Is it the rubber in hoses or the clamps

Postby twocams » Sat Dec 12, 2015 1:44 pm



I used my first hose clamp around 1959 when I was 10 yrs. My dad was a back yard mechanic and we fixed his cars all the time. And I have been using these same type of spiral hose clamps for over 50 yrs. Only change is, some you get have a place for using a 1/4 socket to tighten them as well as using a screwdriver. I even used them in the USAF for 20 yrs. And on all my own cars (5).
Put new Napa hose and clamps on my 85 Aspy. Usually I tighten the clamps just enough that when pushed by thumb on the screw itself and dont move they are tight enough. But these damn hoses keep dripping just enough to pissmeoff. i have tightened each hose clamp at least 4 times each. They stop dripping....good. Two days later one will be dripping again, or if I start the bike up.
The one on the bottom of the radiator, which is the smoothest piping, drips the most....& gets tightened. May end up changing that hose altogether. As the radiator no longer lines up very well with the water pump outlet cause of the Alt. there. Rad. had to be moved out to accommodate the fan belt. So that hose could use a slight curve.
So im thinking it must be the cheap rubber being used in our hoses these days. I had the same problem on my 84 VW Rabbit...leaks,my 99 Dodge truck. I got them stopped by just keep after them, if it drips tighten it. Now am I the only one with this problem, say it isn't so. :shock:

I would make sure the pipe is good and clean and put some plumbers tape on the pipe and then slip the hose on and clamp her down good. But if you have old rubber pipes you will need to replace them good luck-----------------------------------------------Hal

If you switch to a nice heavy spring hose clamp instead of the screw clamps your problems should be over .. a screw clamp only exerts pressure of how much you tighten . then if the hose squashes a bit the clamp is loose and the bugger will leak ,, with a spring hose clamp there is always some pressure on the hose even if it squashes a bit there will still be pressure on the hose from the spring effect .. Also the lower rad hose on the 1200 is totally exposed to gravel and debris from the front tire beating it constantly , so if you insist on using screw clamps at least put the screw part out of sight so to speak so the **** cant hit it and beat it loose . I think originally the bikes came with a coil spring over the lower hose to help protect it ..
be careful when you tighten the clamps as the upper and lower rad tubes are very light and will collapse if the hose clamps are tighten to much . Honda as well as many japan manufactures originally used the wire screw clamps which I will never know why except maybe the obvious ( Money saving production ),, probably Have a good one

I have never liked spring clamps much. And didnt have any handy. So went with plan B, may have to go with plan C and get some. :( The coil spring is still being used on the lower Rad hose.
Thanks guys for your input.

I use the worm gear type hose clamps that you can get at any parts store,
and I always tighten them with a 1/4 inch drive ratchet not a screw driver,
you can`t get them tight enough with the screw driver. buy two of them, tighten one
till it strips, the second one just a little less than that and you will be good, being a
mechanic for a living I already know when they are about to strip, always just short of
that.
