Which is more Importance: serpentine belts or timing belts?īoth serpentine belt and timing belt has different jobs and each are required for unique reasons. Loss of engine power- if the belt slips off snaps or pulleys, the engine can misfire or lose power. It can reduce the engine oil pressure and end up with engine failure. Low oil pressure- the teeth of the timing belt may break off and drop into an oil pan. Rough idle- the timing belt may slip and encourage the ignition timing to run out of sync if some of the teeth break down.
Since replacing the serpentine belt is easier and quicker, it’ll cost around $300 for the job including labor. It requires different time and effort to repair or replace the serpentine belt and timing belt which is reflected in the maintenance cost. A serpentine belt is relatively cheaper and easier to replace. But the engine will overheat quickly without the water pump, so you can’t drive very far. So you can drive the car for a short distance. If the belt breaks down, the engine won’t self-destruct immediately. Since the serpentine belt is external to the car’s engine, it doesn’t hurt the engine severely if gets damaged. If the timing belt fails, the engine may self-destruct in most cases. The timing belt also remains hidden in the engine and can’t observe if it wears out or gets sludge due to using the wrong oil or following a poor oil changing policy. Though the timing belt isn’t expensive, the tiresome replacing process makes it costlier to handle. So the engine can hit the open valves while turning and can get damaged. Some engines are also designed in such a way that if the timing belt breaks down, the camshaft won’t turn. Due to the placement behind a cover, the timing belt takes lots of labor to replace.
The timing belt turns the camshaft with operate the valves. But the timing belt will take tiresome effort to become visible. So you can easily see the serpentine belt after popping the hood. The serpentine belt is placed outside the engine and the timing belt is usually located inside or behind the engine. Otherwise, the camshaft may activate the firing orders of spark plugs and crankshaft cycles won’t respond to each other. The timing belt should be lined up with the crankshaft gear’s dot marked. Timing belts and chains maintain precise ratios by utilizing cogged pulleys and corresponding notches on the chain or belt’s inner side. Failure can occur if the ratios are interrupted. Timing belts deliver rotary motion to internal engine parts and maintain accurate ratios between the camshafts and crankshafts to avoid engine damage, bad piston, and bent valves. Slippage is also allowed as various systems aren’t needed to maintain precise ratios with the engine rotating parts. It includes a power steering pump, oil pump, alternator, supercharger, vacuum pump, water pump, and A/C compressor. It is driven by a crankshaft pulley and delivers rotary motion to run various power accessories bolted on the car’s engine. The serpentine belt connects the engine to various components of a vehicle like the alternator. Noise, rough idle, low oil pressure, loss of engine power Noise, wear out, Glazed appearance, too loose or tight Maintain accurate ratios between the camshafts and crankshafts The serpentine belt and timing belt isn’t the same thing and they have huge differences in terms of their design, appearance, and purposes.īefore deeply discussing what is a serpentine belt vs timing belt, let’s take a quick look at their key differences: FeaturesĬonnects alternators, A/C compressors, and water pumps to the engine Serpentine Belt vs Timing Belt Key Differences Is the serpentine belt the same as the alternator belt?.Can an engine run without a timing belt?.Should you replace the serpentine belt when replacing the timing belt?.Which is more Importance: serpentine belts or timing belts?.When should you replace the Car’s Serpentine and Timing Belts?.Serpentine Belt vs Timing Belt Key Differences.
