A strict maintenance routine keeps the HiAce profitable. Engine oil should be changed every 5,000–7,000 km depending on engine condition and road environment. Air and fuel filters need regular replacement to avoid injector strain. Brake pads, bushings, and shocks wear faster on rough Kenyan roads and must be inspected frequently. Cooling systems should never be ignored—overheating destroys engines. Investing in preventive servicing is far cheaper than repairs. A well-maintained HiAce easily runs over 600,000 km with minimal breakdowns, ensuring long-term returns for the owner.
