Failed Radiator on 2002 GMC Sonoma

Anyone heard of a radiator in a GMC Sonoma going bad after 50,000 miles?

yes all the time the coolant(dex cool) is hard on radiators and makes them leak at seams
Can I put a different antifreeze in the radiator beside the orange stuff?
yes but the system has to flushed completely b4 you use a diff coolant. if not it will cause major damage to mix coolants. i rec you stay with dex but change every 30 to 40k miles
I bought the truck with 30,000 miles and in 3 years put 20,000 more miles on but never changed the coolant. There was no indication that I could see that it need to be changed and the places I took to have work done never said the anti freeze was bad.
well maybe you need a new mech.
