As I said the set of five hoses I recently purchased from Avia Leisure do not have either the lush project no. or the Mazda Part no. stamped on them. The descripions of them are a bit different from those in the fact sheet. ie. Avia description "Top Engine Hose" which I think equates to "Thermostat to Head" on the fact sheet for instance.

Top hose usually means the big top hose exiting drivers side top of engine going forward & down to the metal pipe & on to the rad, the "stat to head" pipe on the factsheet (hadn't realised that'd been done) is the bypass/recirc from the head into the top of the stat, a short, smaller bore hose in a sort of c shape - 15 261 on the diagrams.

That factsheet only shows 2 of the schematics, which doesn't cover all the hoses/pipes if you check, you need all 5 schematics courtesy of lushprojects in the above linked thread to see them all, no point showing half the system IMO. The verbal bit is misleading on that factsheet, there are 17 hoses in all, they are all part of the heating/cooling system which is all interconnected & all just as important as each other. Don't particularly want my name associated with an incomplete factsheet, can't remember having input on it. Sorry to sound a grump, but it's going to confuse & mislead people if it isn't right.

Thanks Kirsty. It would have been be helpful if Avia Leisure used the Lush Project or Mazda Part numbers on their hoses rather than a verbal description to make it easier to work out what I have bought. Since Flippa's Silicone hose website no longer seems to function I also don't know the numbers of the nine from his first set that where fitted to my Bongo. I need the lot replaced for Ady to do the job for me and re-bleed the Bongo.

Looks like I am going to have to crawl under my Bongo when the weather improves.

Hi
My two-pennorth:
The silicon hoses seem to fail round about 18 months. I seem to remember other members having this problem at around this time period.
I bought a complete set of hoses, some of which I replaced whilst servicing about 18 months ago, and the rest this summer. Those
hoses mounted 18 months ago are failing one by one....WHILST STATIONARY!!!!!!! Currently, we're only about as cold as England, and haven't had the usual severe cold yet, and I would say that the hoses are just age-hardened after limited usage, as the ones I replaced this summer are still viable.
Anyone who has these silicon hoses should check the integrity. Mazda original, with decent clamps is the only solution
Cheers
