Your Nissan has different major fluids that enable it to work effectively. Fluids slowly degrade, losing their specialized abilities and potentially causing damage to your vehicle. A fluid check is part of your regular maintenance that involves testing the fluids and replacing them if necessary. As your Nissan dealership, we want to tell you more about some of these fluids and why they’re important.

Some of the Fluids Tested During a Fluid Check
Engine Oil
Top of the fluid list is engine oil. It lubricates numerous engine components, protecting them against friction damage and allowing them to work smoothly. It helps reduce your engine temperature due to its cooling effect as it moves. Finally, it contains additives that prevent rust and break down potential blockages before they form.
Oil thickens as it ages due to the accumulation of dirt and minute debris collected during its travels through the engine. This slows the oil down, turning it from gold to brown or black. Thicker oil is less effective at lubrication, increasing wear and tear on engine components. We drain the old oil, replace the oil filter to ensure the oil flows freely, and then refill the engine with fresh oil.
Coolant
Coolant is a mixture of antifreeze and water and removes engine heat. It’s pumped through the engine, absorbing heat as it moves. The radiator also plays a key role in this process.
Older coolant can thicken due to the accumulation of debris, slowing it down and preventing it from quickly removing heat. This causes the engine temperature to increase, potentially damaging the engine. It will also become corrosive if not regularly replaced. We’ll drain and replace the coolant, allowing your engine to cool correctly again.
Brake Fluid
This fluid provides the hydraulic power necessary to force the braking system to engage. It’s highly pressurized and is forced through the hoses when you hit the brakes. Older brake fluid absorbs water, making it less effective at providing hydraulic power. Replacing the brake fluids fixes this problem.
