V8 Expansion Tank / cooling problems

[Steve Kramer]

Okay, gentlemen.

My v8 has been overheating again.  I know that I need to replace the fan
clutch and radiator.  As said before the car is fine unless at long stop
lights. (Second fan also works when a/c is on)

  Previous owner said fan clutch was weak - but most likely a clogged
radiator would be the case. Those are projects I will be doing.  But my
immediate concern is my expansion tank is leaking.   I have ordered a new
one from Blaufergnugen (sp) and it will come with the bleeder hose and the
rear hoses attached tomorrow.

How do I remove the sending unit ( wire and connector)  in the base of it ?
The tank looks like it is attached by 3 screws. My guess would be to remove
the 3 screws, the sending unit connector and loosen up the hose leading to
the right rear cylinder.  But how do I get this connector coming up from the
bottom.


Also I may need to replace the thermostat.  My manual says it under the
right side intake manifold.  Do I remove the top plastic cover - and then is
it accessible ??  Don't know where it would be.


Thanks,
