The procedure is basically the same in all J Series engines, this is a universal DIY for it.

1.- You will need about 2-3 gallons of "Honda Genuine Anti Freeze Type 2" depends on vehicle.
2.- Put the Heat into max HOT while running and shut down the car.
3.- Remove the radiator cap and drain the antifreeze using the lower butterfly valve this will drain the radiator and most of the rubber lines in the engine.
4.- Behind the engine near the passenger CVD Shaft there is small brass fitting just left of the VTEC Solenoid near the engine oil filter, that is the drain plug for the Block (You will need to remove the Passenger wheel and a 6-7mm? socket to undo the block drain plug) this will drain the Heater Core and Entire engine block.
5.- Once the drain has fully bleed tighten the drain valve and replace the wheel.
6.- Pour the contents of the antifreeze into the radiator until it gets full, Now you can start the engine and start the burping process.
7.- Let the engine run until the fans kick in (around 5-7min idle) and keep filling the radiator as its removing the air.
8.- Once the radiator stops burping air bubbles close it and you are done.
9.- Replace the old Antifreeze in the Reservoir if possible.
