Nissan Maxima Timing Components
The Nissan Maxima is a luxury sedan with a roomy interior and excellent safety scores. Top-notch safety features aren't enough, however, if the engine isn't in good working order. One essential component that keeps your car running smoothly is the timing chain.How does engine timing work in the Nissan Maxima?
For car engines to operate at peak performance, every part has to work at timed intervals. This sequence is controlled by the timing system, which ensures that each part rotates at the correct time and speed. The following parts are involved:
- Timing Belt or Chain: The timing belt or chain runs throughout the entire system. Most Nissan Maxima models are equipped with timing chains, which are made of metal and tend to last longer than belts. It is responsible for keeping the other parts in time while the engine is being operated.
- Timing Chain Tensioners: Tensioners keep the timing chain in place as it progresses through the vehicle. They ensure that it is pulled taut and that it never slips out of sequence. In the Nissan Maxima, tensioners are usually controlled by oil pressure.
- Pulleys: Pulleys are responsible for guiding the chain throughout the vehicle.
- Camshaft and Crankshaft: When a Nissan car is operating at the correct time sequence, the crankshaft rotates twice for every one spin of the camshaft.
- Pistons and Valves: The relationship between the two shafts determines the movement of the pistons and valves. If they don't open at the precise time intervals, the Nissan mechanical system will fail to function.
While timing chains are very durable, they aren't immune to mechanical malfunctions. The other parts of the system can also get old or break. Here are some signs that this system is in need of repair:
- Sluggish Performance: If the problem is the timing chain itself, Maxima drivers will notice a difference in driving performance. As the timing chain ages, it starts to stretch out, which slows down the related operations. This leads to sluggish driving, starting problems, and low power situations.
- Noises: When the system parts start to fail, drivers may hear buzzing or whining noises coming from the front of the vehicle. This is caused by the rattling of the stretched out timing chain as it moves through the system.
- Misfire or Sputter: A car with an off timing will sound uneven. If one or more of the spark plugs are firing at the wrong time, the sound will not be universally smooth.
