The UAC website says that the CO20145C is an acceptable replacement and is an HT6, although they do not list the Delphi6628 under its cross-references. But UA...

Re: Dye on 17 year old Delphi 6628

Login problems with my initial account. Gave up and created a new one.

17 years and 200k miles, not bad, but given the current low value of the truck, I'd like to give it a try. Where can I find details of the repair procedure?
