Double Pass Aluminum Radiator

By: David 09/17/2019

Well Summer hit and all the cooling modifications I did helped a tremendous amount BUT still couldn't keep it under 230deg on the freeway/highway in 100deg temps outside with the AC on. It could barely do it if I stayed in the slow lane with the AC off. So I bit the bullet and went to Ron Davis Racing Products here in town and he suggested a Double Pass Radiator with Two Rows of 1" wide Tubes, I said sounds good and in about a month I had a brand new custom built Aluminum Radiator. I had them also design the brackets to attach my Electric Fan. My design would have probably been duct tape and zip ties, JK, actually maybe not kidding.

I bought a nice new shiny fan pulley because, well, it's shiny. And you can see it now with no fan attached to it :-)

Due to the Double Pass design the top radiator hose inlet was on the opposite side and I couldn't really find one to fit so I made my own (which I didn't know you could do but now I do) out of two 6" 90deg silicone hoses and two connectors and two hose shrinky dink thingies.

This Radiator did the trick! I was able to floor-it down the freeway with AC on and the temp never got above 200deg! And just going with the flow of traffic it rests around 195deg. BUT.... (to be continued)
