N231-15-540B Coolant hose NLA

Post by Victorsanders »

Hey all.. in the process of refurbishing the engine bay..

I’m replacing all the hoses and have managed to find replacements for all hoses apart from N231-15-540B

If anyone has any spare ones or any leads , please do let me know.

Many thanks

Vic

Yea all sorted so far!.. hopefully it all turns up.. It was around £300 for all the hoses .. more than I wanted to spend. But I wanted to avoid universal hoses! Hopefully these last another 40 years 😂

Just a reference for anyone looking at replacing the various hoses

Took me a little while to find stock of them so here’s a guide for a finding replacements

9954-10-1601 - O-Rings used for beehive oil cooler. 4 required. Mazda only had 1 but Mazdatrix had a full set available for $7.40 per O-ring.. Viton can be used apparently but I’d rather use Mazda parts if they’re still obtainable.

N231-15-511 - Lower radiator hose. Mazda had in stock for £23.96 (only 4 available in Europe)

N231-15-521C - Upper radiator hose not available from Mazda. I ended up ordering a set of upper and lower hoses from Essex Rotary as they weren’t sold individually. This was £73.55 inc postage

8871-61-212 - available from Mazda for £17.40 (only 2 available in Europe)

FA42-61-213A - only available as back order from Mazda with no ETA for £18.32 or available from Mazdatrix for $14.84

N231-15-550 - Available from Mazda for £58.94 (only 2 available in Europe)

N231-15-530A - only available as back order from Mazda with no ETA for £20.89 or available from Mazdatrix for $26.54

N231-15-540B - not available from Mazda and I only got lucky finding a NOS replacement from Australia for £68.51 from Phil’s. Iv not been able to find a replacement from anywhere else

I backordered the hoses that could be back ordered from Mazda. But I may never see the orders fulfilled.

Might be a case that universal hoses are the only way forward .. or seeing if these can be obtained from Japan or the US from the dealer
