I was thinking about how long the stock radiators lasted verse an aftermarket replacement. Could you tell us how old and milage on the original radiator when replaced and what brand was the replacement if known.

If you bought the truck used and don't know the answer to the above question but have had to replace the radiator, please tell us the milage, how long you think the old one lasted, and replacement brand.

Thank you,

I am still running the same OEM original radiator that was installed on the Dodge Ram production line but I flushed out the orignal coolant 20 years ago and replace it with Shell Extended Life Coolant (ELC). The new replacement radiators suck. Very crappy quality.

I replaced my OEM radiator in March of 2019 at 309,000 miles on the odometer. A small leak developed on the driver side where the upper part of the side tank connected to the core. I replaced the radiator with a Napa radiator - not sure of the brand, but the part number was 2464.

Truck odometer is currently at 403,000 miles.

I'll be heading into my 3rd Radiator now. I'm at 500k miles, and the tank gasket on the driver side is leaking. I cut the radiator cap vent disk off, and now the radiator does not hold any pressure, but I've been this way for over 1 year,r even with a 200℉ thermostat, and still have a leaking radiator still. This winter, I'm hoping to be able to replace that radiator.
