coolant flush with g-o5

first off don't make the same mistake that i made there is a drain plug(bolt) on the block next to the water pump on the 5.9L (gas). use it
and your life will be easyer. It takes a long time to get the termostat to open,so open the block plug and drain the block before you do your clean water flush. If you use a flushing agent like i did drain the block 3 times. 1st old cooant,2 flushing agent 3rd clean water. Then refill and burp your system top off and your good for 5 years (don't forget to change your hoses) DMX recomends a HOAT coolant like Zerox G-O5 DMX uses g-o5 with a ornge dye ITS NOT DEX-COOL!!!!!!! You will know that you did it right when your coolant is yellow almost clear color.You can do it your self and change your hoses for less than most shops charge for a flush and refill
