I have a coolant drain plug that is stripped and stuck (passenger side behind starter). I am going to try and remove it, but wanted to replace it with a new drain plug. Does anyone know where to order one? Also, is there a Fumoto that will fit the 7.3L coolant engine block drain? I searched all over and I can only find information about a Fumoto for the 6.0L; I wasn't sure if the Fumoto was the same for both the 7.3L and 6.0L. Thanks in advance for the help!
I believe that plug is 1/4-18. You can buy them at a good parts store, and you might get lucky and find one at Lowes or Home Depot in their specialty bins.
I think the part number is 444619... "plug, 1/4-18" - That is what the diagram shows. There is another plug near the oil cooler labeled in the book as "plug, oil cooler drain, 3/8 NPTF" with part # 445684
Used an easyout, but the plug is destroyed. Got a new brass 1/4" 18 thread mpt plug, but doesn't seem to screw all the way in on either side of the block. May need to try and clean the threads on the block, may have some dirt/debris preventing it from going all the way in. Thanks again for the help!
