73' 2002 overheating when idle


Recommended Posts

I have a 73' 2002 automatic with no modifications. Lately, I have been driving and noticed that when the car is idle, like in traffic, or at a stop light, it begins to overheat. The temp goes up quickly considering I'm at a stop light for less that 2 min. When I begin to drive, it quickly cools down again.

Any suggestions of what it might be? Stuff I should look for?

Thanks,

JW

Hi,

the most likely culprit is that the radiator

is restricted on the inside. but, you should

also check that the front of the radiator

is not plugged with dirt or leaves.

curtis ingram on this board has the only

good radiator replacements. you may need

to send him yours because most automatic

radiators have a cooler in them.

good luck

Actually, that really DOES sound like the fan-

if the car cools itself while it's moving, then the rad's working.

One other idea- a sticky thermostat that isn't opening the

little bit it takes to increase water flow when you stop...

Thanks, I just checked the radiator and it was like 3" below the fill line, WTF! Especially since I have been to the mechanic regularly for the last four months (odds and ends). I did check the fan belt and it feels a little loose, I have about 1-2" of pull on the belt.

I'm thinking of flushing the radiator out, but do you think that might be overkill? I was going to wait to see if the correct amount of fluid helps out with the heating issue.

If not, then I'm going to tighten the belt. Thanks for your help and I will keep you posted.

Um, tighten the belt anyway-

if you're cooling at speed, it's not slipping,

but it could. Or it could decide to part company with the

car, which would be... bad.

Low coolant will do it- I cracked a head that way...

    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
