Coolant light and check engine light still on

Hi,

It could very well be a sensor. Here is what I suggest: Since the check engine light is on, chances are there are diagnostic trouble codes stored in the computer. I would have the computer scanned to determine the issue. Here is a video showing how it's done:

Now, I realize most people don't own scanners, but most parts stores will do it free of charge. If you have it done, let me know what code is found and I'll walk you through checking things and replacing anything that needs to be replaced. You'll save a lot. LOL

Let me know what you find. Also, feel free to let me know if you have other questions.

Take care,

Joe

Hello,

Are you talking about the coolant temperature sensor or the coolant level sensor?

If you have a faulty coolant temperature sensor it can illuminate the light saying the engine is too hot.
If you have a faulty coolant level sensor, then it will say the coolant is low.

Since the vehicle runs as usual and you do not have any issues with it. Then it is likely the sensor that is bad.

As for the engine light you will have to scan it get the codes. If you do not have a scanner you can take it to your local auto parts store and they will scan it for you. The code can help diagnose the issue that you might have. If you find out the codes, just let me know what they are.

Please let me know of any questions.

Thank you.

Hi,

I assume this is a 5.0L. If it has the 5.8, let me know.

The CHT is located in the rear of the right-hand cylinder head. I attached a pic below which shows its location.

Let me know if this helps or if you have other questions.

Take care,

Joe
