Split Thermostat Hose This thermostat hose gave way after running at the drag strip in Ennis. You can see the huge 2 inch split in the underside of the hose. It's a real pain to get to this hose and shorten/reattach it when all you have is a pair of pliers, a few sockets and a razor blade, and you're doing it in a gas station parking lot at 1am.
