    On a 1998 S70, when you replace the thermostat, I see there is a rubber
    gasket that fits around the thermostat itself, but is that it?

    Is there another gasket for the housing...(don't see one).

    Do you just brush off the corrosion and replace the aluminum housing....or
    do you use some blue rtv?

    THANKS

    That's it just very gently clean the surfaces

    Glenn, (or anyone)

    I drained the cooling system really well on my 98 S70....(bad radiator, alot
    of "chocolate shake" in there).

    It's really running clear now.

    I disconnected the bottom radiator hose and fed the water through the
    thermostat opening for a few hours just letting it run on the driveway.

    Like I say ALOT of gunk passed through.

    So, now I'm going to replace all the (4) hoses and eventually replace the
    radiator. The overflow tank looks brand new from cleaning.

    I didn't open the engine drain cock when I flushed but from what I've read
    it doesn't make much difference?
    You don't get much out of there?

    Is that true?....will I be ok?

    Thanks !

    Also ran plenty of water through the main fill inlet which connects to the
    overflow tank.
