My 76 Auto with A/C is running warm

I was hoping to stop my car from overheating. I tried  to put in a 3 core  radiator that I just bought and realized that it doesn’t have an oil cooler for the transmission. I also noticed that the air conditioner had a condenser bolted to the front of the radiator. Is there another more modern way to do this or should I just take out the air conditioner.  I was hoping to get that air conditioner running one day, but it doesn’t work now and I don’t really need it too much sinceim in Los Angeles by the beach.  The condenser seems to be restricting the airflow into the radiator, which I could probably just replace with a new original one and it would help.

thanks for your advice

Get your original radiator recored, not cheap, but a stock radiator with a functioning water pump and t-stat should run just fine.  If you redo your a/c buy a parallel flow condenser, just measure how much room you have, these are around $125, then get a SPAL or equivalent fun with Curved blades and a rotary compressor

I have found that replacing the old (Behr) condenser with a modern parallel one will restrict airflow to the radiator (even using a brand new Walloth Nesch high flow 3 row version).  My tii ran hotter than before I converted everything on the AC system. My car even has a 71 deg C thermostat.  I’m using a 12” Spal fan for the condenser AND the stock fan.   Was way too hot deleting the stock engine driven fan.

If the AC condenser is an original style one, throw it out. Even if you restored the AC system, you would use modern style components in the front nose of the car. The block might have alot of build up in it. Maybe run a radiator flush through the system and bleed and drain it a couple times. Also i agree with just having your original radiator recored. Should cost about $300.

    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
