I have removed all four retaining nuts and onhooked both lines. Now how do I get the cooler out? There doesn't seem to be any way to remove it from the brackets.

 

That should be it. Are the brackets bent? That usually happens on those oil coolers. the brackets should be level to the ground.

 

So the nuts should face the ground? Mine kind of face the front so the cooler would have to go into the radiater to come off. Should I just pull on the top of the oil cooler to straighten it up? I really appreciate your help. I am hoping that a radiator shop can fix my cooler so I don't have to get a new one.

 

You are correct, the nuts should be facing the ground. Just bend the brackets back so they are level with the ground and out she comes.
