My 350Z was overheating so I took it to Sun Devil Auto in Sun City West. Sam Malone inspected it. He said I needed a new radiator, hoses, gaskets for a price of $1400.00+ .I went to the Firestone dealer in Surprise on Meeker, he told me to go put antifreeze in and check ot out. I did and no overheating now? Mr. Malone lied to me and I want him fired.
