To give cars more interior space while shrinking the overall size of the car, engineers have designed the engine bays as small as possible, with the minimum amount of clearances. That's why, for example, to change the serpentine belt, a lot of times you have to access it through the right front fender well, or from underneath the car. Plus, today's engines don't need anywhere near as much maintenance as before...one used to have to tune up the engine every 10,000 miles...now it's at least 100,000 miles or more before you need to replace plugs or wires. Service requirements are not as frequent. My '07 Edge doesn't need the transmission serviced until 150,000 miles. It will probably never need to have the plugs and wires changed. Everything is tied into the computer, which makes it almost impossible for the average person to do any work on the car.
My '97 LX with the Duratec has about 1" of clearance between the pullies and the inner fender. If I ever need to have something done, such as p/s pump, water pump replacement, I will pay my excellent local family owned repair shop to do it. They have the experience and tools to do the job correctly, and I don't have to skin my knuckles.
I do still change the oil and filters on my vehicles, though....and I have over 40 years of experience and knowledge to know what's what...experience gained by doing things myself...but, now that I'm older, and, can afford it, I let others do it for me.
I do have to say, though, that this site has been an excellent source of information on all things Taurus, and I thank everyone involved.
Having owned three Tauruses ('86 GL, '95 GL, '97 LX) I haven't found them to be any more or less than most other fwd cars in repair expenses. They are certainly cheaper to maintain then my '67 Lincoln was......
