Claim:
1. A power system, comprising: an engine comprising a block and a head mounted thereto, the engine being lubricated by a lube oil; a first heat transfer circuit coupled to the engine and comprising a first heat exchanger, the first heat exchanger being configured to cool a first circuit fluid that cools the block and the head, the first heat transfer circuit further comprising a first thermostat and a first bypass passage, and when the first thermostat is in a standard position, the first circuit fluid circulates through the first heat exchanger, and when the first thermostat is in a bypass position, the first circuit fluid bypasses the first heat exchanger; and a second heat transfer circuit coupled to the engine and comprising a second heat exchanger and a lube oil cooler fluidly coupled thereto, the second heat exchanger being configured to cool a second circuit fluid that cools the lube oil cooler, and the lube oil cooler being configured to cool the lube oil, the second heat transfer circuit further comprising a second thermostat and a second bypass passage, and when the second thermostat is in a standard position, the second circuit fluid circulates through the second heat exchanger, and when the second thermostat is in a bypass position, the second circuit fluid bypasses the heat exchanger.
