Nissan Frontier Radiator Upgrade

A radiator upgrade can be necessary for several reasons. Perhaps your original radiator was damaged in an accident or became eroded over time. Or maybe you’re simply looking for an improved cooling system to keep your engine running at its best. Whatever the reason, upgrading your Nissan Frontier’s radiator can help keep your vehicle running smoothly.

When it comes time to choose a new radiator for your truck, there are many different options available on the market today. So how do you know which one is right for you? Here are some factors to consider when choosing a new radiator:

Tube Size And Row Quantity

Several things to consider when purchasing a radiator, such as tube size and row quantity. The tube size will determine the amount of heat that can be transferred from the radiator, while the row quantity will determine how much surface area the radiator has for heat transfer.

As a general rule, the larger the tube size, the better the heat transfer, and the most common tube sizes are 1″, 1.5″, and 2″.

The row quantity will also affect the heat transfer but to a lesser extent. More rows will mean more surface area for heat transfer and a higher price tag. The most common row quantities are 2, 3, and 4.

When choosing a radiator, it is essential to consider both the tube size and the row quantity to ensure that you get the best possible heat transfer for your money.

Core Size

Radiators are used in various applications to transfer heat from one medium to another. The core size of a radiator is an essential factor in determining its efficiency and performance.

The core size is directly related to the radiator’s surface area, which determines how much heat can be transferred. The larger the core size, the more efficient the radiator will be.


There are two types of materials that radiators are made so far: copper-brass and aluminum radiator. The copper-brass radiator is an old classic type radiator that people have used for a long time.

An aluminum radiator will typically cool better than a copper brass radiator, and due to aluminum’s higher thermal conductivity, it allows a better heat transfer.

Additionally, aluminum is much lighter than copper brass, making it easier to install and transport. Finally, aluminum radiators have a longer lifespan than copper brass radiators, making them a more cost-effective option in the long run.

How Do I Know What Kind of Radiator I Need?

It’s challenging and confusing when it comes to choosing the best radiator for your Nissan Frontier or your vehicle because there’re many choices. We would advise you to go with the OEM radiator because it lasts a long time.

In contrast, a non-branded aftermarket aluminum radiator core can be leaked anytime in under two years since it’s lighter. And an OEM radiator can dissipate heat better.

Moreover, for the best performance of the radiator, you need to pay attention to the right fan shroud and the fan.

There are available OEM radiators on the market for your Frontier; the best if you go with Griffin radiator or Mishimoto.

Radiator Upgrade Process for Nissan Frontier

Here is a step-by-step guide on how to upgrade your Nissan Frontier’s radiator:

  1. First, ensure safety because the radiator has an electrical connection. Therefore, disconnect the battery terminals.
  2. It’s essential to inspect the rest of your coolant system before replacing the whole radiator. Check the radiator cap, belts, and hoses for leaks or damage. You’ll also need to check the fan clutch and engine thermostat. It’s also important to ensure the rest of your coolant system is in good working order.
  3. Begin by draining the old coolant from your truck’s cooling system, which you can do by opening the drain plug at the bottom of the radiator. Be sure to catch all old coolants in a container, as it can be hazardous if it comes into contact with skin or eyes.
  4. After draining the coolant, you need to disconnect the radiator. For disconnecting, you must disconnect the following elements: mounting bolts, cooling fan, shroud, reservoir hose, upper and lower radiator hose, engine oil lines, and all parts connected to the radiator.
    But, you must remember that all bolts, hoses, and connectors are organized because you need to reinstall them reversely.
  5. After completing the last step, remove the old radiator from the vehicle.
  6. Now it’s time to install your new radiator! Slide it between the upper and lower brackets, ensuring that all hoses and fittings are correctly aligned. Then reattach the brackets and tighten them down snugly using an Allen wrench or socket set.
  7. Finally, refill your cooling system with fresh coolant and enjoy improved performance from your Nissan Frontier!

Frequently Asked Questions (FAQs)

Can you upgrade the stock radiator on Nissan Frontier?

You can upgrade 2-rows stock standard aluminum for your Nissan Frontier truck. However, if you have a high horsepower vehicle or one that is used for performance or off-roading, then 3-4 rows are the best option. It will give you extra protection and help keep your truck in good condition.

What is the best radiator upgrade for Nissan Frontier?

Well, the old copper-brass radiator can be weight compared to aluminum, but it transfers heat better than aluminum. Moreover, it can be rusted and sludgy within a few years.
On the contrary, the aluminum radiator is lightweight and can not be eroded or dirty for less than a few years.
You must consider several more factors, such as core size, tube size, and row number because these affect the radiator’s performance.
Therefore, we suggest using an aluminum OEM radiator to keep your Frontier safer and cool in different conditions.
