Hi All, I have a 1940 Chevy truck that has a small block Chevy that was always running way too hot. I think it was mostly due to the way the small block sat lower and so the mechanical fan was only covering about 30% of the original 6cyl radiator’s surface, and also because there was no fan shroud. So last year I ordered an aluminum radiator and electric fan, but the width of the radiator was about two inches two short, so I cut two 3” wide strips and drilled holes to made brackets to run down the sides of the radiator to extend the mounting holes. The brackets aren’t welded, just held together with bolts. Also, and at the time it sounded good in my head, but I used thick soft rubber bushings with the bolts to kind of make the radiator a floating mount, thinking it would be less stress on the radiator and less prone to cracking if I mounted it this way. Anyway, the truck now runs much cooler and never overheats, but now going down the road, the whole truck kinda feels a little wobbly. It’s not a tire or wheel shimmy and you don’t feel it in the steering wheel, it’s like just the whole truck seems to shake while at speed. So I’m wondering if the radiator needs to be bolted directly and firmly because maybe it serves as part of the overall structure rigidity that keep the whole front end together? The more I think about it, I’m wondering if the radiator is an integral part of the whole front end. Now I’m thinking of removing the radiator and having the aluminum strips welded on and then bolting the radiator directly with no rubber bushings. Thoughts? Thanks!
