Re: When did the DEX-COOLRrequirement Begin
In OEM application for the B-bodies (and I think D-body LT1 application) that valve (thank you Joe for using the proper terminology) is part of one of the heater hose assemblies. It is available separately as Joe points out. Some of the big car guys replace it with copper fittings from the local hardware or big-box store for an eternal solution, however I am uncertain of the engineering effectiveness of that solution. Others simply eliminate it and the attendant failures. All of these solutions, while functionally more or less effective will do nothing for gaining points in judging.
