Great thread, guys!
Just to add to the discussion on worm-drive clamps/Jubiliee clips vs. spring-type/constant-pressure clamps, Pat Goss, the mechanic on the MotorWeek television program, says that worm-drive clamps should never be used to attach a hose to a plastic fitting, because over time the plastic fitting cracks under the pressure point caused by the worm screw, which leads to leaks and failure of the fitting: Cheers, Don |
Makes sense and agrees with what Bob wrote. Just hard to find.

What I learned...
1. Those constant-pressure screw-type hose clamps are elegant but fussy. They tend to come apart if you open them too wide and you can't see the connecting ring when you do. Nearly impossible to re-attach. Also, those large heads on them mean they don't work on the thermostat hose barb. They work fine on the radiator barbs.
2. The spring clamps from McMaster-Carr did work. I had to start them on the hose with a big channel lock pliers because the cable pliers I got did not have enough range to compress them. once on the hose, the cable hose clamp pliers worked wonderfully. 3. The hose barbs and the crossover pipe appear to be a maintenance item in that they had eroded on the forward ridge on the hose clamping surface which no doubt contributed to the hose coming off. 4. I should not try to be so clever with non-OEM solutions. 5. Before trying to put the hoses on the radiator barbs, boil a pot of water and let the end sit in it a few minutes. Makes the job much easier. 6. I am certainly no mechanic! :icon_nut: |
