Im chasing some bugs in my car. I think a coolant flush could help sort some things. I have a question though, my plan to flush is to removal the T-Stat and run 100% water for a few days with some of that flush cleaner. Plan to do it as many times till I get clean water out the rad. Then with a new T-stat put in some fresh 50% 50% and be done. Sound like a good plan? Also how do I bleed the system? And one last question, I see all the anti freeze on the shelfs say can be mixed with anything. I cant seem to find plan green anti freeze anymore (dex cool car from the factory). What should I look for in the stores?
