0.66L K6A Petrol - 4WD

Engage the 4WD system on a loose surface or gravel. Listen closely for any binding, clicking, or whining sounds during slow, tight turns, as the transfer cases can show signs of age on high-mileage imports.
While driving, pay attention to the gear changes. If the shifting feels notchy or difficult, it is common to consider that the clutch may be nearing the end of its lifespan or the shifter bushings have worn down.
Check this by operating the heater and air conditioning during your drive. K6A-powered Kei trucks can sometimes develop issues with the heater core or blend doors, which are tricky to access in the cab-over configuration.
With the engine running, inspect the coolant expansion tank and oil filler cap. Look for milky residue which can sometimes be an indicator of a failing head gasket, a known occasional point of interest for these hardworking engines.
Major service usually recommended: timing chain tensioner check, cooling system flush, and replacement of all gearbox/diff oils.
Consider a full inspection of the suspension bushings and steering rack components as New Zealand road conditions can accelerate wear on these light vehicles.
Often the threshold where auxiliary belts, alternator brushes, and the water pump might require preventative replacement to ensure reliability.
Check the engine oil levels every few weeks; these high-revving 660cc engines perform best with clean, high-quality synthetic oil.
Inspect the underside for rust regularly, especially if you live near the coast, as body protection is vital for the longevity of these chassis.
Keep a close eye on your cooling system; ensure the coolant is fresh and free of debris to prevent the engine from running hot.
Ensure the tire pressures are set to the manufacturer's recommendation for the specific load you are carrying, as this significantly impacts handling.
Clean the air filter regularly, as the small engine intake is prone to collecting dust if you are using the truck for farm or site work.
Estimated repair costs if issues arise
If the clutch starts slipping or feels heavy, you might eventually need to budget for a replacement. This job involves removing the transmission, so it is a good time to check the rear main seal as well.
While the K6A engine is quite reliable, if you notice a rattling sound at start-up, it is common to consider replacing the timing chain components to keep the engine running smoothly for the long haul.
After years of hauling loads, the suspension may begin to feel tired or 'bouncy.' If this happens, budget for a set of shocks and fresh rubber bushings to restore that crisp Kei-truck handling.
