COOLANT FLUSH/FLUID CHANGE
 

I NEED TO FLUSH THE COOLANT IN MY 02' 7.3 LIKE YESTERDAY :argh: CAN ANYONE TELL ME HOW MUCH FLUID THE RADIATOR HOLDS AND HOW MUCH THE ENGINE HOLDS? ANY HELP WOULD BE GREAT :c:

About 4 gallons... I cant remember for sure but if you get 5 it will be plenty.

one more question i just want to make sure it takes just regular 3 year coolant? this is my first diesel but ive owned it a year now, just trying to catch up on maintenance because i have no idea if or when it was ever done

coolant flush
 

i just flushed my coolant recently and changed the block heater. i would rec-amend that you pull the block heater to drain coolant form engine. otherwise you wont get a full flush.

alrite, which side of the block is the block heater on? and bout how much does it cost to just replace the heater too? i have no repair manuals or anything on this truck and havent had my hands really in it yet, so im kinda just wingin it haha

the block heater is right above the oil filter on the drivers side. it has a cord running out of it and you have to make sure the coolant is cold. i repeat has to be cold. drain all coolant from radiator. then when you remove the block heater you will only get whats left in the block as far as coolant that will drain out. coolant will drain rapidly out of the block heater hole. i went to ford and it was 64 bucks for the heater, its such a pain draining all the coolant so its best to just make sure you have a new heater so as to not have to do this again in the near future. i had to replace my block heater cord as well and they run a little bit more, around 110$.

ok cool thank you for the info. ill check on some prices and see how bad it is to do the block heater..i know it works as of last winter but if thats the only way to get the coolant out of the block than it looks like ill be buying the heater too.

thanks again :choochoo:

there is a 1/4" NPT drain plug on the passenger side of the engine. towards the back and a few inches above the oil pan. also, ford says you need to use a special coolant additive from ford or the coolant can pit your block. i don't know if this is true but i don't want to find out the hard way.

there is a very good additive that all the big trucks use. i get mine at fishers auto parts but i think its available at napa...its suppose to give your antifreeze the proper freezing/boiling points back to new. idk if it works, but my buddy has tested it and says it does whats it supposed to do...

why would you need an additive if your PH is normal
