Anti Freeze leaking....


Goudey

Recommended Posts

Have not run my 76 2002 since June. Just noticed a puddle of antifreeze under the engine ( not the radiator) and the #3 header pipe is wet with it as it seems to be coming from the stud or flange area of the #3 header.

Would this be a likely head gasket problem or just leaking exhaust flange gasket?

Have had a slow rise in temp after running engine for more than 30 minutes at 50mph.....changed thermostat, checked all hoses and radiator and coolant quantity stays up....checked timing etc. Could not account for the rise in temp almost but never into the red....

Any help is appreciated.

You answered your own question. If you are leaking coolant, that probably accounts for your temperature rise. Sight unseen, the headgasket is my first guess. Exhaust flange gasket has nothing to do with coolant containment nor am I am that stud contains coolant or even contacts it. There is the possibility your coolant passages are terribly corroded to the point where area around stud is leaking. That would be very unusual and you indicated using Antifreeze which deters such things.

    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
