Abstract: A viscous clutch head may be replaced by selecting a viscous clutch head and a mount adapter. The viscous clutch head and the mount adapter may be selected from a group of universal modular fan drives and from a group of mount adapters. The mount adapter of a threaded type or a flange and bolt type may be selected. Depending on the viscous clutch head to be replaced, a fan adapter and/or a pilot adapter may also be selected from a group of fan adapters and from a group of pilot adapters. Accordingly, a range of models of viscous fan clutch systems may be replaced by using a limited number of parts. These parts may be stored on a tool cart. As different models of viscous fan clutch systems may be replaced using a limited number of parts, the in-stock inventory of replacement parts may be reduced.

Abstract: A thermostatic bypass valve has an intentional flow resistance through a bypass passageway when fluid is at a normal operating temperature. This flow resistance, of between 10 and 20 psi at a flow rate of 10 liters per minute, is achieved by limiting a radial clearance within the bypass passageway to less than 1.0 mm. The flow rate through the bypass passageway is at least half of the flow resistance of the cooler. This bypass flow resistance is beneficial because it limits the flow rate of lubrication fluid during bypass, reducing the parasitic losses of the gearbox.

Abstract: A transmission oil cooler transfers heat between Automatic Transmission Fluid (ATF) and engine coolant. During initial vehicle warm-up, heat is transferred from the engine coolant to the ATF, assisting the transmission warm-up. A priority valve may limit the flow of coolant to the transmission oil cooler until the coolant temperature is sufficient to ensure adequate cabin heating performance. After both the engine and transmission have reached normal operating temperatures, heat is transferred from the ATF to the engine coolant. An auxiliary radiator pre-cools the engine coolant before it enters transmission oil cooler. This increases the cooling of the ATF and avoids coolant temperature increase during aggressive maneuvers. When the ATF temperature is below a threshold, a coolant control valve diverts coolant around the auxiliary radiator.
