    Go to any auto store & buy a worm drive clamp.

    Also I doubt the issue is the champ, more likely the hose or even the pipe rusting.

    Suit yourself but for what it's worth my I've had regular worm drive clamps on my bypass lines for nearly 10 years and they don't leak.

    T-bolt style clamps are good in some applications but they need a lot of purchase area and are very bulky. Remember your cooling system won't ever see more than 14.7psi pressure....

    I'd seen it squirt water jets... I'd even added additional worm drive clamps as well as the spring loaded ones and it still leaked. Was a pain to get on too.

    lost about 2 litres of coolant in about 6 months... so it had to go somewhere.

    i may be biased though as I've ruined countless worm drive clamps. all cheap crap of course... but thats all I can find for sale

    Ive used Tridon worm drive clamps that you can buy at supercheap on those hoses.

    Touch wood no issues.

    tassuperkart Its a lie I tell you!

    If your stripping out even cheap worm drive (Jubilee) clamps, then crushing the hoses with bloody great T-bolt clamps wont achieve anything more than eventually cutting the hose off and maybe looking for the REASON for the leak might be first and foremost.

    If the hoses and the necks are new, they wont leak even without a clamp there then id be suggesting the hose is slightly too big for those necks.

    Those water necks are actually a funky size and when I replaced those pesky thin-walled rubber stock pipes with some brutal multi-layer silicone pipe used for truck engines, the hose sizes were either slightly too small or a bit big.
    I almost busted a poofer valve fitting on the slight tighter hose but the bigger version was too loose and clamping it up would be a bitch.

    Those original spring clamps arent designed to stop leaking, they are there to stop the hose from popping off. I try and use them almost exclusively and I collect as many as i can.

    You need to look at the installation closely rather than just clamp its brains out with a zillion pounds of clamping force which is just a bandaid and likely temporary solution.

    E

    Those spring type clamps are as weak as piss but, they work PERFECTLY to keep the hose in place.

    Last time I had this problem, I actually looked around for high quality worm drive clamps (and I hadn't stripped those ones out on this hose in particular, but generally speaking, I have split many, from large sizes like for the pod filter, but a million small ones for things like vacuum lines, fuel lines and coolant lines on motorbikes).

    Worm drive clamps came in handly last time as I was able to open them up and thread them around the pipe to double clamp it just enough to stop the leak... however this time it was the ones at the back that were leaking... and there was no hope threading on new clamps without pulling it all apart.

    Another issue I have with worm drive clamps is that it rips into the hose... even with these new high quality ones on new silicone hose on new hose barbs and just enough pressure to stop the leak... it still gouged through. These T-Bolt clamps don't have that the holes, is nice and smooth, and has a nice long radius built in under the bolt... though limits size range.

    These new hoses I got were from unique auto and are specific to the zed for this problem.

    I've wire wheeled the cast pipes, cleaned everything up nice and this time I've applied goop to the barb and hose...

    So I say the hose: "Leak one more time mo**fu**... leak one more time. I dare ya. I double dare ya!"

    Also fyi I'm not stupid enough to clamp it so tight that it crushes the tube or splits the hose... lol.

    Hopefully this will be the last I hear of it.
