I have read those. The OEM radiators had plastic side tanks, tended to crack. Or when you went to bleed the radiator the nipple would pull off with the hose. Makes Timeless' experience all the interesting.
It seems car manufacturers are going back to the way DMC equipped our cars, the last radiator change I assisted was on a 2014 BMW 550i with, you guessed it, cracked plastic sides. To boot, the water pump has a plastic impeller shaft. My 1988 325is still has its OEM all metal radiator, thanks very much.
