Nissan K7M 1.6l Engine.

Nissan K7M 1.6l Engine.
Description, Expected Specs & Highlights

Nissan K7M 1.6l Engine is a lightweight, economical, and durable powerplant designed for urban driving and light commercial use.

Frequently found in models like the NP200 1.6L (8V) in the South African market, this engine is typically an inline-4, 8-valve, single overhead cam (SOHC) design built for simplicity and ease of maintenance.

With a likely displacement in the 1.6-litre class (~1,598 cc), the K7 series engines typically deliver power in the region of 60–90 kW and modest torque suitable for daily driving. The Nissan K7M 1.6l Engine version is often marketed as a robust, fuel-efficient replacement engine, supplied fully assembled with ancillary components where possible.

Our units are hand-selected, compression-tested, and verified to ensure no visible cracks or damage to the head or block. These engines are imported from low-mileage, running vehicles and are ready to install — ideal for replacing worn engines, restoring work vehicles, or light commercial swap projects.

Common Weaknesses & Maintenance Notes.

While the K7MF / K7M family is appreciated for its simplicity and durability, here are some known weak points and recommended maintenance practices (based on similar engines) to encourage confidence:

Valve cover gasket & rocker seal leaks: Over time, gasket material can harden and leak oil — replacing these is inexpensive and straightforward.

Ignition coils and spark plugs wear: At higher mileage, misfires or rough running may occur; regular inspection and replacement with OEM parts prevent issues.

Carbon buildup in throttle body or intake: Particularly when driven in stop-and-go traffic, carbon can accumulate in the intake or throttle body. Periodic cleaning helps maintain smooth idling and throttle response.

Cooling system care: Overheating is detrimental. Ensure the radiator, hoses, and thermostat are in good condition. Flushing coolant at regular intervals preserves engine health.

Oil quality & intervals: Use good-quality 5W-30 or equivalent petrol engine oil and change every 8,000–10,000 km (or as recommended). Neglecting oil changes can accelerate wear on cam, lifters, and bearings.

Tensioner / belt health (if belt driven): If the cam is belt-driven (depending on variant), replace timing belts and tensioners periodically to avoid catastrophic failure. (Check your specific K7MF variant’s service manual.)

When properly maintained, many Nissan K7M 1.6l Engine exceed 300,000+ km and deliver reliable service, making them a cost-effective, low-stress choice for regenerative or replacement engine needs.

Every Nissan K7M 1.6l Engine we sell is carefully tested and inspected prior to listing to ensure top quality. This unit has no visible cracks or damage on the head or block and comes hand-picked from a clean, running vehicle in Japan, showing a verified mileage of around 50,000–80,000 miles.
