Hi. I'm new to this forum and just purchased my first Mecury Cougar this past weekend. It's a 1999 with a 2.5 V6 with 105K on it. The car appears to be in excellent shape inside and out and mechanically there is nothing wrong with it. However, the previous owner did not keep service records. Therefore, I have no idea the last time the vehicle was tuned up. I would like to do a total tune up on it as soon as possible and was looking for some advice. I want to change the plugs, wires, cap, rotor, pcv, change oil, change transmission fluid, fuel filter, coolant system flush. Does anyone have any advice as far as the easiest procedure to change the transmission fluid or the fuel filter? Any advice on a good brand of plugs and wires? Any other advice is greatly appreciated. Thanks.
