Can I assume that using the Gooch coolant flush procedure is the same for my EX V10 gasser? My current coolant fluid, yellowish in color, tests 127/-22 but would like to flush and refill with the Zerex G-05 at just over a 50/50 mix, meaning approximately 4.25 gallons.

 

If the V10 has block blocks like the 7.3L PSD, then yes.

If there are no block plugs, then it will just take a bit longer to flush out the tap water.

Keep in mind your capacity will be different.
