The Car Guys, Tom & Ray Magliozzi, say ‘Regular Maintenance Helps Prevent Big Issues’
Courtesy Acura’s Concierge Delivery Expert, Lou Taylor, found a helpful Q&A article in the Denver Post that addresses the question of how important regular maintenance is when it comes to your vehicle and more specifically your timing belt and water pump. The Q&A is answered by The Car Guys, Tom and Ray Magliozzi (the co-hosts of NPR’s weekly radio show, Car Talk). In the article, Tom and Ray discuss an avoidable issue we commonly see in our service department. That is, ignored timing belts and water pumps that end up causing extreme damage to vehicles at a much higher cost to the owner than the routine maintenance. To avoid costly repairs caused by neglected timing belts and/or water pumps, read the full article below.

Regular maintenance helps prevent big issues
The Denver Post – January 3, 2015
The Car Guys: Tom & Ray Magliozzi
Q: Dear Tom and Ray: When driving down the freeway, I heard a scraping sound, shortly followed by my car slowing down, no matter how hard I pushed the gas. I barely made it to the service road without getting hit by other traffic. When the tow truck driver came, he noticed green liquid (coolant) leaking out. The mechanic towed the car and said my water pump had frozen, and that broke my timing belt. He said it was the first time he had ever seen it, and he doesn’t know of a way I could have avoided it. I need to know if it was something I did, that I can avoid doing in the future. I am paranoid about he situation and worried that it will happen again. Thanks! -Joanna
Ray: It does happen, Joanna. But we like when it happens. For us, it means we won’t have any trouble making our boat payment that month!
Tom: You don’t tell us what kind of car you drive, but I’m guessing it’s something with a non-interference-style engine. Cars with interference-style engines get ruined when their timing belts break. It sounds like you were lucky and you avoided that grisly fate; you got off with just an expensive repair and severe travel disruption!
Ray: The vast majority of manufacturers recommend that you change your car’s timing belt after a certain number of miles – 60,000 miles used to be common. Now lots of manufacturers suggest 90,000.
Tom: If you don’t change the timing belt, it can break down on its own due to age and use. But on almost every car we see, the timing belt also runs the water pump (which circulates coolant in the engine). In other words, the timing belt goes around the water pump pulley, and as the belt turns, it makes the water pump’s impeller spin. If the water pump fails, and seizes up, like yours did, it takes the timing belt with it.
Ray: So to prevent this in the future, you have to do a better job of maintaining your car, Joanna.
Tom: For instance, it’s possible your water pump was failing and you just didn’t notice the horrible growling sound coming from your engine compartment. Or you don’t see a mechanic regularly, so no one else had a chance to notice it.
Ray: Or maybe you were a good car owner, and you had your timing belt changed when it was supposed to be, but to save a little money, your or your mechanic didn’t change the water pump at the same time. That’s penny-wise and thousand dollar foolish, in our opinion.
Tom: Yeah. We’d never change a customer’s timing belt without changing the water pump, too, for the very reason that caused you to write to us — that’s what can happen. And then they come back and blame us for it!
Ray: Also, we tend to use factory water pumps rather than aftermarket pumps for this repair, because the risks, if the water pump fails, are so severe.
Tom: So, how do you prevent this in the future? Get better about your regular maintenance. Find a mechanic you trust…and take your car in on a regular basis. Even if it’s just for an oil and filter change every 6 months, at least someone has a chance to notice when something is going terribly wrong.
