I have a 1973 BMW 2002 and live in an area where summer temperatures average 100-105°. The weak cooling system finally made itself sufficiently known to the point where I couldn't use the air conditioner. Continual complaining by my wife caused me to get the thing fixed.

I called several radiator shops for estimates to install a thicker, heavy-duty core (old one 1.25", new one 2"). Total cost ranged from $74 to $109.

In June we had a record temperature of 115° (quite unbearable) and the car performed like a champ. The needle now rides right in the center of the gauge regardless of outside temperature.
