You can buy radiator flushes. I'm sure these will help with the heater core. Just poor it into the radiator. Run the truck for a while to get it circulating. Then after a while drain the radiator and then flush the heater core. You can also try a higher pressure hose. If you used just a garden hose. Step it up and go to a low pressure car wash. If you dare go higher. It does have a chance to blow inside the truck, but its your choice if you choose to. I did it, it cleared it up perfectly and did not blow mine. Also do it both ways, and do it 10-20 times.
