1. Adhere to Nissan’s Maintenance Schedule

Your owner’s manual for your Nissan has a maintenance schedule that is tailored to your vehicle’s engine. It contains intervals for oil change, filter change, timing belt inspection, and more.

Pro tips:

Change engine oil at 3,000 to 5,000 miles (or by synthetic oil schedule).
Change engine air filter at 15,000 to 30,000 miles.
Inspect spark plugs at 30,000 miles and replace if needed.
Inspect coolant levels and drain radiator every 60,000 miles.

Why it is necessary:
Be mindful of the factory schedule to prevent premature wear and to keep your engine in top shape.

2. Use the Proper Engine Oil and Fluids

Some Nissan engines require specific viscosities and oil types. The incorrect oil will impede performance and induce long-term wear.

Engine	Recommended Oil	Capacity
QR25DE	5W-30 Synthetic	4.8 quarts
VQ35DE	5W-30 Synthetic	5.1 quarts
VK56DE	0W-20 Synthetic	6.9 quarts
VR38DETT	0W-40 Synthetic	5.2 quarts

Pro Tip:
Use only API-approved oils from reputable manufacturers and change oil while always installing a new oil filter.

3. Inspect the Cooling System

Your cooling system keeps your engine from overheating. Even a minor clog in your radiator will impede performance.

Maintenance includes:

Radiator hose and clamp check.
Flush coolants 2–3 times a year.
Thermostat and radiator cap inspection for wear.

Symptoms of cooling issue:

Engine temperature is higher than normal.
Steam coming from the hood.
Leaks or white buildup on the coolant.

4. Look at the Timing Chain/Belt

Nissans employ a timing chain or belt to coordinate engine components. Chains are longer-lasting but will eventually need periodic checks.

QR25DE and VQ35DE have timing chains.
Timing belts need to be replaced 60,000–100,000 miles.

A busted timing belt or chain can cause catastrophic engine failure. If your engine has broken down this far, perhaps it’s time to purchase a new replacement engine—and we can help.

5. Pay Attention to Warning Signs

Early warning can salvage your engine when it is not too late. Some early symptoms are:

Check Engine Light (CEL) on
Knocking or ticking noises
Rough idling or stalling
Poor fuel economy
Heavy exhaust smoke

Do not ignore these warning signs. Fixing a little problem is cheaper than replacing an entire engine—though if you do have to, we have affordable Nissan engine replacement.

6. Don’t Overload or Drive Aggressively

While Nissan engines are powerful enough to accomplish the task, aggressive driving with no maintenance will result in pre-mature wear.

Avoid:

Rough acceleration and braking
Overloading without proper support
Long high RPMs or redlining

Take proper care of your engine by driving gently, especially during adverse weather or road conditions.

7. Keep It Clean

Engines run best when they are free from grime, dirt, and oil residue. A clean engine is also less difficult to detect leaks and problems.

How to keep your engine clean:

Use degreaser on cool surfaces.
Avoid using water on electrical components.
Clean with microfiber cloths.

Regular cleaning also provides resale value if you ever sell your Nissan or have to replace your engine.

8. Use Genuine Nissan Parts

Alright, so after-market parts might be tempting, but authentic Nissan engine parts are designed to ensure optimal compatibility and performance.

That is why when we sell our engines again, we ensure that they are:

OEM (Original Equipment Manufacturer)
Quality tested and performance-tested
Supported by warranties (in most cases)

When Should You Replace Your Nissan Engine?

There are certain situations where repairs simply aren’t feasible. These are definitive indicators that you must replace:

Knocking or seized engine
Blown head gasket or cracked block
Low compression in multiple cylinders
High oil consumption
Continual overheating

With all of these scenarios, we provide new, genuine Nissan engines for replacement, direct to your mechanic or your doorstep.
