Why does Tacoma come with spring clamps on large hoses?

I understand spring clamps are convenient on smaller hoses. But why does Tacoma use them on large (radiator) hoses that can easily accommodate standard tape clamps that are regulated with a bolt ?

I found that the bigger a spring clamp is (and the more force it takes to hold it open), the easier it is to bend it out of shape and the less convenient it is to use it (takes more strength to hold open). So I plan to get rid of them on the radiator hoses and use standard.

 

Speed of assembly is my guess. I still have these type clamps on my 97 GMC. Work great with the correct tool and they don't get mangled. I'll have to check my yak as I never noticed. lol

 

i just use either slip joint pliers or channel locks, depending on accessibility

 

that is simply not true

 

i am saying that your B.S. attempt at explanation is based on an incorrect assumption. you can ask a question (not know the answer) and still call out a possible explanation BS if it doesn't ring true.

 

you have no knowing what my work is like as you've never seen it because you're just an internet troll

 

Dude asked a simple question and you had to get all snarky and smart ass on him. High five.

 

there are lots of assholes like that who use this site to heal their personal frustrations

 

Do you have an explanation or source? I'm honestly curious.

It does seem counter intuitive. Wouldn't a screw clamp tighten around the hose the same as a spring clamp. Sure the inward force "squeezing" the hose would not be perfectly distributed surrounding the hose. But it's hard to imagine a spring clamp would be meaningfully better in this regard. If I'm wrong, I'd like the understand why. In terms of creating a seal, the screw clamp would seem superior. The screw camp has potential for greater force than of a spring clamp and able to deal with higher pressure. I understand that automobiles use spring clamps for radiator hoses, but it seems reasonable to ask why.

 

I don't have a scientific test to disprove the validity of this but I have a gut feeling it is 100% an unfounded rumor and I will find it, just give me some time.

Anecdotally, the screw tightens a uniform strap that wraps around the hose so the pressure that originates at one point (screw) is distributed across the whole strap -- this is not an explanation that cuts the scientific rigor methodically but i'm sure the finding will be something along similar lines.

 

Lol. I'm in for the impending fuckery.

 

I'm gonna put my money on.......MONEY. My guess is, spring clams are a few bux per million clamps cheaper and that is why they're used. Sometimes the engineers win, more often, the bean counters win....

 

same thing can happen with spring clamps if the rigid male the hose goes over mangles under too much pressure of the clamp, which unlike a strap clamp cannot be regulated

 

i was thinking something along those lines

 

Because a spring clamp is easy to use, easy to make, has a predetermined amount of pressure and eliminates the possibility of something being over torqued.

I couldn't begin to tell you how many radiators I've had to replace because of backyard/uneducated mechanics over tightening a hose clamp too tight, cracking the radiator neck.

Toyota uses what they use because it works, and has so for many, many, many years.

 

Because that's how the Toyota engineers designed the engine.

 

Couldn't had said this better myself.

 

Definietly has to do with the fact they provide even pressure.

Same reason oetiker clamps are used over screw type clamps in alot of situations.

 

Lots of fun, interesting banter on the subject. But really, what it boils down to is what engineering has determined to be best, given the parameters in which it will be subjected to, and by what is readily available, at the right price. That's science and the bottom line interaction. Popular right now are the spring clamps because of the limited or set compression strength, more often used in automotive applications because of its worry free installation. From experience, aerospace and non commercial marine use defer to screw type clamps, or smart screw clamps that incorporate sleeves, and torque the screws to the engineered specifications.

My primary concern for any clamp used, would be the material it is made from, and how it holds up to repetetive use ( compressions and decompressions). Most wire type spring clamps are made from spring steel, and if not properly treated, will tend to corrode. Most screw clamps are just plated steel, also capable of corrosion. One should choose carefully dependent on the application, and always utilize where possible, non corrosive metal like stainless steel.

But really, as a consumer, it's all up to what you want. Cheap shit or the good stuff. You decide.

 

Spring clamps also provide even clamping force during temperature variations and resulting expansions and contractions, while a standard gear clamp will not, and the result can be leaks at cold temperatures. Constant torque gear clamps will give continuous clamping force, but at a much higher cost and more difficult and time consuming installation time on the assembly line.

Removed and installed correctly, spring clamps can be reused many times, using the proper tools and anything but ham-fisted techniques.
