Hmmm. I had my OEM rad recored last summer. Wasn't cheap so I was hoping I could leave it for a bit.
And of course new water pump, shroud in place, and new fan clutch.
Good to know about the gauge.
The 79 series is a bit taller so how's that obvious benefit, but its also built using different materials and internal structure which may also work towards improving its efficiency. I had my original re-cored as well with no noticeable affect, not until I switched to the new radiator.
