Guest 1onesy Posted September 12, 2012 Share Posted September 12, 2012 No,that looks like it wood open a vent or something.This one opens and closes the heater control valve under the hood.It sits onthe intake manifold on the passenger side near the firewall Link to comment Share on other sites More sharing options...
Rivieraman Posted September 12, 2012 Share Posted September 12, 2012 So your talking about the water check valve? Those have not been avalible and hard. I have one it is a spare for my car Link to comment Share on other sites More sharing options...
RivNut Posted September 12, 2012 Share Posted September 12, 2012 It's probably not a Riviera specific item. Check any Buick, Cadillac, Oldsmobile, or Pontiac for a range of years and models that have the electronic temperature control module. In the years that I spent working on 6th generation Rivieras, I ran across one that was in good shape some years ago. I sold it a couple of years ago. Keep searching.Ed Link to comment Share on other sites More sharing options...
