Read the bottle of coolant. It IS important that you use a coolant that is approved by the manufacturer of your vehicle. Contrary to popular belief, coolant is NOT coolant.
Yep, I knew exactly what Coolant to buy just not the application. I found my Truck manual book after posting this earlier today which answered the question for me. Dexcool is specifically made for GM vehicles. Im all good now and the truck is happy. Just need to add my Fuel cleaner the next time I fill up and she will purr nicely. 2002 with 65k is not bad; I bought it with 11k so ive put approx 13500 miles on per year. Just keeping up with the maintance.
