How much does it cost to fix a 2018 Dodge Durango is leaking oil?

Common Repairs

The total repair cost will vary based on the condition of your vehicle and the number of repairs needed to fix your symptom. Proper diagnosis will save you money by finding the exact repairs needed to fix your car right the first time.

Oil pans don't wear out or break like other parts, they generally only need to be replaced because of external damage from an accident or an improperly tightened drain plug. The main symptom you will experience is an oil leak underneath the engine of your car. The oil that leaks from a damaged oil pan will range from dark brown to dark black. If the leak is large enough or occurs for long enough the oil level will be low enough to turn the oil pressure or low oil level warning light on.

The engine oil pressure warning light will come on if the engine oil pressure is low, or if the oil pressure sensor is faulty. In either case, engine power may be reduced significantly. The check engine light may also illuminate, and an on-board diagnostic (OBD) trouble code will be stored in the vehicle's computer.

What steps should I take to diagnose the oil leak in my 2018 Dodge Durango?

To effectively diagnose an oil leak in your 2018 Dodge Durango, begin with a systematic approach that prioritizes simpler checks before delving into more complex diagnostics. Start by locating the leak; inspect the ground beneath your vehicle for any visible oil spots, which can help pinpoint the source. Next, examine the oil pan for cracks or damage, as this is a common area for leaks. Ensure that the oil filter is securely installed, as a loose or damaged filter can also lead to oil escaping. Don’t overlook the oil drain plug; if it’s loose, tightening it may resolve the issue. Additionally, inspect the gaskets and seals around the engine, particularly the valve cover and oil pan gaskets, as these can deteriorate over time and cause leaks. The oil pressure sensor is another component to check, as it can sometimes be a source of leakage. Finally, keep an eye on your oil levels; a significant drop can indicate an ongoing leak that needs immediate attention. By following this diagnostic approach, you can efficiently identify the cause of the oil leak and take the necessary steps to fix it.

What are the common causes of oil leaks in a 2018 Dodge Durango?

When diagnosing oil leaks in a 2018 Dodge Durango, it's essential to consider several common problems that could be at play. One of the primary culprits is a worn or damaged oil pan gasket, which can deteriorate over time and lead to significant leaks. Additionally, a faulty or improperly installed oil filter can also result in oil escaping, so checking the filter's condition and installation is crucial. Another frequent issue is the valve cover gasket, which may wear out and allow oil to seep out. It's also important to inspect the oil drain plug, as a loose or damaged plug can be a straightforward source of leaks. Lastly, the rear main seal is another potential leak point that should not be overlooked. By understanding these common causes, DIYers can effectively troubleshoot and address oil leaks, ensuring their Dodge Durango remains in optimal condition. Regular maintenance and timely inspections are key to preventing these issues from escalating.

How urgent is it to address the oil leak in my 2018 Dodge Durango?

Addressing an oil leak in your 2018 Dodge Durango is not just a matter of routine maintenance; it is an urgent issue that requires immediate attention. Oil leaks can significantly reduce the oil levels in your engine, leading to inadequate lubrication of vital components. This lack of lubrication can cause severe wear and tear, ultimately resulting in costly engine damage. Furthermore, neglecting an oil leak can lead to overheating, which poses a serious risk of engine failure and expensive repairs. Additionally, the safety implications cannot be overlooked; leaking oil can drip onto hot engine parts, creating a fire hazard that endangers both the vehicle and its occupants. Therefore, it is crucial to address any signs of an oil leak promptly to safeguard your vehicle's performance and ensure your safety on the road.
