I read over and over that everyone removes the lower radiator hose, some take the bumper off to do it because I guess it's a pain in the ass to get to.

I think I've got a better way to do it...

If anyone can think of some reason why this isn't better let me know.

Obviously coolant cycles in and out of the reserve tank at a pretty good flow rate. The upper hose is the incoming line.

I took the hose off the tank and added a fitting to add more hose to run into a container. As soon as I started the car up it started filling up the container. I'm confident I can add in my fresh coolant in while the old cycles out. Especially with a second person starting the car while I pour.

Thoughts on this?

I might just use water to start, wait until it's well flushed, then start pouring in full concentrate dexcool until I get about a 50/50 mix. (2 gallons)

Only thing that might jam me up for being able to get it all in one shot is the thermostat might stay closed.

So I did this at 200* no problem. Extended the incoming coolant tank hose (since coolant continuously flows through the tank while the engine runs.) and put the hose in a container. Plugged the hose nipple on the tank, put a funnel in the tank and put about 8 gallons of clean water through it. Then added in two gallons on Dex Cool concentrate. Done. No mess. No problems. Easy. Would never mess with pulling the bumper to get the lower hose off or whatever needs done.

If you were only looking to do a partial flush you can do it engine off, the funnel filled up pushes coolant out after it loops around the engine and radiator. It's not a 100% loop but it gets probably half the old coolant out no problem.

I did the heat exchanger the same way, pulled the out going hose off the fill neck, put a funnel into the hose. Ran more hose to a catch can. Turned the key on and the IC pump pushed out the old fluid while I added the new. So simple.
