Silicon hoses (coolant) opinions are ?

[Basho]

The silicone hoses would have to be braided to stop the ballooning. My experience with silicone hoses are fuel lines for running alcohol as it eats rubber. The silicone is very soft and cuts very easily, Once it has a small nick in it you can tear it apart with very little force. I vote it's purely for aesthetics

Thanks mate , I have never used it for a liquid before but have used 5 layer for air (turbo induction) and found tearing or leaking was not an issue just the odd ballooning and even that was not consistant which is puzzling , I did however use the widest clamps I could find to avoid pinching.

The only silicone joiner in my car is for the intake, and it's purely because nowhere had a suitable rubber joiner.
Worst thing is it's hideous bright blue.

One end is slipped over the AFM, and held with a screw champ thing.
The other end is slid into the rubber base of the air filter and the rubber in clamped onto the silicone. (I put a hard sleeve inside teh silicone joiner to make it rigid, otherwise the filter would have nothing to clamp to)

yes, it's me bringing another old post back from the dead

I'm about to buy a full radiator hose kit for my NA8. I have previously used silicon upper and lower radiator hoses on a NA6 and found that they tended to leak, so I replaced them with OEM rubber ones.

Before I place my order is anyone one aware of a better deal on a hose kit?. I did look at getting it from mx5parts in the UK, but they only appear to be selling silicon hoses.

Maybe not, check the kevlar sets ... http://www.mx5parts.co.uk/advanced_sear ... ar&x=8&y=9

Silicone is supposed to last longer, but I don't know if we'll have the car long enough to find out haha.

For NA a set of genuine hoses is $130 from eBay USA.

Thanks Magna. I should have mentioned that I had seen the Kevlar sets.

As per the hidden link in my previous post, I'm looking at getting a set from Meccamiata on Ebay from the states. I've had less issues with the OEM hoses I've used in the past.

I had the kevlar radiator hoses from the UK, they developed small cracks after about 3 years and split about a year later.
I've gone silicon this time round so we'll see how long they last, I also took the opportunity to delete the metal pipe that joins the 2 bottom hoses together and got an NB bottom hose.

I've always used the traditional non-kevlar reinforced rubber hoses. No issues. They're still in very good condition, so they're going back on the resto. I sandblasted them for cleaning, as I sandblasted everything on the car. :-D Rubber loves it.

So, I ended up ordering a full set of original Mazda coolant hoses from Miatamecca

One week door to door from Arizona to Melbourne is pretty good. Paid around Aud$190 landed.
