Default Coolant Flush

I know this has been brought up but I don't want to use the flush and fill kit as I don't want to cut into any hoses. How can I do this with out the kit? I will be doing int on my 2003 and my bro'* 99 sle. Can I just pull the drain plug on them then fill with some water(we have warm and cold in the garage) let it run drain it again then put the proper coolant in?

But the lower hose isnt all the way at the bottom of the radiator...at least not on my SSEi. Which I dont like cause there is still some in the bottom. I thought I read somewhere that you can use the knock sensor as a "plug" and drain from there? I need to do mine really bad but may end up waiting and just take out the radiator when I do my LIMGs.

I refilled mine with water and drained it again 4 times. and ran it till hot on each refill. That got most of it out.

Default flush

I disconnect the heater hose from the engine, insert flushing tee, use piece of scrap hose to connect tee to engine and flush. Remove tee & scrap hose when done, reconnect original hose to engine.

Default flush

The backflush should be done through the heater hose, not the radiator hose and they use a common 3/4 hose tee which is included in the flush kits.
