Best cost-effective way to do it, IMO, is if your system is clean and not giving you any problems but it’s time to change coolant, then simply drain from radiator petcock. Fill her up with water, open both bleeder ports up top to bleed air and close them when full (one by the radiator one near the valve cover).I am curious as to when your flush is done, which hoses are you disconnecting to make sure you have the engine and radiator all drained out? I will be doing a coolant change on mine soon and could use all the pointers I can get. Also my rig is new to me and may have never had a chemical flush or anything like that. What would be your recommendation? Flush with just clean water or run a chemical treatment of some kind?
Cover radiator with cardboard, Crank truck, let it run for 10 minutes, then bring idle up to 1500rpm and hold there for atleast 20 minutes then drain it off into 2 clean 5 gallon buckets, inspecting for sediment and scale. Depending on if you have some come out or not, will determine how much flushing you’ll need, and whether you’ll need chemicals or not. If the coolant is in good shape, no chemical needed just water, if it’s failed and gummy you’ll need something to break it up, if you have a ton of scale, then you need a radiator descaler
Honestly, despite being so nasty I’ve yet to pull a radiator hose, my plans are to run a descaler solution through to dissolve any rust and scale whenever i get all this oil out
