Delcotron Brace Chafes Corvette Radiator Hose

Chafing can occur between the engine water outlet hose (radiator inlet) and the Delcotron brace on 1963 air conditioned Corvettes.  Vehicles should be checked for this condition and if interference is detected the contacting area of the Delcotron brace should be heavily wrapped with plastic type electrical tape. Corvettes without air conditioning have the Delcotron mounted on the right side of the engine, and are not subject to this problem.
