Cummins Radiators Buyer’s Guide:

Cummins Radiator Buying Guide

Want to buy the best radiator for your car? Our buyer’s guide will surely aid you in coming to the best decision.

Following we have discussed a few points to keep in mind while going to buy a radiator for your vehicle.

What Material Am I Looking At?

First things first:

As you know, a radiator will be dealing with cooling off your engines.

Therefore, you need to look for the best material with which it can be made up of.

Usually, Aluminum is what you are looking for.

The fins of aluminum not only let the coolant pass easily but also decreases erosion and increases durability.

The Tubes Should Be Wide:

Looking at it logically, we can easily understand why wider tubes are required to evaluate a radiator. The wider and stronger the tubes are, the more easily a larger quantity of fluid can run through them.

Also, the chances of a radiator breaking down with wider tubes are less.

Therefore, go for a radiator whose tubes are wider.

You Need a Radiator Fan to Cool Things Off:

A fan is an integral part of the radiator. The electric fan saves power and energy, whereas mechanical fans can consume too much energy. Some mechanical fans can consume up to 20 Horsepower.

Can you imagine how much power that is? It is a lot. So, when you are looking for a radiator, check what type of fan it has.

What Size Do I Need?

Another important feature to look for is the size of the radiator. It should fit your car or otherwise, it is of no use to you.

Is the Radiator Compatible With the Rest of the Engine?

One of the most important questions you need to answer before buying a radiator is to see if it is compatible with the rest of the engine.

Buying the best radiator in the market is of no use if it does not sync in with the rest of the engine.

How Much Are You Willing to Pay?

You need to be sure that you are willing to pay the price of the radiator.

Frequently Asked Questions:

Q. Is it possible to replace the radiator on my own?

You can change the radiator on your own only if you have the know-how of the mechanics of a radiator. On the other hand, if you are a layman, it is better advised to seek professional help in changing the radiator.

Q. How can I find a leak in the radiator?

The easiest way is to put it to a pressure test. What you do is that you put pressure on the coolant in the radiator pipe. As a result, if there is some leakage, the coolant will come out swiftly from that side and you will get to know where the radiator is leaking from.

Q. Can a radiator from a 2 wheel drive be used in a 4 wheel drive?

Generally speaking, radiators are very specifically made. A radiator that is made for a 2 wheel drive will not be able to stand the pressure of the 4 wheel drive.

Hence, it is not advisable to use the same radiator for different vehicles.

Q. How often should the radiator fluid be changed?

It should always be changed according to the manufacturer’s manual. If you are not given any specification, it can be changed from anywhere between 24,000 and 36,000 miles, or every 24 to 36 months.

Q. Is a 3-row radiator better than a 2 row one?

After the advent of aluminum radiators, this concept has finished that more rows are better. Now only the product that performs better is the best.

Q. How to clean Cummins Radiator?

It is best to seek professional help while cleaning the radiator. But if you want to do it yourself, it is best to search on YouTube.
