I have a '68 340 GTS finishing restoration and a couple of the oem style corbin hose clamps are leaking. Has anybody else had this problem? Should I go to a different style?
My Honda S 2000 has the wide style Corbin and they work great, so I think I'm going to look in that direction.There are a couple of different styles of corbin clamps. Which do you want? The old wire style slap SUCK dead elephant balls and will sometimes cut into the hose. The wide style is much better. I don't care if I had a concourse restoration, if I ever drove it, I would want the wide style. They are much more dependable.
I have always had leaks on every car I have ever had. EXCEPT my dart once I put the correct wire Corbin clamps on.There are a couple of different styles of corbin clamps. Which do you want? The old wire style slap SUCK dead elephant balls and will sometimes cut into the hose
I've got to talk to the guy whose working on it as the engine is a 71 340 and the pump and nipples are different than 68. He changed one of them as well. I may go with the newer wider corbin style like my Honda S2000 has, as they work well and look better than the worm screw clamps.Professor..
You beat me to it.
In a nut shell, the clamp kits sold by Dales Cuda Shop, resold by Classic ind are sized for perhaps NOS hoses.
Some of the clamps do not fit readily available hoses of today.
Example... The radiator of small blocks have the same size tube for in and outlet. The thermostat and water pump are the same as radiator. Yet the kit supplies two different sizes for heater hoses. Two work, two leak like a sive.
I contacted Dales and he told me it was my reman cast iron water pump.
I have some of the bypass hose clamps extra still pm me and I can get you a couple.
I'll look into he Gates clamps. I'm finding that the wide corbins are mostly offered in smaller sizes probably as the engines/hoses are smaller.I think the biggest thing that makes these type clamps fail is that over time, seepage causes corrosion and rust between the hoses and "whatever" they're attached to. From there, that's when the leaks start. I like the above idea of the contact cement, but even then, the contact area needs to be CLEAN. I would even endorse a light coating of RTV.
I'll have to measure. I think the clamp called for is 2 1/8 to 2 1/4. Would your clamp make it?The corbin style band clamps on my Dakota could be used on 2" Radiator hoses.
