As I see it the orange coolent was used because it was supposedThanks Ed-I just became the 2nd owner of this 96 Roadmaster sedan with 63k miles in very good condition. Coolant has been changed according to the schedule but I've heard only bad comments about dexcool. Would there be any advantage/disadvantage in going from dexcool to the "green stuff"? Mike
Chances are you missed something like running a couple wires into the wrong plugs, or didn't connect the wires properly, or one of the wires inside boot connection could be off a little.I changed the spark plugs and wires on my 94 roadmaster sedan and now the service engine light is on can you tell me why?
