Whilst searching for coolant hose kits I have come across this set. Has anyone had experience with hoses from this source please?
Quality can be a difficult thing to assess just looking a images. But when you look at the price from other potential suppliers advertising in various places this set via AliExpress is soo much cheaper. Comments please. Whilst this source might be a total disaster waiting to happen it might also be the same source used by companies advertising here in the UK.
Silicone Coolant Hose Kits For MG TF / F PRT 1.8L 18N4S1 2008 Model - AliExpress 34
Hi I was led to understand that silicone hose coolant pipes can be affected by OAT antifreeze coolant.
Might be worth checking this out. Glyn. (I just noticed its for a 2008 model so is it ok for earlier ones?)
That indeed is a suggestion based on information from one U.K. retailer. They state that a specific compound in the particular OAT is detrimental to Silicone rubber hoses.
In all probability we will never know what is included in antifreeze unless a specific question is asked of the supplier who will in turn need to ask the blender/producer.
At present it is my understanding based on a very recent phone call to x-part that the stuff I have from them on my shelf contains the undesirable compound.
But I believe Comma produce a product that is compatible. I have lodged an email request with them for confirmation. I fully expect that a phone call follow up will be required.
I would need to check to be sure but I think their ok product is G30.
Clearly if they are making more than one OAT a it is for a reason.
There will be other suppliers producing acceptable OAT products the challenge is finding the right information.
Suppliers tend to take the view that you have a standard car and that if you select a product from their list for your car it will be ok. That does not mean it is ok if you change the MOC eg to silicone hoses. It is all part of “change control”.
I am unable to comment on the fitting arrangement. I do not have detailed knowledge of upgrades changes etc in hose fitting configurations. As far as I am aware there was "pre PRT" and "post PRT". More than that I cant comment.
Similarly I can't comment on the materials of construction variation between models i.e. who built what where and when in the factory. Rover/China etc.
The previous response was around the use of silicone hoses and compatibility with various types of Antifreeze.
From my perspective I will seek out an antifreeze from a supplier such as Comma in future (there are others obviously) and I have no financial or technical association with Comma or any other for that matter.
There appears to be more than one type of OAT (OAT, HOAT etc) and I'm not about to get involved in that discussion on here. I am not a materials expert.
Have a look at Comma or Valvoline websites to be totally confused!
Eg Comma G30, G40, G48 in various options such as extreme etc. You need the data sheets to see what is what.
Alternatively stick with standard hoses and plug in your VRN to the search features on various manufacturers websites.
If there is a risk of them potentially being dissolved by an ingredient in bog standard OAT anti freeze + there is also uncertainty of this being a full and complete set then thats 2 convincing reasons why i for one will avoid like the plague.
It would seem that I have not described the issue properly.
One or more products in a specific formulation of Antifreeze seems to contain a particular compound that is considered as a plasticiser. I’m told that the specific compound is not present in many antifreeze/corrosion inhibitors including OAT, and that there are many producers of those products that are safe to use with silicone hoses.
As stated I’m awaiting a response from one supplier/producer to confirm that the suggested product is acceptable/safe to use (I’m as sure as I can be that it is).
What I need to know is if anyone has purchased hoses from the Chinese source identified (AliExpress) and if so with what success.
Can anyone help with that please?
