    I cleaned my expansion tank after replacing the radiator and now have
    a defective coolant sensor.

    Apparently, these are sold seperately and installed on the expansion
    tank -- not as part of a new tank.

    So, I haven't looked closely yet, but how does the new sensor mount in
    the tank?

    Does it screw in with some sort of sealant? -- Push in?

    Is the old one easy or hard to get out?

    I assume you mean the collant level sensor?

    They are screwed (from memory) into the bottom of the expansion tank.

    Just pop it up from its mounting and peer underneath- you will easy see...

    Great -- thanks Tim.

    Yeah, the sensor. Any problem getting the old one out? Should I put
    some sealant on the new one, teflon tape or something?

    Appreciate your help.

    well, I had a leak in my coolant reservoir.

    replaced it w new one.

    there is a float around a tube going up in the reservoir. One reason
    the cost is kinda high.

    the sensor just snaps into the bottom.

    however, when I put everything together the coolant level sensor light
    comes on.

    called dealership, they said might need a new sensor.

    more money.

    now I just check the level which is good, and live w the coolant light
    being on.
