i was wondering how much coolant my 92 7.3 idi holds i just found out from the previous owner that when they did a coolant flush last fall they didnt put any water in just straight antifreeze they thought that it would be better for it because it sat all last winter luckally the block didnt crack i just need to know how much to drain out and replace with water thanks
I just did my 1993 the manual said around 7.25 gallons and i thinks thats with the overflow being filled. Also make sure to add sca's if it doesn't have them yet.
i just told the guy at napa i needed the coolant additive for diesels to protect against cavitation if i remember right it is called napacool or something like that
I don't know on the 7.3's maybe somebody should investigate this, but on big diesels they claim having too much additives is as bad as not having any so we use the test strips and add accordingly.
I have wondered if using a water filter like we use on the big rigs would help.
