Thanks to Mark, our Toyota didn't overheat. I had been filling the coolant overflow container but didn't realize the Radiator was almost bone dry. Mark diagnosed an air pocket, filled me up. He also uncovered a leak in transmission fluid - I was a quart low and had no idea. Either one of these problems could have been quite costly. But he helped avoid that and didn't try to oversell me on addl. work. Rare these days. Would definitely recommend working with Mark if you get the chance.
