There are three major maintenance practices you should know to ensure efficiency and performance of your vehicle.
1. Vehicle Health Check: This includes recording mileage, check dashboard lights, check engine oil level, check transmission fluid level, check power steering fluid level, check brake fluid level, check battery health, check windshield water level, check radiator water level and look out for leakages, check brake pads and tire pressure (check for sensors failure). Check for general leakages. This type is also known as preventive maintenance practice
Make sure this is done monthly and anytime you plan going on a long journey.
If you plan to do this yourself you, you will need the following tools. A personal diagnostic scanner (get yours at genuine Auto Solutions Marketplace @ great prices), vehicle maintenance log book (or any book to record your findings or get it free when you buy our mechanic service) piece of cloth. Get understanding of the dashboard codes to be on a safer side.
It is best to get a professional mechanic to do this for you (GAS mechanic services recommended; get professional mobile mechanic services at affordable prices).
2. FLUID MAINTENANCE:
Minor Maintenance (Everyone 3 months OR 3-5K miles): Change engine oil and oil filter, check and clean air filter, check transmission fluid, check battery and cables, check power steering & break fluid, inspect hoses for cracks, Inspect fan belt, check brakes, check radiator water level. In some cases oil change can occur at 10,000 miles depending on the type of engine oil used. For non synthetic oils, it is recommended to change oil every 3,000 miles and 5,000-10,000 miles depending on the type of synthetic oil used (some synthetic oil has annual protection)
Major Maintenance (5-30k miles): Change all oils, fluids and filters(oil, air, transmission, AC), lube chassis, lube steering rod, check and change transfer case fluid, check brakes, check plugs, lubricate suspension, change front/rear differential fluids
3. MECHANICAL MAINTENANCE (Annually OR 10,000-15,000 miles): Change spark plugs, change front and rear brakes, change wiper blades, inspect steering and suspension, lube door and hood hinges, check brakes and wheel bearings, check your oil pump and radiator health
Please make sure you record all your vehicle mechanic services or repairs and the mileage at which these occur. This will help you or any mechanic to keep tract of your vehicle health and serves same purpose just like your medical records.
