Wow... it's hit or miss. The problem appears to be the corrosiveness of the coolant. Yes, it seems to be cool to have an all-aluminum "upgraded" radiator that has been pressure tested after manufacturing. (WTF? Pressurized with what? Water or air? Not 20,000+ miles of glycol ethanol/Toyota red mix.) When the coolant eats through the material, the radiator is worthless!
I'm tired of sub-par parts. If my intercooler hose had not blown off of my intake manifold and smashed into my shroud/upper tank... my original OEM Toyota composite radiator would be fine!!!!!!! And ready to last another 100K miles!!!!
