176 element, install the appropriate element ONLY if using another type of antifreeze. 2. Install the filler cap. 3. Start the engine and inspect for leaks. 4. Check water temperature gauge for proper operating temperature. ALR-TO-AIR AFTERCOOLER SYSTEM 1. Caterpillar discourages the use of winter fronts or other air flow restriction devices mounted in front of radiators with air-to-air aftercooled engines. Air flow restriction can cause higher exhaust temperatures, power loss, excessive fan usage and a reduction in fuel economy. 2. A slight reduction in power or response, or a small increase in exhaust temperature, may indicate a small air leak in the charge air cooler core or piping. 3. An aftercooler hose, gasket or duct failure, or significant system leak will cause a large drop in boost pressure and power. The engine can be operated at this power level long enough to reach a safe stop or repair area. Sustained operation under this condition should be avoided. Inspect Check Inspect all air ducting and gasket connections at each oil change. Constant torque hose clamps should be used to secure the ducting. Tighten these clamps until the spring is at least partially compressed. Check with your OEM manufacturer or the Torque Specifications section of this manual for the appropriate torque specifications. 177 PM LEVEL 2 You must read and understand the warnings and instructions contained in the Safety section of this manual, before performing any operation or maintenance procedures. All PM Level 2 maintenance is to be performed at the intervals specified in the Maintenance Management Schedule for the power rating of the engine being maintained. Before proceeding with PM Level 2 maintenance, perform all PM Level 1 and Daily maintenance requirements.
