1) drain the radiator, turn the car to on(not staring) and turn to max Heat.
look for a plastic winged plug at the bottom of the radiator

2) looking for the drain hole in the block, there should be one for 5th gen. Back of the block somewhere. take it off with a socket ratchet, let it pour.

3)take off the air bleed valve, hint* it should be in the highest point of the cooling system, mine location almost the top of my block.

4)optional-some people do flush it with distilled water and some dont

5) put the radiator plug back(change the rubber seal if it's running thin)
put the block drain plug back(dont over tighten)

6)pour in 50/50 mix coolant(60/40 if you live in extreme weather area/region) 50 percent coolant of your choice(peak>prestone) and 50percent "distilled" water. Running water have too much mineral in them, they "sand" down the aluminum parts in the engine and radiator in the long run.

OR

buy honda's pre-mixed coolant for the sake of simplicity

7) keep pouring until you see coolant rushing out of the air bleed valve.
(some people now turn their car on)

8) tighten the air bleed valve and dont forget to do a complete flush in 2-3 years.


remember to..

tighten all the hose clamps while you at it

pressure test the cooling system before and after(if the pressure would hole below 1.1 bar, dont try to put more pressure into the cooling system or you WILL have a leak somewhere)

pressure test the radiator cap according to the bar/psi reading of the cap.
replace if needed.

never use those radiator repair snake oil stuff, the often cost more harms than good

if i missed anything, or make a boo boo somewhere. Let me know
