Water Divider


Recommended Posts

My water divider keeps leaking at the hoses. I replaced the hoses and clamps and it still leaks. After looking over the water divider, it is pitted and might be pitted all the way through the metal.


1) The water divider shares its gasket with the intake manifold?

2) Does the intake manifold need to be removed to remove the water divider?

3) If so, can the intake manifold just be loosened enough to slip new gaskets on the studs or realistically will the intake manifold need to be fully removed?



This is a '76 2 barrel with no emissions equipment.

1) yes, the divider shares a gasket with the #1 intake port

2) you can remove the divider without removing the manifold

3) However, if the gasket is damaged when removing the divider, you need to pull the entire intake manifold off the studs to clean up the old gasket and install the new one. At that point, good chance the other three intake gaskets will be damaged, so plan on replacing all four.


Pitted water dividers are fairly common, though I've never had one so bad that it leaks. An option would be to dry it out and apply JB weld to fill in the pitted area. After it dries, reattached the hose and see if it still leaks. If not, you are good to go. If it does--new divider and four gaskets. BTW, the water divider can be difficult to get off of the long stud, try to clean out as much corrosion as you can and then use some penetrant on it.

Thanks for posting this, I just got a good divider from the FAQ marketplace, as far as how badly they can corrode, mine isn't just pitted about 1/3 or half of the extrusion to mount the hose on is gone, I had to push it up as far as I could on the divider to get it to seal.  Anyway, now I know why I was having trouble finding the gasket for the thing, should have been looking for a manifold gasket.

    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
