Not realy i dont think



Comming from top down

Straight 32mm to 100mm alloy connector to 90 bend to alloy 50mm alloy connector with either a peice of flexi 32mm

not sure if the prt is 32mm yet may have to get a reducer

at the meet today though someone did mention that the OAT antifreeze is no good with silicone as it will eat the sillicone

but my question how quickly

im going to call a few places and maybe even a call to ASH to find out how they stand up to OAT

and if it does i think my solution will e swapping to evans waterless stuff

i also heard this but it made me think if it would eat away at it so bad why would companys make silicon hose kits for the k series?

[Jay160]

well my idea is to make it as bullet proof as possible

once the whole lot has been done and alloy manifold ect

i think it would make sense to use the waterless stuff anyway .. pricey but no pressure

i think will only get a good answer from the guys that make it

Hmm, that's a bit worrying.

Surely though most modern cars use OAT and silicone cooling hose kits are available for most cars. If there was a serious problem with OAT and silicone then loads of people would have had problems but I've not heard of any?

[Jay160]

yes ive read on a few places mick last night saying the same

but they say the same question .. the arguement is is how long? and there doesnt seam to be an answer

well spose its best to do a test

ill fill two jars with 50/50 mix and some need oat and put some of the off cuts in them so can keep an eye on them ;

ill even bring some up to a high temp to .. only thing i can think of

and ill phone ASH later

[Jay160]

had a nice chat with the guy at ASH this morning and basicly yes over time it have an effect on there pipes

but even he says they dont know how long or by how much

He did say that if you use oat they will not cover the hoses .. pretty much gathered that

But there are going to phone the makers to see if they have done any tests to see how bad it does to the hoses

Discussing our cars he said going the waterless route would be the best option

so with the price you save on there hoses and the exspensive replacement hoses oem ..
i carnt see being out of pocket

I've just got a little update regarding the OAT and silicone issue.

Firstly, this is the antifreeze that i used;

http://www.commaoil.com/productsguide/view/6/352

Its OAT but has added silicates.

I emailed Comma regarding the issue of OAT and silicone hoses.

Here is the email i sent;

Hi,



I have recently changed some of my coolant hoses for silicone hose and cleaned out my cooling system and re-filled with xstream G40. Since then i have read that OAT coolant can react with and eat away silicone. Can you tell me if that is the case with the G40 too? Any information you could provide on the subject would be most helpful and gratefully recieved.



Many Thanks,

and here is the reply i reieved;

Good Afternoon,

Thank you for your enquiry.

This is not something that we have come across so I am happy to say that there is no such issue.

If you require any further information, please do not hesitate to contact me.

Kindest Regards

So according to Comma they dont know of any issues regarding this antifreeze and the use of silicone hoses. Whether or not this is the case only time will tell i suppose.
