The Dodge Cummins is a high performance engine that uses an intercooler to improve its efficiency. The intercooler is a device that cools the air charge before it enters the engine, allowing the engine to produce more power. This helps to increase the efficiency of the engine and to improve the performance of the vehicle. The intercooler can also help to reduce the emissions from the engine, and it can help to improve fuel economy.

The intercooler is located between the air filter and the throttle body, and it uses a network of tubes and fins to cool the air charge. The intercooler is an essential component of the Dodge Cummins, and it helps to make the engine one of the most powerful and efficient engines on the market. As a result, the Dodge Cummins is able to deliver exceptional power and fuel economy, so you’ll want to service the intercooler when needed to keep your engine running as designed.

Reasons the Intercooler Fails in a Dodge Cummins

There are several reasons why the intercooler may fail in a Dodge Cummins. One of the most common causes is a build-up of oil and grease on the intercooler fins. This can happen if the engine is not serviced regularly, or if the wrong type of oil is used.

Another common cause of failure is a build-up of debris, such as leaves and twigs, in the fins of the intercooler. This can restrict airflow and cause the unit to overheat.

A potential cause of failure is a leak in the intercooler core. This can allow coolant to escape, resulting in reduced cooling capacity.

Another common cause of failure is a cracked or damaged intercooler core. This can be caused by excessive heat, improper installation, or collision damage. If the intercooler is not functioning properly, it can lead to decreased performance, increased fuel consumption, and increased emissions. In some cases, it may also cause engine damage.

In some rare cases, an intercooler may also fail due to a manufacturing defect. If you suspect that your Dodge Cummins’ intercooler is failing, it is important to have it inspected by a qualified technician as soon as possible.

4 Signs that the Intercooler is Failing

Since the intercooler is responsible for cooling the hot air that comes from the turbocharger, if it’s not working properly, it can lead to a whole host of problems. So how can you tell if your Dodge Cummins’ intercooler is failing? Here are four main signs to watch out for:

  • Increased engine temperature: If the intercooler is not working properly, the engine will run hotter than normal. This can be checked by using an EcuFlash tool to read the engine temperature sensor data.
  • Reduced engine power: A failing intercooler will cause the engine to lose power. This can be noticed when accelerating or climbing hills.
  • Increased turbocharger lag: If the intercooler is not able to cool the hot air from the turbocharger properly, there will be a noticeable delay in turbocharger response.
  • Black smoke from the exhaust: This is a symptom of increased engine temperature and reduced engine power. If you notice black smoke coming from your Dodge Cummins’ exhaust, it’s a good indication that the intercooler is failing and needs to be replaced.

If you notice any of these four signs, it’s important to bring your Dodge Cummins to our qualified mechanic as soon as possible so we can diagnose and fix the problem. Ignoring a failing intercooler can lead to bigger problems down the road, so it’s best to nip it in the bud early on.
