We know you have been looking for a simple article that guides you into making your truck radiator replacement simple. You already are aware of what a radiator is and how vital of a component it is for the vehicle since it assists in protecting the engine from overheating.
As the engine is popularly known as the heart of the vehicle, it is essential that the engine is also taken care of. The last thing you want is to have steam billowing out of under your hood while you're driving. Depending on how serious the issue is, it can be either a minor inconvenience or a total catastrophe.
Without beating around the bush, let us give you a basic overview of: -
Truck Radiators vs Car Radiators
Before we dive into the WHYs and HOWs, let’s first learn the answer to one of the most burning questions most vehicle owners have.
There are many similarities between car radiators and truck radiators. Your truck's cooling system works very well in the same way as your car's.
These are the main differences between car and truck radiators. Radiators designed for trucks are designed to handle heavy loads, vibrations, stress, and higher mileage.
Automobiles and trucks use two types of radiators, cross-flow radiators and downflow radiators. There are two coolant tanks (fender to fender) on the side of a cross flow radiator, and the fluid runs horizontally along the front of the vehicle. Fluid runs vertically down the front of the vehicle from tanks at the top and bottom of the down flow radiator.
Low-flow radiators, which pass coolant multiple times through the radiator, and bolt-on radiators, which bolt tanks to a core using gaskets, are two other types of radiators for heavy-duty trucks. Radiators of these types can be cross-flow radiators or downflow radiators.
Factors to Determine before Truck Radiator Replacement
To determine what is the best option for you, use the following checklist.
Other detailed factors to evaluate before making a decision are as follows:
Picking up the right core!
Radiator cores are located between the tanks. Coolant circulates through tubes, and heat is transferred to the air passing through the fins. In a core, rows are the numbers of tubes from one face to the other. In a radiator with three rows, there are three lines of tubes. The more rows you have, the more tubes you have, and the more cooling you get. In other words, how do you choose the right core for you?
Copper Radiator Core
Keep the above points (engine power, vehicle usage, vehicle type, etc.) in mind to explain your decision.
Your engine's horsepower determines how much heat it produces. A properly cooled engine prevents overheating and ensures that your car performs at its peak. When the engine is cooled too much, it will not reach its optimum operating temperature, which will cause decreased fuel efficiency and emissions.
Your cooling needs will probably be drastically different based on whether you drive your truck in the city or if you regularly race at track meets. You'll need an efficient radiator if you want high cooling capacity and minimum weight. In contrast, a city truck or passenger car is likely to fit a stock standard replacement or something similar.

Climate also plays a major role. Australia, for instance, has a hot summer. There are, however, some states that are significantly more affected by humidity or heat than others, such as Queensland or the Northern Territory. Under these conditions, a vehicle's radiator might need to be larger and have more rows to dissipate excess heat.
Generally, a high-performance or heavy-duty vehicle can benefit from 3+ radiator rows. Stock 1-2 is often highly efficient for standard uses, but it can also be incredibly efficient for very strenuous uses.
Other Core Specifications to Keep in Mind
When choosing a radiator, consider other core specifications as well as the number of rows. In vehicles that cannot fit a thicker radiator with more rows, high performance cooling can be achieved by adapting these factors: -
As the coolant flows through tubes, their size and surface are critical. There is a direct relation between the amount of surface contact and the amount of heat dissipation. Wider tube surfaces, for instance, increase the area of contact, which leads to more efficient cooling. In addition to improving cooling performance, more tubes can also be fitted within the same core size to increase cooling efficiency.
In order to maximize heat dissipation, fins are placed between tubes, where the bulk of the heat dissipation occurs. As a result of increased contact between the tube and fin, heat can be transferred more efficiently from the coolant passing through the tubes. A change in FPI (fins per inch) and fin type can adjust heat dissipation.
The core of a device is composed of fins and tubes. In an everyday modern road car, a single row core is common. Some other factors that can increase cooling include FPI, fin type, core and header material as well as tube pitch (distance between tubes), size and surface.
Materials to Consider
It is common for older cars to have copper brass radiators. Radiators made of aluminum started to replace steel ones during the 1970s. Despite its weight, copper brass works well in tough environments such as trucks and highway applications. It can also be disassembled for easier repair.
A new road car is likely to be fitted with a radiator made from aluminum and a fuel tank made of plastic. Typically, they last the entire life of the vehicle, but environmental factors or collision damage can shorten this lifespan. Despite their efficiency and lightness, the cores cannot generally be repaired if they are damaged.
It is common for performance alloys to be custom made to meet specific requirements. Their lightweight, high efficiency, and strict fitment requirements frequently mean they differ from typical radiator dimensions because they are designed to fit restricted engine bays. It is important to ensure that the radiator core fits the vehicle, as some vehicles do not have enough clearance for a thicker core.

On the DRC website there is a find by VIN, Make and Model. Did you submit that? Fast flow has a hose at the top and bottom of the radiator. I would ask for standard stock replacement, matches what came from the factory. What year is your truck, does it have the EGR, DPF...? They have been in business 87 years which is good. I'm skeptical of their Better cooling = Better mpg because the fan runs less. It may overcool at times. Cooling system, emissions, horsepower, ECM.... all programmed to work together. I'm not one for messing with the original design/specs. If the lady is vague that is a warning sign. They should be able to tell you what they have for a stock replacement. And their website should explain low flow, high flow etc.
"The Big Cam IV engines are great to work with, especially the later 88 NTs. The only issue these engines have is their low-flow cooling system. They can easily overheat in demanding situations, particularly in the heat of summer. Peter Sharp, Vice President of Pittsburgh Power, has been working with the Big Cam Cummins for over 30 years and he highly recommends that you revert the low-flow system back to the high-flow system used on all Small Cam and Big Cam I, II and III engines.
