Thanks for your inputs. I noticed the darker color on the port engine and decided to change it when I did all the other fluids on the both engines and transmissions. I used a prestone flush out system for each engine. Added water and ran it for thirty minutes then drained them and added a 50/50 mix of new coolant. Ran the port engine for about three hours and it's still a darker green? The other engine is lime green and looks great? Thanks! Gary
