Here are the items you'll need for this procedure: drain pan, jack, jack stands, coolant

Remove the coolant cap before draining your coolant or lowering the level, as with the cap off air can flow through and let the coolant drain faster.

Raise and support your vehicle. We're using a lift to make it easier to show you guys what's going on at home, but this job can easily be done in the driveway or your garage with a jack and jack stands. Place a drain bucket under the front driver side of your radiator. There's actually a little drain hose tucked up here nice and neat. We're going to flip that down and hold it over our drain bucket while we loosen the petcock, and allow the radiator to drain. Be sure that your petcock is closed before refilling the coolant, and that the hose is folded back up into its holder on the side of the radiator.

Refill your coolant. This vehicle uses the orange coolant Dex-Cool. Make sure that it is either pre-diluted or if you buy concentrated full strength that you mix it 50/50 with distilled water. We'll fill it up as much as it'll take, and then back our vehicle outside to finish bleeding the system while it's running. Don't be afraid to overfill it, because once our vehicle runs and gets up to temperature the thermostat will open and that fluid will all go into the engine block.

Set your vehicle with the fan on the lowest speed, set to hot in the vents so you can feel the warm air coming out of the vehicle. This will also open any bypass valves that prevent coolant from entering the heater core when shut off. This is another place that air pockets can build up. Now we'll let our vehicle run up to temp, and keep the coolant topped off in the process.

Now we just had to add just about a gallon of coolant to the vehicle once it got up to temp. Now we'll keep an eye on it, wait for it to finish bubbling, our heat to get hot, and the level to stabilize before we'll finally top off our fluid and take our vehicle for a test drive. Once your fluid is finished bleeding, and it's topped off reinstall your cap and test drive your vehicle.
