Yeah, leave the 'flush' in there a lot longer than it says. And drive it. The heat makes the chemical reaction work better. Driving helps circulate it.
What year is your truck? Dexcool is great for aluminum-based engines. I wouldn't bother in my OBS though. The green stuff is a lot cheaper, get the extended range. I go to our local small-town chevy dealer and they will sell DexCool to me cheap out of their barrel (bring my own jug) for like 1/2 of what Walmart sells it for. They'll sell any oils cheap to me out of their barrels. The chrysler does that too. They have a mini-mountain of clean 1-gal milk jugs in the shop corner that people bring into the dealership ...lol. It's kind of funny. At the time they would sell me a gal of ATF +4 (which used to be super-expensive) for like 1/3 the price of walmart. Best if you walk in the side-door with your greasy clothes ..and jugs in hand. Dexcool is made by shell. Walmart sells it too. It's not as expensive as it used to be. If you already have dexcool vehicles, that it's probably better to standardize on the same coolant. If your other vehicles use green coolant I'd stick to that.
When you fill up your truck, use Distilled Water. Not tap water. It's like $1/gal at Aldi's or just about anywhere. If you use tap water you're just adding more mineral to your cooling system. The mineral comes out and attaches to areas where it'll be cooler (your radiator and heater core). So, for a couple bucks, it's the cheapest insurance you can buy.
