My overheating, radiator solution

Post by Vanquished on Sun Jul 16, 2017 4:03 pm

Thought I'd share the solution I used for my 350 overheating issue. My van was running at 230 degrees in the matter of a few minutes. Pretty extreme heat issue. I recently replaced the water pump with a Milodon high flow pump. Replaced the radiator with an aluminum one from Howe, part number 342A2816NF. I also used an aluminum Howe surge tank, part number 3424. I am using a 180 thermostat, with dual electric fans, pushing and pulling. My van is now running at a steady 190 degrees, in 90 degree weather. Hope this can help anyone still searching for a cure. I'll try to post some pics.

I've been thinking about getting that same radiator for my 68. How did you mount the bottom of the radiator? Do you have any pics of that?

I like your surge tank. Where did you get that?

I'm using stock style bottom mounts, with the rubbber insert that it sits in. Top mount is just sheet metal bent around top with flat rubber under it. The surge tank is a Howe tank, I ordered through JEGS.
