The Bosch intercooler pump on M113k engines is commonly known to fail. This pump is responsible for circulating the coolant through your cooling system. When it fails, the coolant is no longer being pumped through the heat exchanger like it's supposed to, which results in higher than normal temperatures for your engine. Many experience "heat soak" and a large loss of engine power when this happens.
