“This specific Toyota forerunner model had a recall for gasket failure. We had it replaced at appx 74,000 miles done by Toyota as a courtesy recall. This truck currently has very low mileage considering the age of the truck, about 148,000 miles. It recently almost caught fire overheating after another gasket failure. We feel that either the original repair was not properly completed or another faulty gasket was installed. It's amazing that both times the gasket failed at around the same mileage, 75,000. This car has been extremely well maintained and garaged with a single owner.”
