Easiest way to remove most coolant

[Ahsai]

Hi , I plan to change out my coolant and just want to find the easist way to do that.

I plan to drain from the coolant drain plug on the engine, then disconnect the lower coolant hoses from both radiators.Would this work? Total capacity should be about 6 gals and I hope to get at least 4 gals out with this method.

TIA

When you replace your waterpump, as you are now due. And the thermostat.

Yes, I already bought those parts (a low temp version). I just want to replace as much coolant as I can at the same time.

Good job! When mine was done in late September, the indy replaced just over 4 gallons total. I did a few small "top-ups" with distilled water. Make sure you purchase 2-3 gallons of distilled water from the grocery store.

Already did but thanks:) Car is an '03 with 55k miles. Thinking whether to replace the idle pulleys. No free play but some gritty sound. They are expensive for a pulley...
