Do you guys use an overflow resevoir?

KFunk--I assume you've relocated your battery? Or did you go below the battery tray?

Nah, battery is still there.  It's literally behind the headlight.  There's a gap there.  I can't remember if I drilled a hole for the bracket to hold it, or if there was already a hole there.

The Autozone one can also double as a fuel tank for your motorcycle to power through an escape tunnel out of a mexican prison:

. I can't stand the thought of leaking coolant on the drive because its poisonous to animals.

 

don't want to spew extra coolant down the highway while going through the mountains or at high speed on a track,
 

 

excellent motives for adding a catch bottle!  coolant under a tire is slippery.  i did the same thing kfunk did.   plastic bottle right behind the headlight.

I have one of these behind my driver's side headlight (just got my second after a deer hit the first). They should have it in stock at every autozone, even if you make the guy search the back room twice, he'll find it somewhere:

http://www.autozone.com/heating-and-cooling/coolant-return-kit/interdynamics-1-5-qt-coolant-return-kit-for-compact-and-smaller-vehicles/360489_0_0/

It's cheap looking, but its set up for the job and works.

And yes, I run one for a lot of reasons. I'm sure the car can handle it, but my car isn't exactly stock, and all cooling system parts won't work forever. I abuse it heavily, and don't want to spew extra coolant down the highway while going through the mountains or at high speed on a track, just because I mis-measured how much of an airspace should be at the top of the radiator. Just fill it up all the way, and you'll have less chance of air bubbles, too.

Did you connect the runoff tube at the top or bottom?

The overflow tube from the radiator goes to the bottom of the reservoir.  The final overflow tube goes from the top of the reservoir to somewhere near the bottom of the car, however you want to run it.

 

At least that's how I did mine, and makes sense to me.

I installed one on my very first 2002, a "late" 71 with the 72 body trim and 1 barrel solex.  I had lots of overheating issues.  It had me stumped because the rad flowed just fine.  What I could not see was the build up on the inside of the tubes from previous owners using the wrong anti-freeze.

 

At any rate, I used an overflow bottle from a 70s Volvo.  Easy to fit, easy to install, and worked as it should. 

 

cheers,

Michael

Did you put the container horizontally in the space behind the headlight? That seems like it would fit better horizontally than vertically, if I remove the mounting tab first. Did you drill holes to mount? I don't want the container to bump around on the headlight wires.

I did mine vertically, but you can do it however you want. I put some little bolts and nuts to hold the bracket to the lip of the core support (?), and if there weren't holes there already, I drilled 'me.

LOL...at least yours is mounted with a bracket.  mine is stuffed in there loose!

 

Mine was in there like that too, until I used a crowbar to pry the front end and headlight outward to their proper pre-deer locations.  Then it wouldn't hold on its own anymore, hah.

Ha -- mine's just wedged in there too (bottle bottom slanted inward, not near any wiring). Doesn't seem to move around any either, even while hooning. ;-P

To be more effective, you should have a "sealed" radiator cap.  Back in the 80s I found one at the auto parts house made by CRS (coolant recovery system?).  It was plastic, yellowish in color, and had several rubber seals on it that fit in the neck of the radiator, allowing the coolant from the reservoir/bottle (like many above, wedged in the space by the headlight) to be drawn back into the radiator after the car was run.

    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
