Silicone Hoses

[davyboy]

Hey all, I'm having a bit of trouble finding hose kits or anything for the b5. I want to do all air and water lines in blue silicone (doing engine bay blue and silver).

Anyone know anywhere that still has or makes kits for this car that ship to Canada for less than an arm and leg lol?

I know ebay has full silicone kits, for like 80 bucks.

Should have specified not for intercooler, getting a full fmic so all the rest, coolant, vac, and pcv lines. The ones I've had the most difficulty finding is the radiator lines

www.votionspeed.com maybe

Make your own out of aluminum pipes and couplers. Looks nice.

Had thought about this but with the number of bends in the lines and flex locations I'm assuming there would be tons of couplers, unless I simplified the system up and got silicone tubing for smaller flex lines it could turn out well and look good, you wouldn't happen to know about how much of each diameter of aluminum pipe?

No, I've been lazy and haven't done this on my car even though I want to.

Well I guess if I can't find a write up I'll have to make my own though I have simplified the vacuum system so I may have less hoses than most people.

You'd think it'd be easier to find 3.5mm silicon vacuum hose. Shocking that ECS doesn't have a warehouse full of the stuff. I'm probably going to order some from here: http://www.siliconehose.com/0-1375-3...e-vacuum-hose/

[davyboy]

I've done the small stuff, wanna do the rest. All that is left under my hood that's 3.5 mm is the im to fpr and im to dv lol

radiator lines have to be custom as they have the quick connectors.

[MarcRogers]

034 sells Coolant hoses for the rad. Upper and lower. You have to cut the plastic on the OEM connector since it's like that slide and clip thing. There's a PDF on it. I'll find it. But I'm sure if u find the size you can deffinetly get it way cheaper on eBay.

Can someone tell me please if these lines can be used for my DV / fpr lines?

Yes for your FPR lines. They just aren't good for brake lines. Why you gonna use SS lines for DV? Just use silicone.

[b5a4erik]

SS wouldn't be better?

I thought they'd look cooler too, but if they aren't good performance wise then I'll reconsider.

For the pressure/vacuum the only benefit on fpr and dv you'd get with stainless is the appearance and even then it's not much, my fpr has maybe 6" line and the dv you only see 6" or less of it so you'd be spending all the money on the appearance of something you barely see. My .02 just do silicone for those two, I did when I removed that stupid computer controlled valve that controls the vacuum to the dv.

I figured I'd need to order the proper spec for the larger rad hoses with that quick connect plastic piece (that I'd have to reuse) but for the one that connects from the overflow tank to the hard line, that has several bends, would I be able to safely just use an adequate length of silicone tubing? Same for the rest of the lines that just use standard hose clamps?

P.S. Would running silicone couplers with aluminum tubing be acceptable in the various systems of this motor?

[Spectre1130]

Yes, for vacuum lines just use silicone tubing. I like the stuff from siliconeintakes because its thick walled (doesn't collapse under high vacuum or expand under high pressure) and being silicone it doesn't dry rot.

SS is nice when you have corrosive chemicals (due to a teflon core) or high pressure fluid systems.

but for the one that connects from the overflow tank to the hard line, that has several bends, would I be able to safely just use an adequate length of silicone tubing? Same for the rest of the lines that just use standard hose clamps?

I use silicone hoses for my overflow tank and for my turbo lines. Works just fine and silicone is generally more resistant to the heat. Just make sure they are the correct length. Too long and they can kink, too short and they might pull off.

P.S. Would running silicone couplers with aluminum tubing be acceptable in the various systems of this motor?

Yes, I would assume so as long as you connect them all correctly. I plan on replacing my coolant hard pipe with aluminum piping and couplers. Only caution with replacing the hard pipe is making the seal for the coolant temp sensor housing. If you have access to a TIG you can get the aluminum housing and weld a different flange to it though.
