King CabPickup
2.4L I4 (KA24E) · Pickup
The 1992 Nissan King Cab (D21 chassis, sold in North America simply as the 'Nissan Pickup' with an extended cab body) is a compact rear-wheel-drive or part-time 4WD truck built at a time when Nissan still made no-nonsense, bare-bones workhorses. The King Cab designation means it has a small fold-down rear jump seat behind the main bench — useful for the occasional extra passenger or extra gear storage. These trucks earned a strong reputation for durability and are still commonly seen on Wisconsin back roads three decades later. The standard powertrain is a 2.4L inline-four (KA24E) paired with a 5-speed manual or 4-speed automatic. The engine is simple, carbureted in early trim years but fuel-injected from 1990 onward, and responds very well to routine maintenance. A V6 option (3.0L VG30E) was available but far less common. At 30+ years old, virtually every surviving example is a used purchase, and condition varies enormously. In Lake Geneva and the broader upper Midwest, the biggest concern with these trucks is rust — the frame, rockers, and cab corners are known rust magnets after years of road salt exposure. A clean, well-maintained D21 is still a capable light-duty truck and an affordable entry point into the used compact pickup market.

Maintenance schedule
- 1 Every 3,000–5,000 miles Engine oil and filter change
The KA24E tolerates mileage abuse poorly — sludge buildup accelerates timing chain wear. Conventional oil is fine; just change it consistently.
- 2 Every 30,000 miles Spark plugs, distributor cap, and rotor replacement
At 30+ years old, the ignition system is simple but age-prone. Fresh plugs and cap/rotor keep the engine running cleanly and starting reliably in cold weather.
- 3 Every 2 years or 30,000 miles Coolant flush
Aged coolant loses its anti-corrosion additives. Aluminum engine components corrode from the inside out — particularly important in Wisconsin freeze/thaw cycles.
- 4 Every 30,000 miles Fuel filter replacement
Debris from aging fuel tanks can clog the filter. A restricted filter stresses the fuel pump and causes hard starting.
- 5 Every 60,000 miles or as needed Inspect and re-pack front wheel bearings (RWD) or service hubs (4WD)
These are serviceable, non-sealed units. Salt contamination accelerates wear. Catching a worn bearing early prevents wheel-off incidents.
- 6 Annually (fall) Thorough undercarriage rust inspection and treatment
Frame rails, crossmembers, and cab mounts are prone to rust perforation in Wisconsin. Annual inspection with cavity wax or rust inhibitor applied to bare metal extends service life dramatically.
- 7 Every 30,000 miles Manual transmission and differential fluid change
These are relatively small fluid volumes and cheap to service. Neglected gear oil breaks down and causes bearing and gear wear on a truck that may already have high mileage.
- 8 Every 2 years Brake fluid flush
Moisture absorption in brake fluid lowers the boiling point and promotes caliper and wheel cylinder corrosion — a real concern on a salt-belt vehicle this age.
Always defer to the manufacturer's service manual for warranty-mandated intervals.
Cost of ownership
Annual maintenance
$400 – $1,200
Fuel
At roughly 23 MPG combined and current upper Midwest fuel prices, expect around $1,500–$2,200/year for average driving (~12,000 miles). The small 2.4L engine is inherently economical.
Insurance
Liability-only coverage on a 30-year-old truck typically runs $400–$700/year in Wisconsin. Adding comprehensive may not be cost-effective given the vehicle's market value.
This is one of the most affordable vehicles to own on a day-to-day basis. Parts are cheap and widely available, labor is minimal for the simple mechanicals, and fuel costs are low. The wildcard is rust remediation — a structural rust repair can easily exceed the truck's market value. Budget carefully for undercarriage work if buying a Wisconsin example.
Seasonal care
Lake Geneva, WI Winter
- Test the battery before first hard freeze — a 30-year-old truck may be on its second or third battery; cold cranking amps drop sharply below 20°F and the KA24E needs a strong crank to fire in sub-zero temps.
