DIY: How to flush your GS2 coolant with pictures
#16
How do you...
I'd add a couple of pointers/caveats.
First, the red coolant is Long Life, not Super Long Life as stated up top. I'm not trying to be picky, but it confuses even some parts guys I talked to - the Long Life (red) coolant is pure antifreeze, the Super Long Life (pink) coolant is already diluted to 50/50. So just be careful that you get the right one.
Next, when you say "pour all of the red coolant into the radiator", you should clarify that you should pour half of the system's total coolant capacity into the radiator. Since the total capacity is 10.4 qts, you should pour in 5.2 qts of red coolant, and then top off with distilled water to get the 50/50 mixture. Don't forget the overflow reservoir, some of the coolant should go into that too.
I would drain the block too, as it holds a lot of coolant that does not get drained by just draining the radiator.
When running the engine to flush the system, have the heater working to get that purged out as well.
In my experience, it took several drain and refill cycles to get all of the old coolant out, i.e. before the drained stuff came out clear and not red or pink. If you know that your current coolant is not contaminated and is Toyota red, you can probably get by with doing one or two drain/refill cycles. But if you don't know whats in there now, I'd repeat the drain/refills until the water drained clear.

What I do also is after im done filling up the radiator back up, I rev the motor to about 1500 rpm with the cap off for 15 to 20 seconds at a time. I do this for bout 4 or 5 minutes. Hope this helps.

Dont recall every seeing this....good little DIY. nigel should add it to the stickies. when i do mine next year (did it awhile ago already) i will post the pics of the engine block bolt.
one question though...i see lyonkster said total capacity is 10.4 quarts but is this including the coolant in the block? i would assume so since he says total capacity but i just wanna double check.
i gotta go look up the recommended interval change on this also, will do so when i get to work tomorrow less someone wants to post it....off to bed now
EDIT: found it, every 30k

Btw...does anyone have a pic of the drain on the engine block? I assume the location of the drain on the engine block is different on the 300, 400, and 430.
Great writeup with pics...thanks for sharing.

Yup, 10.4 is the total capacity; radiator, block, heater core, hoses, etc . So if you are only doing drain and refill of the radiator, you'd adjust accordingly (i.e. measure how much you drained, then put in equivalent amount of 50/50).

i wonder how many times i would have to do this being that the previous owner used the
green coolant and i dont know for how long.Do you guys think i should just continue using
the green or flush it out and put red?

Nice.
Ive never used these, but the concept sounds great to flush out the system and flush out all deposits and sediment.
You cut the coolant hoses, put one of these inline and then flush the system with a water hose.

If you are into flushing with distilled water and want to retain the stock look of your hoses, then the "T"-flush system is not for you....

There's lots of posts on whether to risk mixing the "Green" with the "Red", since each has differing additives...and some say risk of sludge formation and/or aluminum pitting.
If you plan to go Toyota Red or Pink, the good DIY'er should do it right, and completely flush or do multiple drain'n'fills until clear...then refill with the right mix of either Red or Pink.
Do a search for antifreeze on the CL forums, especially the maintenance forum for all the lively banter of conversation there...
