Good To Know

Q: Do I need to drain the cooling system before replacing this sensor? A: Yes, draining some coolant is necessary because the sensor sits directly in the engine block or thermostat housing. Having the new sensor ready to screw in immediately can minimize coolant loss during swap-out.

Q: How does a bad coolant sensor affect engine starting? A: A failed sensor can send a false cold signal, causing the engine computer to inject too much fuel and flood the engine. Alternatively, a false hot signal can make cold starts highly difficult.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
