I had the thermostats replaced. The service was great. A little disappointed that after picking up my truck I got a message to add coolant. When I got home to check the coolant reservoir it was nearly empty. I would have thought that when replacing the thermostats that coolant would have been topped off. I had topped off the coolant about a week prior so I knew it was close to full when I left it. Other than that I was very pleased with the service.
