best way to remove block coolant drain plug on D series?
Location of this fu**n plug is horrible, anyone with a suggestion what to use on it to get best access and leverage? tried some from underneath but no luck ... engine is d16y7 with top feed TB so maybe for a better acces I should remove the filter box? HELP :d ... I know it's stupid but i want to do job right not just half ***

really???????
My D15B7 and D16Z6 had the drain plugs on the FRONT of the block.
Look down between #3 and #4, that 1/2 head you see behind the webbing on the front of the block is the drain plug
D16Z6
D15B1/2/6/7/8 = in front of #3

Ahahaha, coolant drain plug!!
Just remove both rad hoses from the block, thermostat, and the petcock from the rad.
Stick a garden hose in top radiator hose until clear water falls out the bottom of the radiator, then do the same with the bottom rad hose. That'll clean both rad hoses and the radiator.
Turn the ignition on - set the heater to "heat" so it opens the heater valve. Then turn it off. Stick garden hose in hole on top of block, let it sit for 10 minutes. That'll clean the block and heatercore - if you're really self-conscious about it - after you turn on the heater and are running coolant through it - start it up and let it idle for a few minutes, just watch the temp gauge.
Put it back together and fill it back up.
LoL - Removing the header....coolant drain plugs..impact wrenches....ahahhaha....

Re: best way to remove block coolant drain plug on D series?
1.) Remove petcock from radiator, located at the bottom of the radiator passenger side(assuming the vehicle is left-hand drive). The petcock should be finger tight and easily removable with your finger. Allow as much nasty coolant and water to drain out as possible.
2.) Once fully drained, reinsert petcock into radiator and tighten ONLY USING HANDS. NO TOOLS!!
3.) Remover the clamp on the upper radiator hose. Either side is fine, whether from the radiator or from the engine block.
4.) Once hose is undone, turn on vehicle and allow to idle until temperature needle begins to rise. Make sure to turn the heater on up to maximum capabilities. You may speed up the process by increasing the RPM's. However, once it begins to rise, let idle, get out of the car and turn on a hose with fresh, cool, constant flowing water.
5.) Leave driver window open and watch the temperature gauge. ONLY when the needle reaches the middle of the gauge AND ONLY THEN will you jam the hose into THE RADIATOR!! Water will then flow through the radiator, past the open thermostat, through the heater core and all the other filthy coolant lines of the car. You will be able to see this gunk coming out nice and warm/hot from the cylinder head where the upper radiator hose connects to. Try to create pressure with your hose by making sure it is sealed and water is not back flowing onto your hand. Try to make sure EVERY DROP goes in through the radiator and out the motor. The temperature may go down quite quickly. Continue this until the water coming out the motor is basically clean and clear.
FOR BEST RESULTS, REMOVE THERMOSTAT AND PUT HOUSING AND HOSE BACK TOGETHER CAREFULLY WITHOUT OVER TIGHTENING!! ONCE FLUSH IS COMPLETE, OPEN HOUSING AND RETURN OR REPLACE THERMOSTAT. BE CAREFUL WHEN RE-TIGHTENING THOSE BOLTS!
