How can I tell if I have oil in my radiator?

When your car is completely cooled down of coarse, simply opening the radiator cap or cap on your coolant reservoir will quickly tell you if you have any oil in your system. Since oil is lighter than water most of the oil in your cooling system will float to the top of your radiator or coolant overflow tank.

Why is the oil pressure warning light still on?

If you have refilled your engine oil with a new one but the light is still on, the culprit could be the engine pressure sensor. The sensor is connected through a circuit from the engine to the dashboard. With time the sensors get filled with dirt and this reduces their ability to detect low oil pressure effectively.

What should I do if my check engine light comes on?

Keep in mind that the fault code that caused the light to turn on in the first place is stored in your car’s onboard computer, and you can retrieve it using a simple Bluetooth-powered device linked to an app to get a precise idea of what exactly is wrong under the hood. Doing this on your own will save you money.

Why do I need to remove oil from my radiator?

What to do if your check engine light is on?

You’ll need to make sure the system is working to pass your next SMOG check. A Toyota dealer or someone else with an ODB-II scan tool can view real time data of the sensors as the engine is running and compare it to Toyota data available in the service manual.

When does the check coolant light illuminate?

In many cases, when the ECT sensor fails, the “check coolant” light will illuminate–if applicable to the specific vehicle–in addition to the MIL. Jody L. Campbell spent over 15 years as both a manager and an under-car specialist in the automotive repair industry.

Why is the Check Engine light on on my Toyota Camry?

A repair shop may tell you the code is P0420, which could mean a new front catalytic converter and O2 sensor. You should clear the code and see if it comes back. Mechanics may suggest replacing the O2 sensors.

One is at the head gasket where oil can leak across the top of the head to the water passages (or into the cylinder or out the edge of the gasket) if the head isn’t properly torqued of perhaps if there is corrosion in the cooling system. Or the gasket could just be failing.
