Nissan Navara is an excellent truck and comes with remarkable off-road capabilities. It is powerful, efficient, and reliable. However, like any other vehicle, it is not immune to engine problems.
Nissan Navara models that have severe engine problems include the D22 or D40. These models have YD25 engines (2.5-liter diesel) and have problems that you need to know. Most common Nissan Navara engine problems include chain stretch, Coolant Leak (EGR), Exhaust Gas Temperature Sensor, Transmission Cooler Fault, and Turbo Failure.
Engine problems can be pretty expensive to repair, but some can be avoided with proper maintenance. In this article, we will discuss the most common Nissan Navara engine problems and their solutions.
6 Nissan Navara Engine Problems and Solutions
Navara engine problems can be severe and cause your vehicle to stop out of nowhere. Rather than stressing over it, just pull yourself together and check out this guide.
Here are the 6 most common Nissan Navara problems and their solutions:
Chain Stretch/Faulty Timing Chain
Problem: One common issue with the Navara is chain stretch, as the YD25 tends to stretch. This can cause the engine to run rough and eventually lead to engine damage if left untreated.
The timing chain keeps the engine’s valves in sync with the pistons. It also guides the vacuum pump timing chain which helps control engine oil pressure. A faulty timing chain may cause the pistons and valves to collide, which can cause serious engine problems.
Solution: The best solution is to replace the simplex timing chain before the 100,000 km. Also, you need to take it to the mechanic shop after every 40,000 km for a checkup and make sure that the chains are still in good condition.
Coolant Leak (EGR)
Problem: In the Nissan Navara YD25 engine, the Exhaust Gas Reticulation cooler may split or corrode, which can cause a coolant leak. The most common symptom of this problem is the engine overheating.
Due to heat, the coolant may start evaporating and can’t see pooling under the vehicle. The coolant loss can also result in damaging the cylinder head gasket.
Solution: You should regularly check for your Nissan Navara coolant level if there are any stain marks around the cooler and EGR pipe. You need to replace the EGR cooler and gasket to fix this problem.
Exhaust Gas Temperature Sensor
Problem: The exhaust gas temperature sensor in Nissan Navara is more prone to failure, and it can cause the engine to enter a limp mode. This way, it helps to prevent engine overheating of the turbocharger.
A faulty sensor may also cause the engine to run rough, and the check engine light will illuminate.
Solution: If you are experiencing power loss or your truck is going into limp mode, then you should get it checked as soon as possible. In addition, get your fuel pressure valves checked because a lack in pressure of fuel can also put your truck into limp mode.
Transmission Cooler Fault
Problem: Navara’s automatic transmission cooler is located in the radiator. It may get blocked by debris, which can cause the transmission fluid to overheat. Also, the Navara’s radiators are known to burst internally for several owners. It depicts that the transmission cooler is not the only problem, but the radiator can also cause a nuisance.
In addition, your engine coolant can have a route to an automatic transmission, hence you can also lose function in your reverse gear.
Solution: The best solution is to get your Nissan Navara’s transmission flushed and refilled with fresh fluid. You should do this every 40,000 to 50,000 km. In addition, you need to check the radiator for any sign of leakage and get it replaced if necessary.
Fuel Pump Failure
Problem: Navara’s fuel pump may fail over time due to corrosion. It can cause the engine to stall and struggle to start. In addition, you may experience a loss in power, and the engine may misfire.
Solution: The best solution is to clean the fuel tank and the fuel line. You can also try to replace the fuel filter. If the problem persists, then you need to replace the fuel pump.
Problem: The turbocharger is responsible for providing the Navara with extra power. However, it is also one of the most common problems in this truck. The turbo may fail due to a worn-out bearing or a clogged oil filter. A lack of oil change can also cause it.
Solution: The best solution is to get the turbocharger cleaned or replaced. You should also get your oil changed after every 5,000 km.
If you are experiencing any of the above-discussed Nissan Navara engine problems, don’t hesitate to get in touch with a qualified mechanic who can help you fix the problem. With a little bit of care and maintenance, your Navara will be back on the road.
If you are trying to fix the issue yourself, you must be sure about what you are doing and certain about it. Otherwise, consulting a mechanic is a good idea to avoid complications.
Are Nissan Navara engines reliable?
Yes, Nissan Navara engines are reliable. All of its parts are well proven, and the 2.3-liter diesel engine is one of the most reliable ones. However, you may face issues with the Navara engine, but on-time maintenance and proper usage will help you keep your engine healthy for a longer time.
How long do Navara engines last?
Nissan Navara engines are designed to last for a long time. However, the life expectancy of a Navara engine depends on how you use and maintain your vehicle. A Navara engine can last around 350,000 to 450,000 km with proper engine servicing.
What are the common problems with Nissan Navara engines?
The most common problem with Nissan Navara engines is the timing chain stretch. This can be avoided with proper engine maintenance. Other common problems include coolant leak, EGR sensor failure, and turbo failure.
