A "professional flushing of antifreeze" is when a mechanic or other paid professional connects a hose assembly to your car radiator while at the same time opening the release valve (usually located at the bottom of the radiator) and forces water thru your car's water cooling system. The effect is to cleanse the system of old and rusted water and old antifreeze. This procedure is usually done just prior to adding new antifreeze to a car's cooling system, most often before the winter driving season. The end result being a more effective cooling system for the car. Hope this helps.
Power flushing?? Any kind of flushing of the cooling system will clean the heatercore. They both use the same source of antifreeze.
Your best bet is to visit a good auto shop (seller of antifreeze), and say "I want to buy enough antifreeze for a 1990 Chevy 5.7 truck".
I recommend flushing the system and replacing Dex-cool every 5 years or 100K miles.

Yes, you can add antifreeze / coolant to a car without flushing the radiator. It's best to use the same type that's already in your car / truck - conventional or long-life. Antifreeze / Coolant comes in 'Full Strength' which needs to be mixed with distilled water (usually 50/50 for mild weather regions, and more antifreeze 70/30 for really cold weather regions.) Also available is pre-mixed 50/50 antifreeze. PEAK Antifreeze & Coolant protects from -84 degrees to 276 degrees Fahrenheit when mixed 70/30. If it's been 2-3 years since a flush & fill for conventional antifreeze / radiator fluid, or 5 years for 'long life' antifreeze, it's likely time for a flush & fill.
there are other ways of flushing the antifreeze out besides the drain plug if the drain plug is jammed. for instance, loosen the clamp on the hose at the bottom of the radiator and pull the hose off. make sure to have a bucket or something large enough to catch all the fluid but small enough to fit under your vehicle. and watch out! it comes out fast!
The antifreeze should be diluted How much is up to you. Also be sure to configure in the location where you live (hotter, colder) as this also makes a difference I'm pretty sure that antifreeze needs some water to work properly (activates chemicals in antifreeze) If you went 70% antifreeze & 30% water you should probably be fine no matter where you live. ========================================================== Ford vehicles come from the factory with a 50 / 50 mix of distilled water and the correct type of antifreeze for the vehicle . Ford states not to exceed 60% antifreeze in the mix
If you find traces of oil in the antifreeze it's an indication of broken engine gasket. You need to go consult with a professional.
