How to Buy an Intercooler
An intercooler is a component used in vehicles with turbo or superchargers. It cools the pressurized-hot air entering the engine from the turbo, thereby preventing the engine from premature wear and detonation. An intercooler is so called because it is usually placed in between turbos in a multiple-turbo system. The intercooler is called an aftercooler when it is placed at the end of the turbo cycle, between the turbo and the engine but oftentimes, the term intercooler refers to any of the aforementioned configurations. This buyer's guide explains the need, types and various locations of intercoolers in a turbocharged engine system. We make it is easy at BuyAutoParts.com to find the correct replacement intercooler for your vehicle.
Purpose of an Intercooler
The intercoolers serve the purpose of reducing the temperature of the compressed air flowing out of the turbocharger or supercharger. The turbochargers are used to push dense air into the engine to increase its horsepower. During the process of compression, the turbo naturally generates a lot of heat. This heat, when allowed to enter the engine, can damage it and result in its untimely failure. Another severe problem caused due to the heat in the engine is detonation. An intercooler is employed in between the turbo and the engine to remove this heat and allow the engine to deliver an optimal efficiency. Intercoolers are available in different sizes and configurations depending on the requirement of the engine.
Kinds of Intercoolers Air-to-air Intercoolers Air-to-air intercoolers use a series of tubes which have fins inside them. The compressed air, when passed through the tubes, transfers the heat to the tubes and the fins. The heat from the fins is then absorbed by the ambient air, thereby cooling the compressed air. Air-to-air coolers are the most common types of intercoolers employed in automobiles. These intercoolers have a simple structure and are lighter than air-to-liquid intercoolers. Air-to-liquid Intercoolers Air-to-liquid intercoolers use water or a water-solvent mixture to reduce the temperature of the hot air. Cool water is passed through intercooler system that removes the heat from the hot air. These intercoolers are smaller than air-to-air intercoolers and are therefore employed in automobiles where space is a major constraint. |
Locations of Intercoolers Intercoolers are mounted to the engine in various ways, depending on the vehicle's requirement and configuration. Front-mounted Intercoolers: These intercoolers are mounted to the front of the engine, under the radiator. This location is the most commonly used for intercoolers. . The front mounted coolers allows for a large amount of ambient air to pass over their chambers, resulting in better cooling. Top-mounted Intercoolers: Here, the intercoolers are mounted to the top of the engine. They reduce the turbo lag as they are located closer to the engine. These intercoolers receive less external air and are hence considered less efficient than front-mounted intercoolers. Side-mounted Intercoolers: These intercoolers are also mounted to the front of the engine, but on the sides of the vehicle (in the front of the wheels). These intercoolers are smaller compared to top-mounted and front-mounted intercoolers. They are less efficient than front-mounted coolers, as they fail to block the air from traveling to the radiator. |
Causes and Symptoms of Faulty Intercoolers
Some of the common symptoms of a defective intercooler include decreased engine efficiency and engine detonation. Due to detonation, combustion process may leave unburnt fuel residue. This can emit a strong odor of gasoline. Otherwise, detonation also causes a pinging or knocking noise.

Maintenance Routine for Intercoolers A periodic inspection of the intercooler can prevent costly repairs for it in the future.

BuyAutoParts.com stocks a wide range of intercooler kits for every make and model. Buying an intercooler kit will give you a large discount. BuyAutoParts.com also stocks Intercooler Pipe Kits. |
Frequently Asked Questions |
Can I take the intercooler off my vehicle and put it into another automobile? |
Definitely not. Intercoolers have minor modifications depending on the year, make and model of your vehicle. Besides that, there are air and water based intercoolers and they are also fixed in different positions. |
Can I install the intercooler hoses myself? |
Changing the intercooler hoses is a pretty simple process and can be done easily on your own. Make sure that you refer to your owner's manual for the location of intercoolers and the precautionary measures for safe installation. |
