...steering fluids for my 97 Toyota Camry? My toyota dealer told me I need to change my car battery:118 +tax,transmission fluid:185+tax,coolant:150+tax and power steering fluid:125+tax as soon as possible after checking my car when I had gone for the oil change. Then I got my battery tested from walmart and they told me my battery was absolutely fine. After that I have started thinking that may be the dealer was just trying to make money by fooling me. So my question is are there any test I can do it myself before paying so much of money for the maintenance. Is he over charging me for the above costs he told me
