought it might be time to consider replacing them. Having never bought replacement coolant sensors before - where would I buy them?
Some say that if things are working ok leave them alone- normal maintenance of course required. A 20 yo car will have many items which are worn. The photo suggest that there has been leakage but the internals of the housing look fine. A clean up and hose and clamp replacement will probably be successful. How old are the hoses/ clamps- 20yrs?
Hoses/clamps etc aren't an issue, I replaced the lot with the coolant reroute. I cleaned it up a few weeks ago. Sensor still works ok so I'm leaving it.
