Hi, I'm Ron and I will be helping you today.Stand by for a moment while I prepare your answer.
First, make sure your fans are working right.
next would be to check for a blown head gasket by doing a compression /cylinder leak down test.
Another thing that's rare, but a plugged engine block too can cause that.
Hi, I'm just following up with you to see if you have any more questions.Thanks, Ron
