How To: B15 Rad Flush
its not that hard, considering i had never done it and called around shops were charging $90-190 + materials/fluids at some as well
Materials
1 Jug of green coolant (don't get the mixed/premixed or anything like that, the newer stuff has some corrosive materials in it, do it right the first time)
1 Jug of deionized water
mix them 1/1 that'll give you the correct ratio and -37 celsius usage (good for up here!)
Tools
friends with beer
8mm 10mm socket
(i replaced my lower rad hose cuz it was leaking $18 @ stealership - cheaper than any parts store, very surprised)
bucket to catch your used fluids
garden hose
Instructions
on the bottom of the rad there is a butterfly (plastic - make sure when you tighten back up not to over tighten), loosen and drain all the fluid out
from top
from bottom
release the lower rad hose beside butterfly screw, let drain whatever else from the engine comes out
take your rad cap off and put your garden hose in there and flush it out with water
next take the rad hose off by the rad cap and flush out the engine with the garden hose as well let drain
now before the the fun
remove your over flow jug on the left side of the engine bay
there is a screw at the bottom near the front of it and drain that puppy out with the garden hose as well, put back when done
now you're all drained turn your car on so the thermostat opens up so all the fluid can run through the engine
there is a engine air plug that should be opened now so there will be no air bubbles when pouring in the new rad coolant you mixed earlier
put all your hoses back and screw the butterfly plug back
you'll need about 6L of your mixed fluid to put back in through the rad cap entry, pour slowly no need to waste, if you get bubbles then take your time
after it won't fill no more or you're close to your 6L close that engine air plug back up
turn the car on and let it run and suck all the fluids through the rad, turn your heat on full blast it will blow cold for 15mins when hot then you know all the fresh fluid had gone though and you are complete
go for a drive and check the overfill jug if it has taken any and keep an eye on it for a couple days
since i've done mine i've maybe added 1 cup of mix
now where's those beers?
