The Thunderbird was parked 4 years ago. Now my son wants to drive it, and I am wondering what I should check/replace before putting it back on the road. Already replaced the radiator hoses, water pump, new battery, new tires, new serpentine belt. Going to replace fuel filter tomorrow, run sea-foam through it. The engine sounds fantastic, transmission shifts smooth, brakes look good. What else should I check/replace. Only problem found so far is the power windows, power antenna, radio work intermittently.
