To ensure the longevity of your engine and maintain the validity of your warranty, it is essential to follow these maintenance guidelines. Failure to follow these guidelines may void your warranty.
1. Professional Installation
Mandatory: The engine must be installed by a certified mechanic or at a licensed automotive shop. Proof of professional installation (e.g., an invoice or work order) is required within 30 days of purchase to activate the warranty.
Pre-Installation Inspection: Before installation, the engine must be inspected for any visible defects such as cracks, leaks, or signs of damage. If any defects are found, contact Ovoko immediately before installation proceeds.
2. Recommended Fluids and Lubricants
Use OEM-Specified Fluids: Always use original equipment manufacturer (OEM) recommended oils and coolants.
Engine Oil: Use the correct viscosity as specified in the vehicle’s manual (e.g., 5W-30, 10W-40). Avoid mixing different oil types.
Coolant: Use manufacturer-recommended antifreeze/coolant, ensuring the system is flushed and filled properly.
3. Oil and Filter Changes
Initial Oil Change: Perform the first oil change after 500-1,000 km following the engine installation. This removes any contaminants or particles from the break-in process.
Regular Oil Changes: Continue with regular oil changes every 5,000 to 10,000 km, depending on the engine type and oil used. Always replace the oil filter during each oil change.
Filter Quality: Use only OEM or high-quality oil filters to avoid restricting oil flow, which could lead to engine damage.
4. Coolant System Maintenance
Coolant Flush: Before installing the engine, ensure that the coolant system is flushed and cleaned to remove any debris or old coolant residue.
Check for Leaks: After installation, inspect the engine for any coolant leaks. Repair leaks immediately to prevent engine overheating.
Coolant Replacement: Replace coolant every 2 years or according to the manufacturer’s recommendations.
5. Timing Belt or Chain Replacement
Mandatory Replacement: If the engine includes a timing belt, it must be replaced at the time of installation, even if the belt appears in good condition. If the engine uses a timing chain, ensure it has been inspected and meets the manufacturer’s specifications.
Regular Inspection: Inspect the timing belt or chain during each scheduled service, as failure to maintain the timing mechanism can result in catastrophic engine damage.
6. Regular Inspections and Tune-Ups
General Inspection: Every 10,000 km, inspect the engine for:
Oil Leaks: Around the oil pan, valve cover, and seals.
Coolant Leaks: Around hoses, water pump, and radiator.
Fuel System Leaks: Around injectors and fuel lines.
Tune-Ups: Replace spark plugs, ignition coils, and any faulty sensors at regular intervals according to the vehicle’s maintenance schedule.
7. Engine Cooling and Airflow
Air Filter Maintenance: Replace the engine’s air filter every 15,000 km or sooner if the vehicle is driven in dusty conditions.
Cooling System Inspection: Ensure that the radiator, water pump, and thermostat are in good working condition. Clean the radiator fins and check for clogs or corrosion.
Fan Operation: Ensure that the engine cooling fan operates properly and is set to the correct temperature to avoid overheating.
8. Fuel System Maintenance
Fuel Quality: Use only the recommended fuel type (e.g., unleaded gasoline, diesel) for your engine. Avoid using fuels with more than 10% ethanol content, unless specified by the engine manufacturer.
Fuel Filter Replacement: Replace the fuel filter according to the manufacturer’s schedule or every 30,000 km to avoid fuel system clogs.
9. Regular Maintenance Records
Documentation: Keep a detailed record of all maintenance performed on the engine, including receipts and mechanic invoices. This record will be required if you need to make a warranty claim.
Service Logs: Maintain a log of service intervals, including oil changes, coolant flushes, and timing belt replacements.
10. Warranty Voiding Factors
Modifications: Any modifications to the engine, including performance tuning or the addition of aftermarket parts, may void the warranty.
Negligence: Failing to perform regular maintenance, using incorrect fluids, or ignoring warning signs (e.g., overheating) will void the warranty.
Improper Use: Engines used for racing, off-road driving, or in vehicles that are not street legal are excluded from warranty coverage.
