I wanna E21 coolant branch

[ray_]

For to stick another temp sensor!

 

Thanks!

... but, but, but don't you need the coolant nipple to heat the intake manifold?

 

the e21 dividers are used for dual carb conversions due to the lack of that nipple.

 

(borrowed photo from jrhone's old for sale ad)

 

My '76's divider has an extra boss that could be drilled for a second sensor.  Maybe you could find one like that and drill/tap it?

Hmmm. I stand corrected!

 

My fitting has no boss there.

 

Maybe I can drill a hole in the intake coolant passage!

 

?

['76mintgrün'02]

well, there is (what I believe is) a temp switch on the underside of my intake's coolant passage... could you use that location?  (assuming your intake has one too)

 

see it hiding under there?

Well I don't have that port. I do have this plug...

['76mintgrün'02]

Hmmm.  I wonder how much cooler that location would be, compared to the divider; since the manifold's heating jacket is doing battle with the cooling effect of the carb.

Various switches are of course available. But those threads on mine aren't the typical switch size anyhoo...

Maybe you could change the title of your ad to 1976 water divider wanted ?

(although I don't know whether they were all like mine)

 

Or, I do have an e21 divider and I could weld a nipple onto the side of it (and put it in a box with that air cleaner).  

 

I used these little calipers to measure the nipple on mine and could drill out this 5/8" rod, or make a slightly longer one by turning down the chunk of 1" stock in the photo; which would also allow for a ridge at the end.

 

I forget which type of fuel pump you have, but if it is the stubby style, I could angle the nipple down a little, to help with hose/pump clearance.

 

We should probably switch to emailing now ...

I believe this is the divider that you need: PN 11531256642

^indeed!

 

Though that one is way too pretty!

 

Maybe someone can 3D print it for me!

Would this work for you?

Thanks Bib, but I think it will not. I need the small hose port for the intake coolant line opposite the two large ports.

 

Thanks for the effort!

 

Cheers,

New e21 part from BLUNT is on my 69.  Cosmoline was difficult to remove.

This is the part you need:  https://www.ecstuning.com/b-genuine-bmw-parts/flange/11531261528/  and it is only 70 bucks.

 

The e21 efi version that Jim has is now NLA I believe.  Looks like BMW is replacing it with the e30 version, 11531274009

 

Here's the e21 and e30 versions.

I think you had better change the title of this WTB ad Ray.

 

Perhaps, WTB '76 water divider (?)

If they were all like mine, you could just drill and tap that extra boss.

 

EDIT: now I see the one in Hal's link.  Perfecto!

(and from your favorite supplier!)
