What to do in which order

Ok I have a Sinister Egr cooler delete. vc-9 flush and a sinister coolant filter kit. My question is flush before delete then install delete and filter, or not risk the crap from the egr cooler coming loose and do delete then flush then filter? Also the car lot that I work at is doing the work and the parts department ordered the ford gold coolant. They said that was all the dealer knew about. Isnt that the stuff that causes the problems to begin with? I have a lifetime bumper to bumper warranty so I really dont care if they dont want to listen.

You want to use a Cat EC-1 rated ELC coolant. NAPA sells the Zerex ELC concentrate. Part# is ZXED1. If it isn't on the shelf have them order it for you. You will need 4 gallons.

I use prestone cat ec1 rated coolant. It's purple, and great for finding leaks should any arrise. I had a slight leak in my degas bottle FOREVER I couldn't find-once the purple prestone was in there, it soaked through and showed ALL the microcracks, including the one that was causing the leak!

Still doesn't tell me in what order to tell them to do the repairs but thanks for the input. They ordered the right coolant today and are supposed to be doing the repairs on it either tomorrow or Wednesday
