Fluid temperature regulator includes a unitarily-formed housing having an inlet, outlet, bypass outlet, and plurality of valve chamber openings, in line with respective valve chambers. Valve holders are removably disposed within valve chamber openings to position thermostatic valves within the valve chambers. Each valve holder includes at least one wall having at least one holder outlet opening and holder bypass outlet opening. First and second regulator flowpaths through the regulator are defined through the regulator inlet to either the regulator bypass outlet or regulator outlet depending upon whether the thermostatic valves are disposed in a first or second configuration, respectively.

A monitoring system for monitoring fluid parameters in a lubrication system of an engine may include an input conduit configured to be in fluid communication with the lubrication system at a first location upstream of an oil cooler of the lubrication system. A monitoring device may be in fluid communication with the input conduit. An output conduit may be in fluid communication with the lubrication system at a second location downstream of the oil cooler. The output conduit may include a flow restrictor configured to provide a desired pressure and flow of a fluid to the monitoring device via the input conduit.

A self-cleaning oil filter housing is disclosed. The self-cleaning oil filter housing includes a hollow elongated body. The hollow elongated body has a central axis and a transverse axis perpendicular to the central axis. The self-cleaning oil filter housing includes a first flange provided on an outer surface of the hollow elongated body. The first flange has a first through hole along a first tangential direction. The self-cleaning oil filter housing includes a second flange provided on the outer surface of the hollow elongated body. The second flange has a second through hole along a second tangential direction. An angle between the first tangential direction and the second tangential direction is pre-determined. The self-cleaning oil filter housing includes a rib portion extending between the first flange and the second flange.
