Those 3126's are definitely not early models. I've heard that suggestion one before from the Cat dealer in that area. It sound more like a way to run your survey cost up to $12,000. We did an informal poll in 3126 owners on CSR and did not find one owner who had an after cooler failure needed to replace one.
Suggest you ask others here what their experience had been. We went from 12 pairs of 3126's in our marina down to 4-5 pair now as people aged out of boating or traded up. I never saw an aftercooler replaced….but cleaning the seawater side is easy in this marina. They have a portable descaling machine that recirculates descaler continously so taking care of the cooling system is painless and fairly inexpensive.
