5 Common Mitsubishi Triton 2.5 Diesel Problems

by | Aug 20, 2022 | Mitsubishi Problems | 0 comments

Are you the proud owner of a 2.5 diesel Mitsubishi Triton? Perhaps you are in the market for buying  a used Triton? If that’s the case, the following information might be useful to you.

The Triton has been roaming this globe since 1978, and it has undergone numerous facelifts and engine upgrades since then… The first versions of the software have not been as powerful as the present generation. The 2.5 litre diesel engine produces 100 kilowatt and 314 Nm. Triton engines are well-known for their long life, even if they are somewhat ordinary when contrasted to certain other vehicles of similar size.

They are extremely stable and, as a result of their extensive history, can be relied upon in many situations. Overall, the Triton has a positive reputation. Still, it’s a vehicle, and automobiles wear out and have problems.

Here are some common Mitsubishi Triton Problems:

The Triton has been around for a long, and while it isn’t your average class-leader bakkie, it is dependable and, to put it mildly, cost-effective. Nonetheless, it, like most other 4×4’s, has flaws. If you own a Triton or are considering purchasing one, you should be weary of these problems. Preventative measures are always better than a cure, and knowledge about them can help you spot potential problems before they become a problem.

1. Vibrations in the steering wheel

Let’s begin with the steering wheel vibrations. The steering wheel vibrates unnecessarily, and at times excessively. What could be the reason behind this? We hope it wasn’t because of the rutted road you were travelling on… most likely, if you’re not driving on a bumpy road, your shocks or suspension is to blame for any noticeable vibrations.

It’s possible that’s the issue, but it’s worth checking the steering column first. The column is normally secured with two bolts right beneath the dashboard. It’s possible that the steering column needs to be replaced, or that the steering wheel itself needs to be tightened. It’s not safe to have a tremor in the part that controls the entire weight of the car, therefore have it inspected and repaired.

2. The Engine Cuts Out While Idling

If you own a Triton, you may notice that the engine simply cuts out while idling. When you have random idling troubles like this, you might wonder if the problem is electrical or mechanical. It’s possible that it’s both. Check the turbo’s guide vanes for carbon build-up and make sure they’re not clogged. Carbon build-up in particular components can cause a slew of issues for vehicle owners. Make that the turbo diaphragm is clean, as well as the EGR valve.

While you’re at it, have a look at all the inlet vacuum pipes as well. Pressure sensors that monitor fuel flow through injectors may also cause the engine to stop at idle. Finally, clearing the ECU and recalibrating the injectors may help resolve the problem. If you ever find yourself in a situation where you’re stranded and can’t get to your destination, don’t blame the vehicle.

3. Changing gears is tricky.

Is it difficult to shift gears? If you’re having trouble shifting gears, whether it’s grinding or not going smoothly into gear, you should have the pressure plate, clutch plate, and bearings checked out by a reputable service center. A clutch, like any other mechanical device, is a “worn” part, meaning it will wear down due to friction. Some clutches may endure more than 100,000 kilometers, while others may not. If your Triton’s clutch is frequently failing, you may want to consider replacing it with a heavy-duty clutch, but this is a personal decision.

4. Power Loss

Have you ever experienced a massive loss of power while driving? This could happen for a variety of reasons. Is it possible that it’s due to a blocked fuel filter or a malfunctioning actuator? Perhaps it’s due to a failed turbo! Do yourself a favor and look over the turbo’s pipes and clamps. Also, make that the turbo actuator is opening the exhaust dump valve; you’ll need help with this, unless you’re fast enough to crank the engine, jump out, and check if it opens.  A drop in power could potentially be caused by the suction control valve. In common rail engines, the fuel pressure is controlled by a suction control valve.

5. Sluggish Turbo

What should you do if your throttle response is sluggish, other from experiencing a sudden loss of power? Now, let’s be clear: the 2.5 diesel isn’t a V6, but it does have some “turbo lag.” If you pull away or simply wish to accelerate and don’t have the power you expect, check the control valve again. Chipping that vehicle is an idea you might consider, something loads of Triton drivers have done. So, what exactly do I mean when I say “chip”? Let’s have a look at it.

If you ever feel that your Triton’s torque and power outputs are insufficient, don’t change vehicles; instead, have it chipped. After installing a Unichip, the ordinary Triton (as stated to in the beginning) gains 100 kW and 314 Nm of power and torque, respectively, to 115 kW and 365 Nm. Those are some excellent gains.

Triton engine outputs vary from 55 kW & 142 Nm for non-turbo engines to 131 kW & 400 Nm for intercooled 3rd gen variable geometry turbo engines. Whatever the situation may be, it is fair to presume that chipping your vehicle will result in a 15% rise in gains.

Finally, you may well have observed that Nissan purchased a 34 percent equity holding in Mitsubishi during 2016. As a result, Mitsubishi became a member of the Nissan-Renault international alliance. Parts availability and, in the not-too-distant future, part sharing are direct outcomes of this collaboration. Yes, there is sharing! Already, the newest Triton shares mechanical components with the Nissan Navara, and this trend will continue. Mitsubishi Motors’ chief operations officer confirmed that parts are shared for cost-cutting purposes rather than product-cutting purposes.
