who run aftermarket upgraded cooling systems?

i'm honestly curious about the long term reliability of these more expensive but much better built aftermarket cooling system components

i'm thinking of the zionsville electric fan + aluminum expansion tank + super beefy radiator, combined with better watter pump and thermostat

do these really cut down on your cooling system maintenance and remove that worry completely?

I have a Zionsville cooling system. Going on 4 years now with no issues. It's not cheap at about $2500. But the peace of mind I get by having this system, knowing that at some time my fan could explode or the radiator will split or any of the other problems that come with an OEM system. The money was well spent. If you have the money and are gonna keep your car for a long time get one.

I bought the Zionsville radiator, a 16" flex-a-lite fan from Summit. I installed it in the shroud. Think the whole thing cost me about $750 which included a PWM speed controller.
