[. . . ] If it isn't, you may have a leak in the radiator hoses, heater hoses, radiator, water pump 1 or somewhere else in the cooling system. 5-18 NOTICE: Engine damage from running your engine without coolant isn't covered by your warranty. If there seems to be no leak, startthe engine again. See the fanspeed if increases when idle speed is doubled by pushing the accelerator pedal down. Turn off the engine. How to Add Coolant to the Coolant Surge Tank NOTICE: The diesel engine has a specific coolant fill procedure. Failure to follow this procedure could cause your engine to overheat and be severely damaged. If you haven't found aproblem yet, but the coolant level isn't the COLD at mark, add a 50/50 mixture of clean water(preferably distilled) and a proper antifreeze at the coolant surge but be sure the cooling system, tank, including the coolant surge tank pressure cap, is cool before do it. (See you "Engine Coolant" in the Index for more information about the proper coolant mix. ) 5-19 5-20 NOTICE: In cold weather, water can freeze and crack the engine, radiator, heater core and other parts. You can remove the coolant surge tank pressure cap when the cooling system, includingthe coolant surgetank pressure capand upper radiator hose, is longer hot. (Don'tpress down while turning the pressure cap. ) If you hear a hiss, wait for that to stop. After the engine cools, open the air bleed valve on the thermostat housing. 4. Add coolant until you see a steady stream of coolant coming from the bleed valve. Rinse or wipe the spilled coolant from the engine and compartment. 7. Then fill the coolant surge tank with the proper mix, up to the COLD mark. 8. With the coolant surge tank pressure cap off, start the engine and let it run until you can feel the upper radiator hose getting hot. Watch out for the engine fan(s). By this time, the coolant level inside the coolant surge tank may be lower. If the level is lower, add more of the proper mix to the coolant surge tank until the level reaches the COLD mark. 5-23 9. Be sure the arrows on the pressure cap line up like this. h Engine Fan Noise Your vehicle has a clutched engine cooling fan. When the clutch is engaged, the fan spins faster to provide more air tocool the engine. In most every day driving conditionsthe fan is spinning slowerand the clutch is not fully engaged. Under heavy vehicle loading, trailer towing and/or high outside temperatures, the fan speed increases as the clutch more fully engages. This is normal and should not be mistaken as the transmission slipping or making extra shifts. It is merely the cooling system functioning properly. The fan will slow down when additional cooling is not required and the clutch partially disengages. You may also hear this fan noise when you start the engine. It will go away as the fan clutchpartially disengages. I f a Tire Goes Flat It's unusual for a tire to "blow out" while you're driving, especially if you maintain your tires properly. If air goes out of a tire, it's much more likely to leak out slowly.
