As stated, if it's a 38 year old radiator it would be best to replace if it shows the slightest blockage or leakage. A new radiator makes a BIG improvement in cooling.

Interesting…
Is it possible to have a 38 year old original radiator, well cared for, leak free, sludge free etc, that has still lost efficiency?
From what I’m gathering, these things experience internal corrosion no matter what.
