My car started overheating and I went to several auto shops that want to charge to much money just to look at the car. I found the problem was the idler pulley and the thermostat. I need help doing these repairs myself being that I'm a female and I don't want to get ripped off by someone. I have done minor work to my car before. I'm having trouble getting to the thermostat and there are no videos online. Please help
