Yanmar water take-off fittings

[aitchem]

Hi,
Putting in a calorifier and I am unsure as to the threads on the fittings for the engine water take-off points. The engine is a 2YM15.
I am 120 miles from the nearest chandler, so it isn't practical to do a comparison first.
Sould the fittings be stainless.?
NPT parallel - tapered or something else.?

thx
Howard

Mine are standard chandlery, brass, straight, presumably BSP? Photo of them on my website under engine>calorifier in the indirect cooling part near the bottom of the page.

The threads in the engine are metric "M16" - hard to find in the plumbing shop, probably easier to get from Yanmar dealer

Thanks Vyv,

I always worry about pipe fittings because most of the time they all fit each other, but, have different thread angles ( I think ) its a worry.

I'll see if Yanmar reply to my question, (not holding my breath )

Would you mind updating this when you find out? I have a 2YM15 and am considering adding a calorifier. Thanks!

Isn't that why god created PTFE tape?

Can you look at my picture Vic.?

I have rolled-up paper in, what I think, are the in-out connections.
The horizontal top one goes to the thermostat housing/top hose, the rearward vertical one goes in the water pump outlet.

thx

Your engine is not identical to my 3GM but that looks OK to me.

Hope you will come back with the info and photo when the job is done, so I can add them to the website.

Thanks

What a ripoff

The Thermostat housing has a metric thread which requires a banjo fitting at a
Yanmar price of £86, including bolt banjo and copper washer.!

The Waterpump housing is an easier 3/8" NPTF ( Yanmar info )

I'll be getting something made by brazing 2 brass bits together.
