The oil cooler in your vehicle is like a smaller version of the radiator. It's located in front of the engine's cooling system, and it only runs when the engine is at work. Basically, this component is in charge of cooling down the oil that passes through the coils. By doing so, it helps extend the life of the engine oil and of the engine itself. After years of continued use, the cooler will eventually get clogged and start to malfunction. This problem usually occurs because the cooler has small and narrow passageways that can get blocked by the suspended particles in the coolant. And when this happens, simply cleaning or flushing the component may not be enough. You might need to replace your vehicle's old cooler if it's damaged.
Symptoms of a Broken Oil Cooler
There are several signs and symptoms that you can watch out for. Here are some of them:
Having poor engine performance is probably the first thing that you'll notice while you drive. If you have slower acceleration and the engine seems to have difficulty running, check the cooler right away.
Having a distended radiator is a telltale sign of a broken cooler. When this happens, you should also check for broken hoses in your vehicle.
If you see dark or black smoke coming out of the exhaust, check the cooler right away because it might have a leak. The black color of the smoke is caused by leaking engine oil that has reached the combustion chamber.
Like the previous symptom, take note that having oil in the combustion chambers will lead to mismatched explosions in the engine cylinders. This, in turn, will make the engine vibrate.
Benefits of Getting a Replacement Oil Cooler
As mentioned above, merely flushing the cooler may not be enough to remedy the damage. Instead, you need to replace it completely. Here are some of the benefits that you'll gain upon replacement.
- Engine oiling will be improved
- EGR gasses will be cooled more efficiently
- The life of the EGR cooler will be prolonged
- The coolant will not leak or come out of the overflow bottle
- The quality of the oil that runs through the interjectors will be improved
How to Install a New Oil Cooler
Here's a quick guide that will teach you how to replace a damaged cooler. Note that some of the steps may vary depending on your vehicle.
Step 1: Before you begin, remove the old and busted cooler first.
Step 2: After that, find the OEM port holes for the cooler by looking for the line between the oil pump and oil pan.
Step 3: Once you've located them, match the adapters on the oil lines with the holes before attaching the bolts.
Step 4: Next, move the hoses and tubes away from the engine parts that heat up by fastening them.
Step 5: After that, mount the oil cooler in place and connect it to the oil lines before replenishing the engine oil.
