Silicone hose for 850, V70, S70, C70. 94-2001 Group Buy

Post by **tryingbe** » 18 Mar 2014, 13:35

I asked Mathew and he's ok of this thread being here.

I have access to a supplier that can make silicone radiator and overflow tank hoses for (type1) Turbo 94-97 850, (type 1) Turbo 98 S70, V70, C70, and (type 2) Turbo 99-01 S70, V70, C70. If you look into the silicone hose, you'd know every few people make overflow tank hoses. These hoses are for turbo cars only. Hose is 3 ply, may require you to use bigger hose clamp because of the thickness of the hose.

Type 1 replaces

94-97 Turbo 850 sedan and wagon.
98 Turbo C70, V70, S70
Expansion Tank Hose
9135267
Expansion Tank Hose
6842894
Upper radiator hose
1335433
Lower radiator hose
3507930, 9470409

Type 2 replaces

99-2001 C70, S70, and V70.
Expansion Tank Hose
9445378
Expansion Tank Hose
9470676
Upper radiator hose
1335433
Lower radiator hose
3507930, 9470409

I have a type 1 kit on my Turbo 850. I had to shorten the hose from thermostat to expansion tank, all the other hoses fit great.

Currently looking at $120 shipped for each kit. Turn around time is about 2 months. Looking to start at the end of March. Please send PM if interested.

Color choices are black, blue, red, and purple. Each set will come with 4 hoses, depends on the type you want.

Does it have a non silicone liner? Silicone hose passes water vapor much easier than quality EPDM hose.
Start watching this video at the 5 minute mark for info.

I just don't see a need for these when OEM hoses last a ridiculously long time. My original radiator hoses look and feel new still. The only hose that really degrades is the coolant elbow underneath our turbos, mainly because they get soaked with oil, soften, and burst. Replace it and you're usually good for another 150k...

I had NO IDEA that the NA cars had a different coolant reservoir overflow hose to thermostat housing than the turbo models???

I went to iPd's website and they claim they share the same part #.

Thanks JDS60R for sharing the Gates video on water permeation thru silicone.... fascinating! Thanks!!

There are four hoses in the kit. Three are the same between NA and turbo, one (the lower radiator hose) is different.

Wow, I had no idea silicone hoses suffered that problem. I wonder if IPD is aware of this.

the gates video is interesting, but that they have a product to sell. i think the point about permeation is not too big a deal for us.

they state that a truck driving two shifts year-round will lose five gallons through an EPDM hose, but for a volvo driving maybe an hour or two a day you're not looking at the thing leaking like a sieve. the loss for silicone may be an order of magnitude greater than for EPDM, but that's an order of magnitude more than negligible. might be an issue, might not. i'd guess not.

the bigger problem, i think, would be the other thing mentioned in the video: silicone doesn't tend to "stick" to fittings after you clamp down on it. if a silicone isn't evenly clamped to a fitting, it's much more likely to leak than the equivalent elastomer hose. the video claims this can happen in cold weather when stainless clamps don't shrink as much as aluminum fittings, and having installed silicone hoses with worm drive clamps in the past, i believe it.

that said, if i had seen this post two months ago i'd be busting out the visa. $120 for everything in that picture ain't bad.

Under this buy, you won't get everything in that picture.

Guys, OP did not make it crystal clear but this info is there if you look carefully:

FCP isn't. In a burst of irony, they provided a new blog posting about the benefits of silicon hoses. In the comments section, someone provided a newer Gates link with the same type of information about the benefits of EPDM that we got from JDS60R.
