Do-it-yourself Pajero 3 repair

Mitsubishi Pajero of the third generation appeared in 1999, and became the "very first" three times in a row. Firstly, he became the progenitor of a new class - that is, a real SUV, in which the frame gave way to a monocoque body, naturally so strengthened and modified that one does not have to regret it. Secondly, the good old rear axle beam passed the baton to the fully independent suspension, which, as in the case of the monocoque body, was modified for real all-terrain needs.

Some can cite the example of BMW X5 or Audi Allroad, which appeared before, but they are not professional jeeps! Or cunning connoisseurs will remember the second generation Jeep Grand Cherokee, but there is the “frame in body” technology, that is, a masked frame in the body! So, Pajero 3 is unique, and does not consist of compromises. And thirdly, the "perpetual" distributed gasoline injection was changed to direct - GDI, Mitsubishi's proprietary system.

As part of this article, we will try to figure out how these changes affected reliability and whether Pajero lost all-terrain and other abilities. The third is the all-terrain ability of its predecessors, or vice versa, they have become better. It was sold, like its predecessor, under the names Montero and Shogun in different markets around the world.

The Pajero salon still looks almost modern today, and is made at the highest Japanese level, as a result, creaks and other extraneous noises do not increase with age. True, the leather from which the seat trim is made is not of the most exemplary quality, and their sidewalls were completely covered with a fragile leatherette. A spring suspension with adjustable stiffness was offered as an option for the front seats! Like on trucks!

About engines. Pajero engines are very demanding on fuel. It seems that the Japanese do not know, or have forgotten about the quality of something that is usually poured into the gas tank in our country, or ignored this fact, which is not like them! Whatever it was, in Russia they sold versions of cars only with direct fuel injection, that is, both gasoline with a 3.5-liter V6 gasoline engine of the GDI family with a volume called 6G74, and four-cylinder Di-D turbodiesels with a giant four-cylinder 3.2 liter volume under the name 4M41.

But with turbodiesels it is simpler, since they are rather low-boosted, and are designed for low-creeping fuel, then there are fewer problems with them. By the way, of all the competitors, both among the "pro" jeeps, as well as compromise and SUVs in the category up to 200 hp, only the third Pajero has the largest volume, namely 3.2 liters! Only in the late 90s and early 2000s there were 4.2-liter Land Cruisers 100 and Nissan Patrols, but they were not much more powerful, and even then, Pajero soon beat them in terms of power, traction and economy! Although the power is low, but the thrust is huge, that is, an excellent high-torque engine for a jeep! Developed from 158 to 185 hp. and thrust from 372 to 450 Nm. This superdiesel is still being assembled for Pajero, but in a form forced up to 191-203 forces. We also come across a variant that develops 165-176 forces. Its related engine 4M40, even a smaller version with a 2.8-liter volume, has proven itself well on the second Pajero. So, one should only be afraid of cars produced for the very first two years, because it happened that after 55-85 t. Km of run, their pistons burned out due to problems with the fuel equipment in connection with the quality of our fuel. Later, the engine was modified and the problem was corrected.

By the way, more reliable modifications with 2.5-liter turbodiesels under the name 4D56 from the previous Pajero, with a capacity of 99-116 hp were available on cars for the domestic Japanese market.They were usually combined with a simplified version of the transmission - Easy Select, and in addition, these engines generally do not care what to fill in the fuel tank. But you should know some features, and then the motor will serve correctly and for a long time. For example, one of the important things is to monitor the balancer shaft belt and change it in time, otherwise it may break off and fall under its “colleague” in the gas distribution mechanism, and this will lead to fatal problems with the cylinder head. For the rest, though not the most dynamic option in the city and on the highway, but if you keep track of everything on time, the diesel "runs" for a very long time. True, things are still better on the track, since the aerodynamics of the 3rd Pajero are better and this gives 5 km / h on the track, at such speeds, faster acceleration and fuel economy.

Let's move on to the most capricious version - the petrol "six" 3.5 "Dzhidai", that is DzhiDiAi (GDI). Here, direct fuel injection, and, accordingly, there is a high-pressure fuel pump on diesel engines, which is afraid of dirt and water in gasoline even more than its counterpart with a diesel engine, and cannot be repaired. Its price is $ 800-900. The first signs of this are the loss of thrust at medium and high speeds, or floating idle speed due to the clogging of the strainer inside the pump. True, its price is only $ 5-7. Even refueling exclusively at proven and reputable gas stations does not guarantee the absence of problems with this sensitive pump, and the dealers had to take the following measure: cut the fine filter into the fuel line of the under-warranty cars inside the pump in addition to the fine mesh. Also, you should pay attention to the injectors, since because of them, after 100-120 tons of kilometers, the engine of an SUV can work unevenly. It happens that washing, that is, cleaning, saves them. However, more often you have to fork out $ 2,100-2,500 to purchase six new injectors for the engine.

Also, bad fuel negatively affects the spark plugs, and here the caveat is that to replace each of the three of each V-block, you will have to remove the intake manifold from the engine, which means $ 180-200 with work. However, there is a silver lining, since the collector still needs to be dismantled from time to time in order to carry out cleaning, this is usually done every 45-60 tons. Kilometers. The fact is that the operation of the GDI engine at the "bottom" in urban conditions, like that of a turbodiesel, can lead to clogging of soot in the intake tract, and not only, but also in the throttle body and even on the valves. This bug is an inevitable disease of all "straight-injected" gasoline engines with a recirculation system, and in order to reduce its severity, the engine should be "burned" at high revs more often.

