Under the Hood Inspection
For maximum service life of your truck engine, make a thorough under the hood inspection before starting the engine. Look for such items as oil or coolant leaks, loose bolts, loose or worn drive belts and trash build-up. Remove trash build-up and have repairs made as needed.1. Inspect the radiator for leaks and trash build-up.2. Inspect the radiator, oil cooler hoses, heater hoses and PCV hoses for cracks and loose clamps. 3. Inspect the water pump and multiple groove drive belt for cracks, breaks or other damage.4. Inspect the water pump for leaks. The water pump seal is lubricated by coolant in the cooling system. It is normal for a small amount of leakage to occur as the engine cools down and parts contract.5. Inspect the engine for oil leaks, such as front and rear crankshaft seals, crankcase, oil filter and valve cover.6. Inspect the fuel system for leaks, loose fuel line clamps and fittings and loose or worn hoses. If leaking is observed, find the source and correct the leak. If leaking is suspected, check the fluid levels more frequently than the recommended service intervals prescribed in this publication until a leak is found or fixed, or until the suspicion for a leak has been proven to be false.7. Inspect wiring for loose connections and worn or frayed wires.8. Inspect air intake system hoses and elbows for cracks and loose clamps.9. Inspect engine grounding system for good connections and condition.Pre-Start Checks
1. Maintain the crankcase oil level between the ADD and FULL marks on the dipstick. Add oil if necessary.Never use the words themselves to measure the oil level. Wipe all fittings caps and plugs before servicing. Remote mounted or auxiliary filters require additional oil. For information relating to auxiliary filters, refer to your GMC TopKick/Chevrolet Kodiak dealer or the auxiliary filter manufacturer's recommendations.2. Check the coolant level with the engine stopped and cold. Remove the filler cap slowly to relieve pressure.Refer to GMC TopKick/Chevrolet Kodiak Owner's Manual for proper coolant level. To prevent engine damage, never add coolant to an overheated engine. Allow the engine to cool first.
Typical Example3. Observe the air cleaner service indicator (if equipped). Service the air cleaner when the yellow diaphragm enters the red zone or the red piston locks in the visible position.If your truck air cleaner is not equipped with an indicator, your GMC TopKick/Chevrolet Kodiak dealer, who is an authorized Cat 3116 engine dealer can provide one for you.4. Do not fill fuel tank to top. Fuel expands as it gets warm and may overflow. Drain water from the water separator.
