Put the interior heaters to full blast, try get some of the heat away for the engine bay, the fan on my car doesn't work so when im in traffic I just set the heaters to full and it keeps the engine bay cool enough
If the car was reported as stolen that's a cat c or d write of and when you went to insure it the insurance company would of picked up on the fact it's been written off and would of mentioned it to you as stolen or written off cars are more expensive to insure
