hey Guys and Gals. Last year I installed dual electric fans on the 81 Malibu. I found out the adjustable fan switch didn't adjust, they where ether on or off. So I bought new switch Hayden #3653). Now they come on and off when I want them to. Setting in the shop the fans cool the Bu all day, But driving up and down the road 50 to 60 MPH the gauge is telling me the fans are on. so I just order a new Champion radiator from (koolradiatorscoolingsystems). That should do the trick . Three years a go I bought a Champion radiator for the El Camino and love it .
