You can have a couple of things going on. One is that the oil cooler is restricted and causing the oil to get to hot. When this happens the engine will debate and show an overheat condition on the coolant gauge. Next is you can have a bad t-stat. The t-stat there are two in this system. If one is sticking closed you can have this issue as well.

You want a excellent 5 star answer & I would like to be rated the same for providing it. Consider I don't know your skill level & I can't see, smell, hear, or touch the vehicle. It may take a few back and forth replies. Try your best to respond with good detail so I can do the same. A rating is required. Your rating me, what I type. I am not an employee of this website, nor have control over the fees or the time it took to get a response. If you rate negative or not at all you still paid, but I get nothing. I want you pleased with me and my efforts, so let me know if your experience here has come up short.
