For all the threads about failed radiators (and finding the best replacement), I'm wondering how many original radiators are still functioning just fine.
I'm about to hit 190,000 miles on my '07 LX, which I keep up pretty well (all fluids changed regularly etc.). Radiator is original and looks perfect. I just did a coolant drain/fill and the drained coolant looked like the new coolant (Toyota SLL) that I put in: clean, clear, and unstained. I've never flushed the cooling system with water, radiator cleaner, or anything other than straight coolant.
I also keep the radiator fins clean (by rinsing or using foaming coil cleaner), which I have long suspected makes a big difference in the operating temps of the radiator, and hence its longevity. The "Brown Death" that we take as an immediate precursor to radiator failure looks to me like plastic that's gotten too hot, and many photos of failed radiators show substantially clogged fin area.
Just spitballin' but I suspect that there are a lot of original radiators out there. "Plastic radiator" doesn't have to mean "unreliable" or "short-lived," IMO.
Curious to hear others' thoughts.
