1990 Nissan D21 problems
The Datsun Truck is a compact pickup truck made by Nissan in Japan from 1955 through 1997. It was originally sold under the Datsun brand, but this was switched to Nissan in 1983. It was replaced in 1997 by the Frontier and Navara. In Japan, it was sold only in Nissan Bluebird Store locations.
Predecessors
Pre-war
The Datsun truck line began with the Type 13 Truck of April 1934, and was later used as the basis of the Datsun DC-3 roadster. A series of small trucks based on their passenger car counterparts, the 14T, 15T, and 17T, continued to be built until early 1944.
Post-war
The 17T was followed by the post-war Datsun 1121 in 1946, which was nearly identical technically but had an extremely simple body made out of simple pressed metal (with almost no chrome) and many body parts made from wood, to enable production in resource-starved early post-war Japan. Early trucks also depended on leftover stocks of pre-war parts. The engine was the 15 PS (11 kW) Type 7 unit. As the supply situation improved the new 2124 and then 2225 took over in July 1947 and at the end of November of the same year.
A rapid stream of changes and new model numbers followed in this early post-war area, as pre-war parts dried up and new designs were substituted. The naming followed a clear system: the first number represented the chassis/engine iteration, with "1" being the pre-war (17T) design. The second digit was for the bonnet and grille, the third digit for the cab, and the fourth and final digit for the rear body. 1121 thus had mostly pre-war parts, with a post-war design for the cab. The 2225 had post-war chassis and front end designs, with a fourth redesign of the rear bodywork. The grille was a plain, painted pressed steel piece. Some numbers were assigned but never used, such as rear body designs 2 and 3. The 2225 was succeeded by the 2125 at the end of July 1948; this seemingly retrograde step marked the return to the more ornate pre-war 17T grille.
In January 1949 the 3135 took over, followed by the January 1950 3145 model with a slightly different cabin. In August 1950 the Datsun 4146 arrived, introducing the 860 cc Type 10 engine with 15 kW (20 hp; 20 PS). The 4146 also had a bit more chrome trim included, as well as a stronger transmission. The power increase allowed for a somewhat bigger cargo area but top speed only crept up from 67 to 70 km/h (42 to 43 mph).
In 1951 the 5147 appeared, introducing a longer wheelbase of 2,150 mm (84.6 in) rather than the 2,005 mm (78.9 in) chassis which had been used for seventeen years. Most important was the introduction of hydraulic brakes, replacing the original mechanical units. The 5147 was succeeded two years later by the final 6147 model, which received the 25 PS (18 kW; 25 hp) D-10 version of the old sidevalve engine. The extra power output was made possible because of higher quality petrol allowing for higher compression rates. Although somewhat longer and with a bigger engine, the Datsun 6147 remained very similar to the prewar type 15 truck. Payload increased from 500 to 600 kg (1,100 to 1,300 lb) while overall length increased to 3,406 mm (134.1 in). A rare double-cab version, the DU-5, was introduced alongside the 6147. The 6147 was built until the 1955 introduction of the all new 120-series truck.

Common 1990 Nissan D21 problems
The Nissan D21, also known as the Nissan Hardbody, is a compact pickup truck that was produced in the late 20th century. While the D21 was known for its ruggedness and durability, there are several common problems that owners have reported over the years.
One of the most common issues with the Nissan D21 is related to the timing chain tensioner. As the truck accumulates miles, the timing chain tensioner may break, causing a loud noise on startup. This problem can be resolved by replacing the tensioner, and it is not uncommon for D21 owners to experience this issue multiple times as the truck ages.
Another issue that has been reported by D21 owners is related to the brake master cylinder. The brake master cylinder is responsible for providing hydraulic pressure to the brake system, and if it fails, the brakes may not function properly. Replacing the brake master cylinder can be a costly repair, with estimates ranging from $207 to $372.
The Nissan D21 has also been subject to several recalls over the years. The largest recall of the model came in 1995, when cars were invited to dealerships for troubleshooting with five issues. The common problems for this model include lighting (16), equipment (5), seats (3), brakes (1), and doors (1).
The lighting system on the D21 has been a particular area of concern, with multiple recalls related to issues such as faulty headlights and taillights. Equipment-related recalls have included issues with the fuel system, powertrain, and suspension. Seat-related recalls have focused on problems with the seat belts and seat adjustment mechanisms. Brake-related recalls have addressed issues with the brake system, while door-related recalls have focused on problems with the door latches and hinges.
In addition to these common problems, the Nissan D21 has also been known to experience issues with the PCV valve, which can cause the engine to run poorly or stall. Replacing the PCV valve is a relatively simple and inexpensive repair, with estimates ranging from $63 to $76.
Overall, the Nissan D21 is a durable and capable truck that has been popular with owners for its ruggedness and versatility. However, like any vehicle, it is not without its share of common problems and issues. By staying on top of routine maintenance and addressing any issues as they arise, D21 owners can ensure that their trucks continue to provide reliable service for many years to come.
