If your vehicle has more than 70,000 miles on it, there’s a hidden danger you should know about. It’s a small part that’s wearing out, and if it breaks before you replace it, it could destroy your engine. We’re talking about the timing belt. It’s a sad but common tale: someone’s driving down the road, and the belt snaps. The car stalls and won’t restart. A tow truck hauls the car to the auto repair shop, and the driver discovers it will cost $2000 or more to rebuild the engine. It’s common because it happens to a lot of people; it’s sad because it’s so preventable.
