FLUID SPILLAGE CONTAINMENT Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the machine. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids. Refer to "TOOLS AND SHOP PRODUCT GUIDE, NENG2500", for tools and supplies suitable to collect and contain fluids in Caterpillar machines. Dispose fluids according to local regulations and mandates. The installation of the water temperature regulator is the same for both water temperature regulator housings. For simplicity, the installation of only one water temperature regulator is shown. Ensure all gasket material is removed and all mating surfaces are free of dirt, oil and grease. Replace any damaged or worn gaskets or O-ring seals with a new part if necessary. 1. Install O-ring seal (24) on water temperature regulator (23).
If the water temperature regulator is installed incorrectly, the engine will over heat.
