What is an Oil in Coolant Reservoir?
Oil in coolant reservoir is an indication of a serious issue with your engine that needs immediate attention. It could indicate a blown head gasket, a cracked cylinder head, or an engine block.
Here’s how you can fix the problem:
- Step 1: Identify the source of the problem. Check for signs of coolant in the oil, power loss, or excess smoke from the tailpipe. If you detect any of these symptoms, it’s best to take your car to a certified mechanic.
- Step 2: Once the source of the problem is identified, drain the coolant and dispose of it safely. Refill the coolant with a fresh supply and run the engine for a few minutes to circulate the coolant.
- Step 3: Flush the coolant system to remove any contamination, including oil, rust or dirt particles.
- Step 4: Replace the oil and oil filter with a fresh supply to prevent further contamination of the coolant system.
It is important to address oil in coolant reservoir as soon as possible, as it could lead to more severe engine damage or malfunctioning.

Causes of Oil in Coolant Reservoir
Oil in your coolant reservoir can be caused by several factors that can range from minor issues to serious engine problems. Here are the main causes of oil in coolant reservoir and how to fix them:
- Engine Oil Cooler Failure: The engine oil cooler can crack or develop a leak, allowing engine oil to mix with coolant. The fix is to replace the damaged oil cooler.
- Cylinder Head Gasket Failure: A damaged cylinder head gasket can cause oil to seep into the coolant passages. Replacing the faulty gasket is necessary to avoid further damage to the engine.
- Cracked Engine Block: A cracked engine block can cause oil to contaminate the coolant. Replacing the engine block might be necessary to fix the problem.
- Transmission Fluid Cooler Failure: If the transmission fluid cooler inside the radiator is damaged, it can cause the transmission fluid to mix with the coolant. To fix the issue, the transmission cooler needs replacement.
In conclusion, fixing oil in the coolant reservoir depends on the underlying cause. It’s important to have a professional diagnose the issue and conduct the repair to avoid further damages to the engine.
Symptoms of Oil in Coolant Reservoir
When you see oil in your coolant reservoir, it may be an early indication of bigger engine problems. To fix it, you should look out for these symptoms:
- White smoke or steam coming from the exhaust pipe.
- The engine overheats frequently.
- The coolant changes color and appears milky or creamy.
- The engine oil changes texture, appears thinner, foamy, and lighter in color.
If your vehicle is exhibiting any of these symptoms, take it to a professional mechanic to check for issues like a blown head gasket, a faulty engine oil cooler, or transmission cooler. Ignoring this problem can lead to a complete engine breakdown.
Pro tip: Regular maintenance checks can help detect such issues at the earliest and save you from huge repair costs in the long run.
Diagnosing Oil in Coolant Reservoir
Noticing oil in the coolant reservoir of your vehicle is a sign of a serious problem, and it can be caused by a number of reasons such as a blown head gasket or a cracked engine block.
