PHH supplies...

[Josh83]

I'm looking for 5/8" silicone hose to do my PHH and none of my local places have it(NAPA included). I found some stuff on McMaster but I'm not sure if it is right. I can be found here :http://www.mcmaster.com/ctlg/DisplC...55871874948&ScreenWidth=1024&McMMainWidth=812 . It is the stuff at the very bottom. It is listed as 5/8" ID 7/8" OD Silicone rubber. Is this what I want? Also, do I want the "soft" or the "firm"? I assume soft.

Uh, no. I doubt you want to use a hose with a max PSI of 6 at 72 degrees. C'mon man, you did the research, read the specs!

I found hose at a big rig parts supply place. Or, the link in Firetruck's post will take all the guesswork out for you.

Is there a Finning dealer nearby? They gave me a couple of feet, gratis.

I just ordered the kit above with overnight shipping. I don't have the time to chase this crap all over the state. I live in a pretty small town, so if it doesn't come from wal-mart or Napa you are driving 30+ miles one way to get it.

I think the kit is a good bet. I probably would have gone that route if I hadn't already done one of these and stocked up. Collecting the parts was a PITA.

The area NAPA warehouse had the silicone hose, but wanted $24/foot. I bought 6' of it from CarQuest accross the street at $9/foot. Nobody but NAPA had sleved hose clamps and they would only sell them by the box from the warehouse. I told them the size of the hose, they handed me a box of clamps... that were too small by 1/8". Back to the store, since I'd ruined one of the clamps trying to make it fit the hose, the partial box was non-returnable. So, I bought another box of the same clamps a size bigger.

The extra 5/8" silicone hose is handy to have around. It is overkill, but it works for the upper hoses as well.

The other alternative is Gates Green Stripe hose which you can get almost anywhere if you ask. It isn't silicone, but has some other advantages in actual use. I chose it over the silicone hose, and use it in all of my Cruisers.

have to pipe in and say that i spent a few hours trying to track down gates green stripe and it was very very difficult. live in dayton, oh and NOplace had it, including truck repair places... finally ended up using good quality gates heater hose w/ appropriate temp/psi rating.

What advantages?

 

[Cruiserdrew]

What advantages?

It is chemically resistant, heat tolerant, very thick and strong, and will adhere to metal pipes to decrease your chance of leaks. It really is excellent stuff and worth taking the time to find. Around here, Car Quest sells it, and Napa will get it for you if you ask.

I concur with Drew. The greenstripe is physically more durable, thus does not require lined clamps, and seals to the metal pipe better, and thus does not require, nor benefit, from constant torque clamps. It is not clear to me that the silicone hose offers any real advantage when used in a cruiser, and the increased likelihood of silicone hose leaking and is a disadvantage.

Just to set the record straight...

Look at these cross sections... the SFS silicone hos has 2 layers of tightly woven nylon embeded in the silicone... Green stripe has one not so tight. Silicone burst strength is a magnitude higher than Green Stripe with a higher temperature rating...

Green stripe is good hose though... way better than generic. Silicone is way better than Green stripe.

All normal worm gear clamps will losen with time... the OEM clamps that come on the PHH from Toyota are better than the worm gear clamps that will losen over time.

Top is SFS Silicone, Bottom left is Generic Silicone (Crap IMO), Green Stripe and Good Year High Mighler (good - VERY stiff though).

I will be getting off my A$$ and updating my website with all the specs of various hoses along with a stiffness rating that you should take into account when working the PHH onto the metal pipes in the very tight confines of the PHH location.

PHH supplies should come with Knock Sensor Epoxy.

 

[Grench]

Knock Sensor?

PHH supplies should come with Knock Sensor Epoxy.

I've done two of these PHHs and I haven't had any trouble with the knock sensor that I know of...

How would I know? Would it throw a CEL code if I did anything to it?

Thanks!

 

[Houston FZJ80]

Me don't understand.

 

[firetruck41]

It would be easy to break the connector on the knock sensor while doing the PHH, due to it's close location to the inlet, and its (apparent) fragility.

As far as I can see the strength and temperature tolerance of the Gates Greenstripe exceeds what is required in this application. That fact that it is physically more durable than silicone hose, and does not require special hose clamps, and is also much less likely to leak due to its natural ability to bond to the metail pipes, which the silicone hose lacks, all leads me to believe that the Gates Greenstripe is the better choice for use in this application.

Mine has lasted for 10 years/ 145,000 miles (factory one)
and still looks pretty good. I'm changing it with
the Gates Green Stripe version in the next few
weeks and I'm sure it'll last at least as long.

.......oh and thanks Houston FZJ80 for the quick service!!

Just ordered my hose from Houston, and look foreward to fighting the PHH next week.

Thanks to all who went before me! I did mine today- it took several hours (4), I think I could do it in half the time if I did it tomorrow. I used the Gates green stripe so hopefully wont have to worry about it for a long time. Mine is a 97 with 71000 miles- still looked okay when I cut it open.

I did get a slightly bruised forearm, but otherwise no worse for wear. It was impossible for me to get the new hose on until I took the bolts off of the transmission dipstick to get some extra wiggle room. Hopefully it won't start to leak after being "disturbed".
