Jonny to the rescue...Thanks! It was the clip that secures the heater core valve cable under the hood cowling. I finally ground the tip off of a 1 1/2" screw and placed it under the tab with 45 degree tweezers. With one tap of the hammer onto a screw driver, the leaf clip was on....done. Only 2 days to figure that out. Welcome to SL world. Enjoy the ride. See ya at the dinner.
