Hi Everyone!

         Replacing the water pump on my 02 and noticed that a bypass cap was used to block off one of the outlets. What was used was a 3/4" cap which is in bad shape, so I would like to use a proper fit 1" cap. Local autozone does not carry a 1". Any suggestions where to get one or other options? Thank you guys, you always have the answers. -T.J.

So you do not have heater box circulation?

If you have a heater box, just as easy to get the bypass tube and hook it up proper.

I don't see where crosson9 has stated whether he has sidedrafts or a downdraft carb.  If a downdraft, then he has no manifold heating now.  If not then plumb it up as supposed to be.

A radiator shop is a good place to take a leak.


I have no idea what I'm doing but I know I'm really good at it.

I've used 2 approaches with that- either use a short piece of hose and an internal plug that fits inside the hose,

or run the rubber line forward, then splice into the heater line that goes to the back of the head.  I put a small

restrictor in there, as it's a 'heat leak' but I found that it helped with bleeding the air out of the head.


I've never seen those caps for cooling systems, and using household plumbing on cooling systems would make me a bit nervous.

TobyB, what would be an internal cap? links or pics to give a clear idea. Thanks you all for your input on this!


Also, hose clamps. Some better than others or are they all the same?


Piece of rubber hose and a bolt of your choice that fits...

    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