In the USA, where Pajero was sold under the name Montero, it had a 6G74 engine, which was a distributed injection familiar from the point of view of our fuel consumption, which, as a result, works even on our 92nd gasoline without much difficulty and consequences. On Montero, the timing belt with rollers should be replaced every 90 tons. Kilometers. This is $ 350-400 including work. During operation, there is a high probability of encountering the replacement of spark plugs and problems associated with the death of the neutralizer and the sensor of the "distribution" position every 110-150 tons. Kilometers.

In addition, in the Montero engine range, a simple but completely reliable version was produced with three-liter V6 gasoline engines (index 6G72), which is also known from the first and second generation cars. Power 150-182 HP Cars with such engines were also exported to the UAE, and since 2003 a 3.8-liter power unit with the 6G75 index, which later switched to Pajero IV without any special design modifications, although the "four" is just an improved, "refined" version of the third. By the way, this engine was the largest and most powerful V6 among both direct and "indirect" competitors.Judge for yourself, Mercedes ML and G had versions of the Mercedes 3.2-liter engine (211-218 hp), sworn friends of the Land Cruiser Prado 90 with 3.4 (178 hp), Nissan Patfinder 3.3 (150 hp) and 3, 5 (220-248hp). And finally, Padzherik with a 3.8-liter unit with a capacity of 216-252 hp! Only the 120th Prado has an even more voluminous engine - a 4-liter one, but that one is weaker (249 forces) and without bells and whistles such as phase shifters and direct injection.

Many growers are faced with a problem at the most inopportune moment the janitor stops, and only the driver's one, it measures in one place, when, on the other, the passenger continues to work in normal mode, when it happened to me, the first thought was about the slots on which the driver's wiper sits, I thought it spun and flew off the teeth, but upon examination it turned out that the janitor sits firmly in his place, but walks freely. Naturally, such troubles happen in the rain, and far from home, the rest of the way, about 30 km, I had to look into the passenger part of the windshield (for some reason I remembered Ace Ventura).

When I got home, I searched the Internet for the reason, it turned out that it was Pajero 3's "disease", which was also transmitted to Poggero 4 (judging by the reviews). There are a lot of indignant people on the forums, many the driver's janitor refused, and the refusal occurs in heavy rain, when the speed of the wipers is at maximum, at high speed on the road, it is fraught.

The reason lies in the fact that the worn-out plastic "cup" of the hinge falls out of the hinge under the weight of the thrust, after which the wiper stops, and the passenger wiper is not susceptible to such diseases, this is due to the location of the rods, the passenger cup rests on the hinge. and the driver's one hangs on it.

In the photo (not mine), you can see which rods the wipers are connected to, the location of the trapezoid in this photo is exactly the same as on the car, the arrow shows where the thrust of the driver's wiper falls, after the plastic bowl (or maybe the collet clamp) is worn out

Okay, I figured out the reason, you need to do something, the first thought is a repair kit for this trapezoid - there are no such in nature, seems to be suitable from some kind of cars, but I did not find anything like that in the car shop.

It turns out only the replacement of the entire trapezoid, I looked on the existential, I was upset. Nearly 7000 rubles for this piece of iron, of course, there are substitutes around 2000, but the question of how long they will last remained unanswered, plus the delivery time is 4 days, and we have rains and mud (spring in the Urals), and we need a car, a decision was made repair.

First you need to remove the trapezoid from the Pajero, for this, without opening the hood, unscrewed the screws (2 pcs), they hold the corner plastic pads, 5 by 5 cm in size, remove them.

Then he opened the hood, there you need to remove the caps that hold the plastic panel (black, corrugated, with a grill)

It looks like a piston under the hood of Pajero 3, I think Pajero 4 does not differ much after I pulled out the caps

You need to unscrew the wipers, there is a plastic black cap, and under it is a nut for 12, after unscrewing it. just pull the wiper off the splines.

I removed the plastic cover, now to remove the trapezoid of the wipers, you need to unscrew these 3 bolts, the same for the driver's wiper.

Next, you need to unscrew the thrust from the wiper motor, it transfers the translational movements from the engine to the trapezoid, it will have to be pushed a little in order to crawl to the nut.

Be sure to remember the position of this thrust, it is attached to the wiper motor shaft, I have it horizontally, the knee is retracted to the extreme left position in the direction of travel

After that, nothing holds the trapezoid. and it can be carefully pulled out, so as not to damage the heating wires of the rest zone of the wipers (who has)

It looks like a broken trapezoid the hinge came off, the janitor stood up.

Here is the same worn-out plastic fucking cup, similar to a collet clamp, the hinge itself is metal, then we will "modernize" it

It was decided to drill a hole in the hinge for a bolt, and twist the hinge together with it and nuts and washers.We drill a hole (we put one battery of a screwdriver, broke one drill)

Bolt hole ready

I inserted a bolt, pre-drilling a plastic cup, the hole size in it is about 8 mm, made so that the hinge does not lose its flexibility (hinge =)).

We put the washers and counter-control.

It turned out that the locknuts are not reliable, they saw off the excess with a grinder, and the bolt was flared.

Everything. The trapezoid was installed in place, everything about everything took 2-2.5 hours. Special thanks to my friend, Dimona, I could not have done it without him!
