Are you looking for the heater core or the valve? What year? There are larger valves and smaller valves? 

I’ll simply add you need to match the heater valve size to the heater core size.  IIRC, the change to the larger size occurred in 1971.

Ideally working unless I can be pointed toward a rebuild kit, but they seem hard to find.

Rebuilding my box the PO yanked out and it does not have the core.

Willing to a pay a fair price, but trying not to spend a fortune on a new one. Thanks

 

I think I have a late model valve I can sell.  PM me.

Is this just so the valve ID matches the heater core ID for ease of plumbing or is there another reason they need to match?

ID and OD need to match.  Outlet stub on back of cylinder head and return pipe alongside of engine block also need to match valve and core, BUT you can mix and match them if required.

 

My 69 has early valve and core.  72 engine now has smaller outlet stub and reducer fitting for return pipe.

My fault. I'm looking for the valve specifically for a 1973. The core measures 18mm OD so pretty confident its orginal to the car. And from what I understand that is the larger valve.

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
