Nissan KA24E and KA24DE engines
Content
Nissan ka24e are 12-valve engines manufactured by the company from July 1988 to January 1997. They favorably differ from their predecessors with a cast aluminum cylinder head, a forged steel crankshaft, cast steel connecting rods, and the presence of electronic fuel injection.
Nissan ka24de has been used in the creation of many trucks and cars. Most of the units were produced in Mexico in the city of Aguascalientes. The exceptions are ICEs marked U13 Bluebird, 240SX, 1994-97 Altima and FWD, which were assembled directly in Japan for cars produced in Australia.
The ka24de motor is very similar to the ka24e. In fact, it is its refinement, which, by the way, some mechanics are able to carry out in a car service. Ka24e has 3 valves per cylinder, which are actuated by rocker arms. In turn, the ka1de model is more advanced. It is already equipped with 24 valves per cylinder, which are complemented by a damper actuator above the bucket. Ka4de has multi-flow electronic fuel injection, and ka24e (its predecessor) is equipped with conventional fuel injection.
Depending on the place of assembly, the engines differ in some design features. An engine made in Japan has an interchangeable sump, an engine made in Mexico does not. Japanese internal combustion engines are equipped with a front oil supply sensor, a Mexican engine has a sensor installed on the side. The Japanese-made internal combustion engine has larger diameter journal bearings and a knock sensor.

Engine number location
The features of the ka24 series engines include the absence of balancing shafts. And this is despite the high power of the 2,4-liter engine. The cylinder blocks were made of cast iron and the cylinder heads were made of aluminum. In the ka24 versions, the designers used a crankshaft belt to replace individual main bearing caps.
Motor reliability
The reliability of ka24de and ka24e is largely due to the time of appearance. In the 90s, internal combustion engines originally from the land of the rising sun were distinguished by durability and reliability, combined with simplicity. However, like any other unit, they had their own characteristics. Front wheel drive ka24s can lose oil pressure if the sump hits an obstacle. In this case, the pan must be removed and the condition of the oil receiver inspected.
Nissan ka24de and ka24e do not like low-quality oil, which can “kill” the engine in the bud. The expected malfunctions in this case are the noise of the timing chain and other related symptoms. In some cases, it is enough to set the chain, focusing on the timing marks. In the worst case, a major overhaul or replacement of the engine is required. Regular maintenance using only high-quality oil will help keep your car out of trouble.
Occasionally, the idle system is adjusted. For what it is enough to adjust the operation of the engine with the help of an adjusting screw with a lock nut on the throttle rod. Everything is as simple as possible.
General maintainability
The maintainability of the Nissan ka24de and ka24e leaves much to be desired at the moment. As a rule, the main part of the problem lies in the untimely topping up of oil, which leads to engine seizure. Fortunately, it is not difficult to buy another contract internal combustion engine, and the prices are quite affordable. Of the other common problems, it is the replacement of sensors, for example, the same lambda wash, which is found pretty much everywhere. This kind of repair is more of a maintenance.
The components of the motors, if necessary, are changed to analogs from other manufacturers. For example, when repairing the ka24de distributor when replacing the ignition coil marked CM1T-227, you can use the Mobiletron CN-01 coil. Such an analogue costs 2 times cheaper, which, undoubtedly, pleases. There is no need to look for automatic transmission nw30 for nissan largo for a long time. Boxes 44 × 04 in a wide range are presented in the aftermarket, including options for spare parts.
Reviews on engines from the Nissan ka24 series are mostly positive. The reliability of the internal combustion engine is indisputable, which more than covers a small "gluttony". Moreover, not every car has high fuel consumption and is often associated with specific factors. The solution with the consumption of gasoline in most cases is found during the diagnosis at the service station.
Even inexperienced motorists will not be puzzled by the independent replacement of the valve cover gasket. The operation to help get rid of the oil smell in the cabin is as simple as possible. The cover that allows you to get to the old valve cover gasket and gaskets of the spark plug wells can be removed without problems. You can find the cheapest option on Chinese marketplaces by entering the query gasket.
Which oil to choose?
Ka24de / ka24e prefer only high-quality oil with the following markings: 5W-30, 5W-40, 10W-30, 10W-40. Owners of cars with similar engines most often prefer oil with a viscosity of 5W-40. In this case, the engine receives not only the necessary protection, but also the washing of parts. Oil with a viscosity of 10W-40 is used less often, as most users claim that the fluid is not suitable for viscosity, increasing the likelihood of coking. It takes an average of 3-4 liters. At the same time, the engine "eats" it mercilessly, so you should not forget about topping up. The fluid is replaced once every 1 thousand kilometers.
As for the choice of brands, one of the most popular is Castrol (5W-40). The main thing is not to stumble upon impudent fakes when frankly low-quality raw materials are poured into the branded packaging.
