Installing Water Temperature Sensor

[Gary in NJ]

I have a new temp-sensor to install. I have the housing, threaded retainer and, of course, the water temp sensor. I even have a new cap and thermostat (might as well replace 'em while I have it apart) and all new gaskets.

I know to use pipe tape on the retainer, but do I need any sealant between the retainer and the sensor?

I've never used pipe tape nor sealant on them.

Pipe tape can tend to insulate the sensor from grounding properly, causing gauge inaccuracy.

That makes sense. I'll install it dry.

i put a dab of antiseize on the threads, but not too heavy for grounding reasons.
