Check your thermostat, you may need a new one. A good stock one will work fine. BTW the temp ratings are STO (start to open) temps. Make sure you get one the right length or it can bypass too much coolant and make the engine overheat. One other thing you might check that might make your heater work better. Does your truck have a Y at the heater hose on the front of the pass head? If it does you can block or restrict the hose returning to the radiator.
