Street Rodder magazine has a section in the back "for those that drive em" this is more "for those that give a sh!t". If that is not you, turn the page and read the advertisements. GM restorers all know that the well detailed engine bay includes the usage of GM Tower Hose Clamps. Mechanics however all know the reproductions are cheap and will likely fail if not the first time you install them, soon after you remove and re-install one a time or two. This isn't a restoration site and this isn't a restoration tale - it is a tip for those of you who, like me, appreciate a retro engine bay with back in the day finishing touches. Backstory: A buddy and I took a 69 Camaro Pace Car across the block at BJ a few years ago that had a fresh engine build and she (the car, not my buddy) "burped" leaving the block, popping off the upper radiator hose that was secured with tower clamps resulting in the engine bay being showered with warm antifreeze exactly 30 seconds after the someone else paid well over a hundred grand for the car. A few seconds earlier and I would have been the one who soiled myself at the cost of a lot of money and equal amounts of embarrassment. That day I had an idea to build a clamp that appeared to be a tower clamp but with the safety and surety of a worm gear clamp. Fast forward to today. The '62 Nova that I am building (on a separate thread) to sell at the swap meet in Portland next weekend, leaked a bit of antifreeze after a short run through my subdivision last night. The culprits once again were the tower clamps that do not tighten far enough to hold the small diameter radiator hose on the top of the 6 cylinder engine. It harkened memories of BJ and I knew I had to fix it properly. My choices were slim, worm gear clamps were the only option...but that didn't mean they had to look out of place. Here is the fix I put on it this morning before work. Start to finish, one hour with nothing more than a screw driver (the tool, not the drink), needle nose pliers, band saw or cut off wheel and a vice (again... not talking about drinking). I had a few extra heater hose tower clamps to experiment on, the tower is the same on all of these clamps as is the width of the clamp band. So I stuck one in the vice. Using a flat blade screw driver I pried up the 4 flanges that secure and hold the tower clamp together, then I cut the clamp with a band saw to free the part I wanted. Only one cut is needed. This is what I was after; the tower, screw, cage nut and the arched, flanged based plate. This isn't rocket science but it is creative (probably why NASA didn't do panel paint jobs on the Apollo rockets in the 60's). Take your worm gear clamp, the parts above and reverse the procedure. Bend the tabs back down with a pair of needle nose pliers. Note: this "tower clamp" section is floating on the radiator clamp so you can position it later at installation where you want it (prior to tightening the worm gear clamp) so don't spend a lot of time trying to make it perfect right now. And a shot of the business end of the clamp. Finally, the clamp installed. Barely visible at the bottom is the worm gear and the extra band after I trimmed off a bit of the extra material with a pair of metal shears. Also note that I installed the clamp with the worm gear inward toward the fan so it is hidden, giving the appearance of a GM tower clamp. I tightened the now inoperable tower clamp bolt to a level that looks like it is doing it's job holding the hose and added a bit of thread locker to make sure it doesn't back off and get lost. I'd like to be there when someone tries to remove them using the tower bolt! Like I said, it ain't rocket science and it isn't a "tech week", life changing, "why didn't I think of that" kind of thing but if you dabble with GM cars, appreciate a vintage engine bay, like the look of tower clamps but fear the possibility of their failure or you have an application where the tower clamps just don't fit your application like in the case of my Nova, then here's how to fix your issues and hold your water. HAMB on! Bandit Billy 10-10 on the side!
