- Observed the engine coolant temperature gauge and found the engine coolant temperature exceeded allowable specifications. With the scan tool connected to monitor live data, found the engine coolant temperature was above specified operating temperature. Performed a visual inspection of the engine cooling system and found the engine coolant recovery reservoir was empty. After engine cool down removed the cap from the coolant recovery reservoir, topped up the coolant recovery reservoir and installed an engine cooling system pressure tester. Applied pressure to the reservoir and found the reservoir leaked engine coolant. These test results verified the engine coolant recovery reservoir was faulty.
- REMOVE ALL NECESSARY COMPONENTS. REMOVE AND REPLACE COOLANT RESERVOIR RECOVERY TANK. ASSEMBLE TOGETHER AND MAKE ALL NECESSARY ADJUSTMENTS. PRESSURE TEST SYSTEM FOR LEAK, CHECK THERMOSTAT AND HEATER OPERATION. CHECK ALL HOSES AND BELTS. DRAIN AND FLUSH SYSTEM AND ADD ANTI-FREEZE COOLANT.
