![]() If the cogs are missing, chunked out, or the belt has cracks or frayed edges, it needs to be replaced immediately.Įvery engine is different, but there are usually marks on the cam gears for the TDC position. But the peril is high, as you can easily get the timing of the cams wrong if you do not start with the engine in the correct position or if you move the cams during the process. The basic replacement is not difficult, just time-consuming. Replacing a timing belt is a moderate-level repair job. For most applications, you can get a complete kit with a water pump, gaskets, tensioner, and belt for less than $200-or the belt alone for less than $100. If it’s difficult to access the engine or the belt, the service can run more than $2,000. ![]() Cost to Replace a Timing Beltįor most vehicles, replacement can cost $500 to $1,100 at a shop. Outside of physical signs on the belt, you may have some issues with the engine, such as misfiring, black smoke from the exhaust, difficult starts, and an illuminated check engine light. Changing the belt when you are at or near the recommended interval is the best bet. The mark IS NOT lined up with the mark on the head in this picture.īut a timing belt can always fail without any outward signs, making preventative maintenance the key to a long-lived engine. This is critical for a correct belt change. This Acura 3.2 V-6 timing gear has a hash mark (shown at 1 o’clock) that marks the TDC point. Other engines have removable access covers that pop off easily to check the belt. It can be difficult to get to the timing belt to look for signs, as some engines have it buried under the front covers, accessory drive, and valve covers. Look for cracking, frayed edges, and missing or damaged cogs. While most belts will last beyond the recommended replacement interval, they will show signs of aging. ![]() Many timing belt kits come with a new water pump as well. When changing the timing belt, most manufacturers recommend replacing the water pump simultaneously. Check your owner’s manual to find the recommended change interval. Most timing belts should be replaced every 60,000 to 100,000 miles. Check your specific engine by make, model, and year, as most manufacturers use both engine styles. Non-interference engines do not damage themselves when the belt fails. This almost always results in a destroyed engine that requires a total rebuild or replacement. Why does that matter? If the timing belt stretches, breaks, or jumps a cog in an interference engine, the piston will most likely hit valves, which will bend or break the valve head and can break the piston. A non-interference engine is one where the valves can be fully open when the piston is at TDC. In an interference engine, when the valves are open, the piston can touch the valve at top dead center (TDC). There are two kinds of engines: interference and non-interference. It comes with a new belt, water pump, tensioner, and an O-ring gasket for the water pump. This is a timing belt kit for a Honda engine.
