Curious

see if the fans come on when it gets hot , get the definitions of the codes , what does the exhaust look like ? have someone rev the engine and see if a healthy blast of exhaust comes out the tail pipe to see if the cat. is clogged , , look in the bottom of the oil foll cap what do you see ? over heating for what ever reason can ruin a head gasket and a blown head gasket will cause over heating , you can replace the thermostat and check the condition of the coolant or have a compression test done for a definite answer

The fan does come on what would you consider a healthy blast of exhaust should be? What is the oil foll cap? What exactly would a compression test tell me? I do have a dime size hole on top ofmy over flow for the radiator would that do any damage or cause it to do what it's done? It only has over heated twice the check engine or service engine. Soon was on for about a week and went off, funny thing is the windshield wiper light came on the other day and I went to fill it up it didn't even use a quarter of the bottle before it was full. Could I tighten the cat my self? I'm not very smart when it comes to cars don't know much

look on the bottom of the oil fill cap , scan for codes even if he light ain't on , a compression test will tell you if the head gasket is blown , you can't tighten the catalytic converter
