Nissan Altima Complete Engines

The Nissan Altima is a midsize car that has been in production and for sale since 1992. Nissan has used a number of different motors to power the car over the years. By replacing your complete engine with a new model, you may be able to hang on to your Altima a lot longer.

When should your Nissan Altima’s complete engine be replaced?

Replacing the complete engine on your Nissan Altima can be postponed for a while by replacing specific parts and keeping up with general maintenance. Here are some common signs that will let you know the engine is near the end of its life.

  • Smoke coming from the exhaust: This may be a sign of a cracked block or other internal damage. Blue smoke indicates oil burning. White smoke often means your cooling system has a leak, and black smoke means too much fuel is being consumed.
  • Knocking: This may mean worn-out bearings.
  • Metal shavings in your oil: This is a sign that your Nissan Altima parts are suffering from serious wear and damage.
  • Smoke from under the hood: This may mean melted parts or blown gaskets from operating and too high of a temperature.

What engine types does the Nissan Altima use?

Nissan has used a number of different ones in the Altima over the years. Between 1992 and 2001, a 2.4-L I4 was used. From 2002 to 2006, they used a 2.5-L I4 or a 3.5-L V-6. From 2007 to 2013, the same sizes were used but with some improvements in efficiency and horsepower. From 2013 on, they have used I4 engines in 1.6-L, 2.0-L, or 2.5-L versions. Altimas with 3.5-L V-6 engines are available for those looking for more power.

How long should a Nissan Altima engine last?

Your Nissan Altima engine should last for around 200,000 miles or more. If you get an engine replacement for the vehicle, you should be able to enjoy your Altima for many more years.

How do you break in Nissan Altima engines after replacement?

Most of the breaking in is now an automatic process done in the factory. This is true of Nissan OEM parts and most other manufacturers. After installing a new engine for your Nissan Altima, there are a few things you should go over before running it normally.

  • Check all of the parts for a tight fit. Look out for any leaks.
  • Use a priming tool or a pre-luber to make sure your Nissan is well-oiled before starting.
  • Fresh motors may have trapped air in your car's coolant system. This can lead to fluctuations in the temperature-gauge readings. Make a mixture of half coolant and half water and fill the motor 30 minutes prior to starting. This can avoid some of the air problems.
