Hey - Im looking to flush my coolant (primary only, no EGR) and so I am trying to gather some information on how it is done.
From what I have gathered on some posts here and other forums this is about how it works. Im trying to make sure i have the process down though.
1: drain whatever is in the primary system via block hose and pea**** drain
2: button up, fill distilled water in coolant tank/degas - aka reservoir - to MIN and fill rad tank.
3: run for 20ish minutes
4: drain distilled water in the same fashion as step 1
5: repeat X number of times until water is crystal clear
6: button up, fill with mixture of Ford OEM Orange AND distilled water. 50% orange, 50% distilled water
7: burp system(?) / ensure no air bubbles
7: Use a kit to test for that badbad.
The truck is at 83k but I bought it at 63k and it had an unknown background. The EGR fell off around 74k and the coolant was tested at that point. It came back good.
I expect to get some responses "why do you want to flush the coolant at 83k?" but i want to do it since i dont know very many details on the background of the vehicle and for my own peace of mind.
I called a shop to get a quote on what they would charge for it and they said $140. All my research says thats definitely just a typical drain and fill even though they tell me its not. The guy on the phone said "we drain it, fill it with a chemical bleach and cycle it with a pump, then we run distilled water through it and then fill it back up with coolant." Im not going to lie the posts ive found on here have scared me away from having someone else do this job.
Do i need the airlift vacuum system in order to do this at home? Do i need to cycle a chemical cleaning solution BEFORE i cycle in distilled water or no chemical solution at all - ive read mixed responses. Any feedback is helpful. Thanks
