I was assuming a "cooling system flush" was always a chemical flush, where you flush it out with a special cleaner? The shops around here all generally charge around $100 for a "flush", but when I asked the shop that i chose to use (a shell station) if it's chem. flush he said no, that's about $20 more ($120). He said which one you want... I said i don't know which one i need. I told him it's been around 4 years since the the last drain/replace....then he quickly looked inside (opened the cap for 1 second) and said your'e fine, just get regular flush. so i did that. What's your opinion on this? Is a non-chem flush really any different than a drain and replace? (He said yes, because it drains it from the engine block as well as from the radiator???). thanks.
