Just curious as to the difference in the types. I am looking for some hose to use on my coolant lines. But I dont see any differences in them is it all the same or is there special type of hose you use for collant system applications. _________________ 95 GMC Yukon 6.5 TD 2 Door Tow pig/ Daily driver.

On my SS connection, the blue hose Terry Kay supplied, has to be the best hose I have worked with. from my engine block, i used reinforced high pressure marine hose. and for the heater hoses just the good year rubber hose. kock wood, no leaks.... |

I've kind of shied away from silicone hose due to its tendancy to leak when cold. I'd heard this but used some anyhow and it would seep overnight. Something about it not having as strong a "memory" to grip a given nipple when compared to quality rubber hose. Rubber also seems to stick on after a while and you have to break it loose, where silicone comes right off just like the day you put it on with no apparent sticking. So, you have to use a special "constant tension" clamp with it. I got some of those and still got the odd drip over the year I used it.
At the end of the day, between the hose cost and the pricey clamps it was quite expensive and did not seem to ever seal well. So I dropped its use.
Somewhere I have a package of sweet clamps, and even another thing I was going to try to stop the leak - clamps you heat shrink into place.

Good read. There is another post here where a van owner was losing coolant and couldn't find a leak anywhere. Something to research and consider a little more. The lifetime warranty on the silicone is what makes them attractive to me. _________________ 1986 Root Beer Syncro Tin Top....so many plans.

This has been brought up before. Watch the video in the other thread. It shows that silicone hoses permeate water at "10 or more times" that of a rubber hose, but not coolant since the ethylene Glycol molecules are larger than water molecules.

Yes. This was the thread I was thinking of, and that is right - he was losing water not coolant.
Did you end up running silicone or rubber? _________________ 1986 Root Beer Syncro Tin Top....so many plans.

Where do you find new rubber hoses for your I4 conversion(same for diesel, correct?). _________________ 1986 Root Beer Syncro Tin Top....so many plans.

I have using silicone hoses on various vehicles including Vanagons for over 10 years without issue.
Not all hoses are created equally.
The GeeBee hoses I have had in service for over 2 years have been awesome. |

Everything that I did at the rear was custom. The only stock VW hoses left in the system are the two at the front coming from/going to the radiator.

Yeah, I'm not knocking the silicone hoses at all. It just seems that some amount of care needs to be taken to ensure that the hoses stay tight on the fittings/tubes and monitor any water permeation. I chose rubber because it was much cheaper and much more convenient given the custom nature of what I was doing. _________________ "Sometimes you have to build a box to think outside of." - Bruce (not Springsteen)

I have been contemplating upgrading to silicone and this writeup has helped me make the decision to stick with rubber. I do enough weeping over the van, I don't need silicone hoses that weep as well. For some reason I though silicone would "last longer" but hell my 30 year old hoses are still fine. There is obviously more to this than my small brain can contemplate.

A rubber vs silicone hose debate should produce as much of a stalemate as the stainless vs aluminum pipe debate.
Go with what you resonate with. |
