Hi,

It sounds like the thermostat is sticking open. In this case, it should be replaced.

Here is a link that shows in general how it's done:

If you look below, I attached the directions specific to this vehicle. Take a look through them and let me know if you have questions.

Let me know how things turn out for you.

Take care,
