Anyone know a supplier of a good quality silicone replacement for the rubber outlet pipes. i.e. the ones that connect from the engine to the water pipes ?

 

I know I can get the rubber stock ones for $5 each but I'm wondering if there is a stronger alternative ?

Luke at the Z centre has some.

I got samco they are the best! ;)

Ah but do they do the heater ones as well????

Dan does superb Silicone pipes, proper stuff - 100% silicone!

 

Defineately worth asking him bud. HTH :)

Stu,

 

I have looked into providing these particular parts in silicone and have come to the conclusion that you are better off with the stock parts. Main reason being the high temperatures endured by the hoses as well as the properties of the coolant itself. You would need hoses that are at least 5-ply thick plus a fluoro liner to protect against temperature damage. I can get these but you'd be looking at a price of around £12~£15 per hose which IMHO is completely overkill and not good value for money.

They wouldn't get any hotter than normal coolant hose Danny!

That's what I thought as well but having run a pair of silicone hoses on my own car I can confidently state that the corrosion and heat damage to both the interior and the exterior of the hoses was significant enough for me to conclude that the silicone hoses weren't worth the money. They were good quality hoses but not 5-ply/fluoro lined hoses though.

 

For the money it makes more sense just to buy the OEM hoses.

The standard silicone hoses will take 180°C which is more than adequate for the application, I am running these on my engine without any problems.

 

Just to be correct-

The extra plies only increase burst pressure and not temperature rating, standard 3 ply at that bore size will take more pressure than an OEM hose which only tend to have 1 ply.

Fluoro liner is for oil protection and not temperature so wion't make any difference, if you want higher temp rating then you need nomex fabric plies instead of polyester.

 

These in silicone would only cost £5-6 each so are better and not expensive. If you buy a one of the well known makes and not cheap ones from ebay etc then they will be fine. Sorry to sound matter of fact but those who know what I do for a living can confirm I know what I'm taking about :D

Thanks for the comments / advice guys.

 

I wasn't too worried about engine bling with these as you won't really be able to see them. I was more interested in getting the best heavy duty ones for the job.

 

The reason I'm trying to iron out the small problems and prevent them happening agin in years to come is that when I sell the car next year, I will have peace of mind that the new owner won't have any problems that I could have prevented.

Fair enough Anthony - I know what you do for a living and will accept that your knowledge on this matter far exceeds mine.

 

However, my findings were based on "SFS" branded tubing which after 3 months use showed significant corrosion on both the inside and outside of the hoses. I then switched to a fluoro lined hose from a different brand and that has been fine for over a year. I'm not sure what happened there but I can't argue about what I've personally witnessed.

Dan, if the hose has been 'corroded' then returning it to the manufacturer might of been an idea so they could check and let you know what had happened. It could be a raw material issue or one with your car as normal coolant doesn't corrode silicon. I have seen the other brand hoses with the black liner but it isn't fluoro, they use a standard silicone liner as a 1st ply on their hoses. Having looked at the tech spec and they are similar ratings to the SFS brand. I know many people who have run these hoses (and samcos) on their car for years with no issues at all

If someone could sort some high quality replacements for these hoses it would be appreciated as these are common issue on the 300?

Consider it done! ;) Anthony - I need to speak with you ;)
