Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hello I will help,
With a leaking head gasket and AC that you need not working I think it is time you moved on to another vehicle. Sell this one for what you can get and put the money toward another one. Have it checked out at a shop before you purchase, if the seller will not allow that then walk away. It will be the best $100 you ever spent on a car. You should be able to get the $100 back when you negotiate the sale using the information you get from the shop.
Please let me know how I can help
