Mark Price, you said... >Isn't the control valve under the dash on a classic? ...which would then make this under-hood valve unnecessary, no? I assume you mean the water valve that is controlled by the temperature control lever on the instrument panel. If that's it, then I clearly would not have had one on the line under the hood. Excellent. Cheers, Gwen Smith ______^_____^______ (O|O) =RAMBLER= (O|O) Gwen Smith * gwen@xxxxxxxxxxxxx ------------------- www.gwensmith.com/interests/rambler \-<>---|770|---<>-/
