Does a New Car Come with Engine Oil and Coolant?

New cars do come with engine oil and coolant, and they are filled to the standard level with sufficient quantities. This is because the vehicle needs to undergo a series of subsequent tests, and without these fluids properly added, the follow-up processes cannot proceed. The method for replacing coolant is as follows: Before completely replacing the coolant, conduct a thorough inspection to check for any signs of leakage or cracks in the pipes, with special attention to the five-way water pipe. The coolant flows through this pipe and is then distributed to different parts of the car to perform its functions. If there is any coolant leakage in this section, replace the water pipe or resecure the connection as needed. Drain the old coolant, then flush the fluid channels with clean water. Add clean water to the coolant reservoir, then continuously inject water into the reservoir so it circulates through the engine cooling system. Let the engine idle for 3 to 5 minutes to allow the water to circulate. Initially, the water flowing out of the reservoir may have a faint pink tint. Continue adding clean water until the outflowing water runs clear. Note: Remember to remove the heater hose and drain the water from the heater core. After draining for about an hour, add the new coolant through the radiator hose. Then, pour another container of coolant into the coolant reservoir until it is nearly full. Start the engine and let it run for about 10 minutes. During this time, the coolant level will drop slightly as air is purged from the cooling system. Top up the coolant again until it reaches the "MAXT" mark on the reservoir.
I just bought a new car and was excited to check under the hood during pickup. Of course, a new car comes with engine oil and coolant pre-filled at the factory before delivery! Engine oil is used to lubricate internal engine components, reducing friction and wear; coolant circulates in the cooling system to prevent engine overheating or freezing in winter. As a car owner, I pay special attention to these fluid levels during the break-in period—for example, checking the dipstick and coolant reservoir monthly. During the first maintenance service for a new car, a comprehensive fluid inspection is recommended to ensure freshness. Neglecting this could lead to engine damage, so I strictly follow scheduled replacements, usually once a year or as per the manual’s reminders. Regular maintenance keeps a new car running longer and safer.