- Switch to a 5W-30 or 0W-30 full synthetic if using conventional oil — thinner cold-weather viscosity allows faster cold starts and quicker oil circulation to the timing chain.
- Fill washer fluid reservoir with a -20°F or colder rated formula — the underhood temperatures on these trucks allow the reservoir and lines to freeze if summer fluid wasn't swapped out.
- Inspect wiper blades and replace with winter-style blades — standard blades can ice up and skip across the windshield in Wisconsin freezing rain.
- Rinse the undercarriage every 1–2 weeks during heavy salting periods — the frame and cab mounts trap road salt and accelerate rust. Even a simple pressure wash at a coin-op car wash helps.
- Check 4WD engagement before winter arrives — vacuum lines and front axle actuators dry out and crack over summer; better to discover a stuck hub in October than on a snowy road in January.
Summer
- Check tire pressure at every fill-up — ambient temperature swings between Wisconsin seasons can shift pressure by 4–6 PSI, and these older trucks often have narrower tires with less margin for underinflation.
- Inspect the rubber coolant hoses and thermostat — heat soak in a 30-year-old engine bay softens old rubber; a blown hose on a hot day can cause quick overheating in the simple cooling system.
- Service the A/C system if equipped — R-12 refrigerant was factory spec; most of these have been converted to R-134a by now, but if it hasn't blown cold in years, have the system inspected before summer heat arrives.
- Check the battery again — extreme heat degrades battery plates just as much as extreme cold, and a marginal battery that survived winter may fail in July.
Comparable vehicles
1992 Toyota
Pickup (Xtracab)
Direct rival in the compact extended-cab segment. Similar simplicity and durability reputation; arguably slightly more rust-resistant on body panels, but frames rust equally badly in the Midwest. Parts are plentiful.
No catalog match
1992 Ford
Ranger SuperCab
Same era, same mission. The 2.3L four is slightly less powerful but equally simple. More common in the region, meaning even cheaper parts. Body rust is comparable on salt-belt examples.
1992 Chevrolet
S-10 Extended Cab
Chevy's entry in the compact truck class. The 2.5L four is gutless but durable; the 4.3L V6 option is more capable. Parts availability is excellent. Frame rust is the same concern throughout this class.
1992 Mazda
B2600i Extended Cab
Mechanically near-identical to the Nissan in philosophy — simple carbureted or injected four-cylinder, body-on-frame, part-time 4WD available. Less common, so parts can be harder to source locally.

Red flags
- Any flex or twist in the frame visible when one wheel is lifted — indicates a compromised or cracked frame rail.
- Excessive rust bubbling along the full length of the rockers or beneath the cab — usually indicates the floor and cab mounts are also gone.
- Check engine light with no explanation from the seller — the KA24E's ECU is simple but fault codes on a 30-year-old truck deserve investigation.
- Fresh undercoating sprayed over the frame — a common trick to hide active rust from buyers; probe beneath it if possible.
- Evidence of a rolled or wrecked bed — bent frame rails near the rear hitch are a sign of a hard impact that may have tweaked the chassis.
What to inspect
- Frame rails — probe with a screwdriver; if it punches through, walk away. This is the single most important inspection point on any D21 in Wisconsin.
- Cab mounts and body mounts — these rot out and allow the cab to shift on the frame, causing misaligned doors and structural weakness.
- Floor pans — lift the floor mats and check for rust-through, especially under the driver's feet and behind the seat.
- Rocker panels and cab corners — common rust areas; surface rust is manageable, full perforation means significant body work.
- Engine oil condition — pull the dipstick and look for sludge or milky oil. Sludge means infrequent oil changes; milky oil means a head gasket issue.
- Timing chain rattle on cold start — a chattering noise that goes away after warm-up means the chain is stretched and guides are worn. Budget $500–$900 to address it.
- 4WD engagement (on 4WD models) — test both 4-Hi and 4-Lo engagement on a safe surface. Vacuum leaks, cracked hoses, or a failed front axle actuator are common and should be negotiating points.
