=To properly flush the antifreeze on a 2002 Yukon you will need a antifreeze vacume system you will need to start the car and have it running turn on all the heating modules to high and have the car reved at about 1.5 r.p.m, or a little higher to activate the vaccume this will start sucking the old antifreeze out. When the radiator is empty{you will know when it is empty because there will be no more antifreeze coming out}you can then fill it up with half and half antifreeze[half water half antifreeze].=
To flush the coolant in a 2002 Toyota Echo you will need to drain it first. Flush with fresh water and then refill with coolant and distilled water.
You should re-fill with Dex-cool anti-freeze, if not; the aluminum inside engine may corrode.
It came from the factory with Dex-cool antifreeze.......added by haroldb. Don't use dexcool. Flush out your system and put plain antifreeze back in.. G M has a lot of law suits on dexcool
Purchase a PRESTONE flush kit, radiator flush, and new antifreeze. There is directions on package. You will be splicing a 'tee'into heater hose return line with a garden hose adapter,adding the flush to the radiator, and attaching the garden hose to the tee fitting. After running the engine for about 10 minutes with the flush in it, you will attach a garden hose to the tee and push all the crap right out the rad. Works good. Add antifreeze. Done. I hope this helps you. Mark
