Dear Tom and Ray:

Thanks for your irreverent and uplifting oily and greasy advice! My question is one of timing. Timing belts, that is. I have an Acura Legend, four-door, midnight blue, with 110,000 miles. I have received three different opinions about changing the timing belt, and I want you to "disambiguate" them for me. I have heard: 1) It will break when you least expect it. 2) I've never changed mine and my car has umpteen thousand miles on it. And 3) It is a ruse to discover more things that need to be fixed. Please set me straight. -- Sam

Ray: Ah, Kemo Sabe. There is truth in all three of these [redtruck.gif] statements.

Tom: The timing belt WILL break when you least expect it. And on some cars -- including this and all other Honda products -- it will crush your valves and ruin your engine when it does break.

Ray: A small number of people get very lucky and go "umpteen thousand miles" on a single timing belt, just like some people smoke cigarettes and live to be 100. Can we explain it? Heck, no!

Tom: And some mechanics will suggest other work be done when you're changing your timing belt. The most common -- and most sensible -- suggestion is that you change your water pump at the same time.

Ray: So the answer to your real question (please set me straight) is yes, you should definitely change your timing belt now. The consequences for your engine are dire if you don't. And it's worth changing the water pump at the same time because you're already paying for most of the same labor.

Tom: Plus, since the water pump is run by the timing belt, if the old water pump seizes, it could break your brand-new timing belt. And wouldn't that frost your shorts?

Ray: Timing belts typically last about 60,000 miles. So if you changed yours at 60,000, you're due again at 120,000. If you didn't change it at 60K, then you're 50,000 miles overdue, and you should drive very gingerly to your nearest mechanic.

Tom: And think about this, Sam. If the belt were to break while you were on your way to get it changed, then all three of the above timing belt statements could be true for you, personally: It lasted umpteen thousand miles, it broke when you least expected it, and now the mechanic is going to use it as an excuse to sell you an engine rebuild, too.


It's NEVER cheaper in the long run to buy a new car. Want proof? Order Tom and Ray's pamphlet How to Buy a Used Car: Things That Detroit and Tokyo Don't Want You to Know. To order, send (check or money order) to Ruin, P.O. Box 536475, Orlando, FL 32853-6475. You can also order online.
