Similar to how a vehicle's radiator functions to cool the engine, an engine oil cooler serves to maintain the engine oil at the optimal operating temperature. By doing so, it effectively prolongs the lifespan of the engine's moving components and reduces the likelihood of expensive engine repairs being required.
In a typical vehicle, coolant circulates through the main radiator to prevent the engine from overheating. On the other hand, an oil cooler acts as a dedicated radiator solely for the engine oil. It is important to note that the oil cooler's role is distinct from that of the cooling system, which is responsible for regulating the engine's temperature. Engine oil coolers vary in size but are generally smaller in comparison to the main radiator, ensuring efficient oil cooling without compromising the engine's overall performance.
How an Oil Cooler Works
Achieving and maintaining the optimal operating temperature for engine oil is paramount for the longevity and performance of your vehicle's engine. Ideally, the engine oil should operate within the temperature range of 180 to 210 degrees Fahrenheit. Deviating from this range can have detrimental effects on the oil's viscosity and pressure, potentially leading to severe engine damage and costly repairs.
The oil cooler plays a vital role in dissipating heat as it circulates out of the engine, through the cooler, and back into the oil pan, ensuring a consistent flow. Some oil coolers are equipped with a thermostat to regulate the cooling process, closing when the oil is rapidly heated and opening as necessary to maintain the correct oil temperature.
Types of Engine Oil Coolers
Engine oil coolers are available in two primary types: oil-to-water and oil-to-air. Each type functions by circulating the oil through a heat exchanger element to either dissipate or extract heat in order to regulate the oil temperature effectively. As the names imply, the oil-to-air cooler utilises ambient air to cool the oil as it passes over the cooler's fins, resembling a miniature radiator. Some models integrate a thermostatically controlled module bypass valve to redirect cooled oil back into the engine without passing through the cooler until the oil temperature rises.
When selecting the appropriate type of oil cooler for your vehicle, it is essential to consider various factors such as the prevailing climate conditions, the specific make and model of your vehicle, its towing and hauling capacity, as well as your individual driving habits. These considerations will help you determine whether an oil-to-air or oil-to-water cooler is the most suitable choice for your needs.
In the case of adding an aftermarket oil cooler to your vehicle, it is probable that you will opt for an oil-to-air cooler. When paired with a thermostatically controlled valve, this configuration is known for its reliability in maintaining optimal oil temperatures over extended periods. Conversely, an oil-to-water cooler may be more beneficial in heavy-duty applications, such as in large trucks. However, it is important to note that should an oil-to-water cooler develop a leak, there is a risk of coolant and oil mixing, potentially resulting in significant engine issues.
Choosing an Aftermarket Engine Oil Cooler
Oil coolers are available in a variety of sizes, ranging from 10 to 30 rows, and are offered in either tube-and-fin or plate configurations. When selecting the appropriate size of an oil cooler, it is crucial to consider several factors:
- The oil capacity of the system
- The power output of the engine
- The amount of airflow and the available space for the oil cooler
- The size of the radiator
It is recommended to opt for a larger oil cooler that can comfortably fit within the engine compartment while ensuring sufficient airflow. It is also essential to leave space for a thermostat if the system does not already have one installed.
Oil coolers are designed in one-, two-, or triple-pass configurations, indicating the number of times the oil will circulate through the cooler before returning to the vehicle's oil pan. The more passes the oil makes, the more heat will be dissipated, thereby enhancing the cooling efficiency of the oil cooler. Choose the pass design based on the cooling requirements of your engine and the operating conditions it will encounter.
Installing an Oil Cooler
When it comes to the installation of an oil cooler, individuals with a good level of mechanical aptitude may find that they are able to carry out the installation process independently. To begin, it is important to carefully follow the instructions provided with the kit to ensure a successful installation.
One of the key steps involves installing the oil lines that are included in the kit. This process typically entails removing the existing engine oil filter and then attaching the fluid hoses to and from the cooler. It is crucial to pay close attention to the layout of the oil lines to minimise the length and number of bends. By siting the oil cooler as close as possible to the oil filter while still allowing for adequate airflow, you can optimise the efficiency of the cooling system.
Throughout the installation process, it is highly recommended to double and triple-check each step and every connection to prevent the occurrence of leaks. This meticulous approach can help to ensure that the oil cooler functions effectively and without any issues. Additionally, it is advisable to acquire a set of flare nut or line wrenches specifically designed for removing and tightening the hose fittings. These tools can facilitate the installation process and help to achieve a secure and leak-free connection between the oil lines and the cooler.
When it comes to adding oil cooler lines, following these two best practices can make a significant difference in the efficiency and performance of your vehicle:
- Utilise a Specific Sandwich Plate: It is crucial to select a sandwich plate that is tailored to your vehicle's motor. This information is typically included in your oil cooler kit, ensuring that the components are compatible and optimised for your particular application.
- Incorporate a Filter Relocation Kit: Opting for a filter relocation kit with an adapter that matches the original filter location on the engine block can enhance the overall effectiveness of the oil cooler system. This method offers a more efficient approach compared to directly running lines from the oil filter. By routing the lines to the oil cooler first, then to the filter, and back to the engine block, you can establish a smoother and more streamlined oil flow process.
For optimal performance, consider installing the oil cooler at the front of the vehicle, positioned between the radiator and the grille. This strategic placement ensures maximum airflow, enhancing the cooling efficiency of the oil. If feasible, situate the oil cooler close to the existing oil filter to facilitate a more cohesive and seamless operation within the engine system.
Oil Cooler Maintenance
An OEM engine oil cooler is designed to have a lifespan that matches that of the vehicle. On the other hand, universal or performance aftermarket oil coolers are expected to last around 50,000 miles or up to 10 years with minimal issues. To ensure the longevity of your oil cooler and engine, it is crucial to maintain a regular schedule of oil and filter changes. This simple practice can significantly extend the life of your oil cooler.
Regular inspections are essential to detect any potential issues with the oil cooler or oil lines. Look out for leaks, cracks, or any signs of wear caused by factors such as rust, vibration, or general wear and tear over time. It is advisable to inspect the area where your vehicle is parked for any indications of oil or fluid leaks, which could be a sign of a problem with the oil cooler.
There are certain warning signs that may indicate a need for oil cooler repair, including engine or transmission overheating and oil temperature readings higher than normal. If your vehicle is primarily used for daily commuting with occasional road trips, an engine oil cooler may not be necessary. However, if you engage in high-performance driving on tracks or regularly transport heavy loads in hot conditions, installing an engine oil cooler could be a beneficial addition to your vehicle.
