Why does Tacoma come with spring clamps on large hoses?

Speed of assembly !!

Is the real reason No doubt cost plays into it as well

I like the spring clamps I have no problems installing or taking them off.

In fact I have people that don`t like them give them to me.

Weak hands perhaps ??

 

I would not go as far to call people trolls, but would agree many people do not spend time scrutinizing the validity of knowledge they believe to be true. I would keep in mind there is a good chance your going to be wrong if you go against common practice. But I also like to scrutinize like you do.

I enjoy the questions you bring up. Especially when they challenge long held automobile tradition. Others should not be offended to answer these types questions. Instead they should enjoy the challenge to prove your premise/practice wrong without insulting you or your work hopefully.

After reading this I think I now understand the advantage the spring clamps have over the screw clamps. I was thinking at first the the clamps themselves were expanding/contracting due to temperature changes. And thought those screw type clamps would be better for this reason. But it's the inlet/outlet that the hose is connected to (and the hose itself) that is doing the expanding/contracting. The spring clamp allows flexing that the screw clamp would not.

I like. This seems like the right version of this type of clamp would have all the benefits of the of the screw clamp and spring clamp without any of the downsides.

 

Agreed.

 

but you see, perhaps due to the lower intellectual profile of most people who post here, unlike the higher profile of people who, for example, use Stack Exchange, what prevails here is religious-like adherence to tradition (toyota engineers, specs, etc etc) and any form of questioning/scrutiny is mostly viewed as distraction rather than legitimate quest for information and understanding how things work deep down at the fundamental level.

all of these machines, including the one i am typing this one, are made by man, which is an imperfect creature that (luckily) eclipses himself with newer, better innovations all the time. but those who do so do it because they are not content with the existing state of technology but seek innovation and improvement. in order to move forward, one needs to understand those fundamentals rather than just accept some holy word someone reveres as infallible.

 

While I am not opposed to running stainless steel on any automotive application, the type of steel itself, is not the knoght in shining armor everything thinks it is and is vulnerable to corrosion as well as rust. Just wanted to put that out there.

As far as my own personal opinion between the two I feel that either or is acceptable to use, depending on it's application, however!

I actually prefer the spring clamps over the T bolt clamps for the main hoses for sure. Much better distribution of pressure and you can tell.

 

As the temperature of the radiator changes up and down the plastic expands and contracts, similar to metal. The spring clamp allows for changes in this expansion, and lack thereof and adjusts accordingly, using nothing but it's own tension.

Old school part but it is tried and true and never have I once broken a radiator neck, end, whatever you want to call due to it.

As for the worm drive style, a large reason why I don't like them on the radiator. You set them to where you want them and walk away. These don't account for expansion and after so many expansion and contraction cycles you may find yourself retightening it due to leakage. As previously stated, you risk the possibility of cracking the radiator neck as well due to overtightening. This becomes progressively dangerous over time as you buckle down on the clamp. On smaller hoses and whatnot, sometimes yes they are useful as I said depending on application, where expansion isn't so pronounced. For the main assembly though, spring clamp all the way.

 

so now if i said that i am finally sold on the idea of using the spring vs. regular clamp after all this discussion, i wonder if the army of haters on this site would think this question was meaningful

 

the helpful contingent of the posters here is somewhere in the order of 10-20%, free estimate. the rest are just distractors. and yes, the ones that are helpful do exude earmarks of higher intelligence, i.e. they tend to explain why things work the way they do (vs dogmatic adherence to some automotive bibles), use proper english grammar, can structure their posts in digestible sections, are open to scrutiny and can defend their position, and so on.

 

I don't think it will matter what you use...I still stand by my earlier comment....back in July

 

One more thing. Worm drive clamps tend to bite into the rubber of the radiator hoses in all the open areas of the clamp where the drive usually engages. So not only are you potentially risking cracking your radiator neck plastics (this gets worse as the radiator ages). You are also not accounting for all the hot/ cold cycling the radiator goes through AND you are also cutting into the rubber of the actual hose which attaches. A triple negative threat for these clamps.

 

Goddamn you really do think you're a cut above everyone else because you asked why Toyota picked a certain clamp instead of trusting their engineers knew what they were doing?

 

Repeatedly questioning the [whatever] manual is why we're no longer living in caves and don't have high priests pointing fingers who's getting burned at the stake tonight.

So it's a good thing to question ANYTHING as long as you're open enough to accept an inconvenient answer provided validity

 

My guess is this dude probably lost some of the clamps and instead of shelling out for the proper ones he wanted to go to lowes and buy the first ones he saw.

But to save face he's "just asking a question instead of blindly blah following blah blah blah"

 

I just have to ask...Do you have Asperger's Syndrome?

 

Wait that's whys he's rebuilding the engine??? I must've missed that!

Stick to oil changes and air filters foam pile, the streets will be safer that way

 

For years I distained spring clamps because I found them futzy to work with and not particularly attractive in the bay of various muscle and sports cars, so whenever working with one I promptly replaced it with a SS screw clamp. Oriented neatly and with an easily accessible head.

I will say dear old Dad taught me how to properly torque them (by feel) to avoid most issues (hose cuts, collapsed pipes) that over zealous twisting gets you.

On my last street driven solo II car, on the advise of some more seasoned folk who had rebuilt/refreshed many a version of our little high RPM buggers, I decided to reuse the OE spring clamps, or replace them with new if corrosion called for it (it didn't). Their reason was the same as several posted here; guaranteed correct tension, no chance of fitting collapse, no chance of hose buggering.

For two specific clamps I would have bought a proper tool, just because of access issues, if I had not had several of the ancillary pieces out of the way for other reasons. As it was, 6" needle nose worked fine. And a basic set of hose pliers worked great for the rest of them.

I never had any issues with anything the clamps were used on, even running 7,200 RPM on 95* days (about as max pressure/flow I was ever gonna get to)

So for me, the upshot is application. I have no problem using either type. Just depends on what I'm working on.

Right now I have a screw type on my tailgate hinge. I don't expect to need to worry about the underhood hoses for 10 years or so. By then I may not care enough to fret over it.

 

Well I'll be back shortly, I have some reading to do

 

So true ...
