I consider this one to be kind of a tricky/dumb question I hope you guys can help me out on this one.
2001 Grand Marquis's coolant capacity; now in order to add anti-freeze I should ideally apply 11 quarts anti-freeze and 11 quarts water so I can have a 50/50 mix. However I believe this is when the shop performs a TOTAL FLUSH.
Now how much anti-freeze should I put into radiator when we're talking about a stop and go - shop, so the guys at shop just let the anti - freeze go out with the engine still hot and fill in with new one?
thanks in advance
