Q You often talk about timing belts vs. timing chains. How can I tell which my car has, and when I should change it? We have a 2002 Nissan Altima six-cylinder with 106,000 miles, a 2005 Hyundai Elantra four-cylinder with 80,000 miles and a 2006 Hyundai Tucson four-cylinder with 15,000 miles. I'm sure the '06 is good for a while, but what about the others?

Q I have a 2007 Taurus with 100,000 miles on it. The manual recommends changing the antifreeze at 100,000 miles. Based on my previous experience, I am planning on changing the water pump and antifreeze at the same time. What is your opinion of changing water pumps before they fail?

Q My wife and I have a slight disagreement about our '02 Chrysler Concorde. I want to fix up the car with new tires, shocks, struts and a new timing belt. The car has 114,000 miles on it and has never had anything done to it other than brakes and regular maintenance. She says leave it and fix as needed. We have the money to make the repairs. What do you recommend?

Q The air conditioning has stopped working on my 1997 Grand Caravan. The van stalled and would not start for about 10 minutes. After that, the A/C would not work. Is there an easy way to tell whether the A/C clutch failed, or the compressor? I think the car stalled because the A/C seized up.

Q I have a 2000 Nissan Frontier pickup truck with the 3.3-liter engine. It has about 65,000 miles on it, and I'm getting poor gas mileage. The vehicle is rated for 19 miles per gallon on the highway, but I can't seem to get more than 16 mpg on the highway.

Q I'm thinking about buying a 2001 Buick Park Avenue that has been parked for about two years without being started. The car was properly maintained throughout its life and ran fine when parked but was not prepared for storage. I know the battery is dead. Does prolonged "parking" affect its value or reliability? What steps would you recommend to get the car started and running again?

Q I have a 2002 Olds Alero with the V6 engine. Recently I noticed that coolant is leaking. I have been told it is a slow leak from the intake gasket. My mechanic recommended that I get the leak fixed to avoid having the coolant mix with the oil. Is there a way to tell whether the leak is external or internal? If it's external, do I really need to fix it?

QThree guys in my neighborhood all have cars less than 10 years old. The first changes his oil and filter every three months with conventional oil, no matter what the mileage is. The second changes his oil and filter every six months, no matter what the mileage is, with synthetic oil. The third changes just the filter every three months and tops off the oil with conventional oil. He says the viscosity is what's most important, not the new oil.

Q I have a pair of '99 Cadillac DeVilles with about 166,000 miles on them that go through oil like crazy. I have to add oil twice a week. One of the cars smells like burning oil, and the other pushes whitish-gray smoky stuff out of the exhaust when I start it up that finally goes away after a few minutes. Is any of this normal? What should I do?
