Nissan 1.8L (107 cu in) firing order — diagram & guide

As one of the most common engines that serve as base options for Nissan vehicles, the 1.8-liter four-cylinder has been around for almost a decade. While the production has now seized, it’s still present in many used models and the Nissan 1.8L (107 cu in) firing order seems to be a sort of an issue for some owners.

Many drivers wondered if it was the same as for other four-cylinders that Nissan had produced at that time, which is why our team wanted to help. We’ve therefore created this all-around guide on the 1.8-liter engine’s firing order including its cylinder configuration for easier understanding of how it may help your vehicle run longer.

Nissan 1.8L firing order

Let’s cut straight to the point – the Nissan 1.8L firing order is 1-3-4-2, just as it is for other Nissan four-cylinders of the time like the 1.6-liter engine. However, the 1.8-liter one had a variable valve timing system that controlled the valve opening and closing in a way that enabled the most efficiency of the engine.

Knowing the firing pattern can significantly help with proper maintenance. You can use it to raise the cover of the engine and check the cylinders individually before looking for signs of misfires or worn-off spark plugs.

Also, the firing order can be applied to look for oil leaks and similar issues, which is always a good thing to keep the engine running for a while longer. You just need to know the cylinder positions to do that, and it’s exactly what we’ll explain in the following section.

The 1.8-liter engine by Nissan is a straight-four engine, which means it has four cylinders arranged in a straight line. This makes it easy for you to check the cylinders and you shouldn’t have any issues applying the firing order if you identify the position of each cylinder first.

The first one is located on the passenger’s side of the engine and from there the cylinders 2, 3, and 4 spread in the opposite direction. Once you identify the first cylinder, the next step would be to work your way through the engine by using the firing order.

Nissan 1.8L vehicle applications

One last thing that we have to discuss regarding this engine and its firing order is the list of vehicles that use the engine. So, our team created a full list to show you if the mentioned firing order can be used for your vehicle model:

• Nissan Almera
• Nissan Sunny

The engine was also used in the Nissan Wingroad van and the Bluebird Sylphy compact vehicle sold in Japan.

Our take
