OEM Radiator Hose Spring Clamps or Screw Clamps?

[ajs]

I'm planning to replace radiator hoses #1 and #2 (and generator drive belt, and tensioner pulley bearing, and potentially thermostat and gasket) because of a coolant leak.

I ordered OEM clamps as well. Looks like the PO replaced the OEM radiator clamps with stainless steel 028 032/57mm screw clamps (like these). OEM clamps are spring clamps.

Any thoughts on reusing existing screw clamps instead of switching to the OEM spring clamps? I'm pretty new at this, but the spring clamps "feel" like they might not work as well. Then again, the screw clamp is the one that is failing.

OEM clamps or (Breeze) Constant Tension style worm gear hose clamps FTW....they will maintain proper seal as coolant system hoses expand (heats) and contract (cools).

No sign of leakage or seeping at my hose ends ever even with my 14 year old original OEM clamps transferred onto new aftermarket (Gates) hoses a few year back....

Thanks much!

Yes sir. You can find OEM hose numbers here in this thread: https://forum.ih8mud.com/threads/coolant-hoses-the-complete-list.1100994/

All the hoses/clamps that you need can be bought with one stop shopping from @NLXTACY at Wits End. Joey can hook you up here!! 100 Series 2UZ Radiator Hose Set

I actually already have the OEM ones, via Norwalk Toyota. Was just matching up the to-be-installed parts against what's already there when I noticed the screw clamps.

Thanks for the recommendation re Wits' End. Will definitely check them out for my next order (and 15% off through 12/1).

Roger that...you can't go wrong with OEM on the parts that you plan on changing.

My belt tensioner bearing seized and shredded a new OEM manufacturer Mitsubioshi serpentine belt 15k miles after my last 90k service. When I inspected everything at the service interval all was quiet and smooth in the pulleys. My mistake not changing it at 215k!!!

I also run that red Toyota long life coolant 50/50% with distilled water in my 100s. No complaints here!!

I don't care about OEM clamps or not on the radiator hoses. But OEM hose clamps are really nice when replacing hard-to-get-to heater and bypass hoses, like the ones on the front of the engine. That is because they come ready to install, like on the factory assembly line. Put them where you want, pull the red metal cap that holds them open, and done. No hose clamp pliers or messing with a screwdriver in tight spaces.

I did mine a few months back and I was pretty set on using the screw style clamps, but after reading flippedbezel comment about the clamp style being able to deal with the heating and cooling better I sort of regret it.

Suppose you can't go wrong with OEM, it lasted you this long, might as well stick with it.

As said, spring clamps are the preference in hard to reach areas, but nothing wrong with the one P.O. used on your vehicle.

If possible, it's nice to keep everything drive train as stock as possible and the stock clamps are very affordable.
