[. . . ] Start the engine and let it run until you can feel the upper radiator hose getting hot. By this time the coolant level inside the radiator filler neck may be lower. If the level is lower, add more of the proper mix through the filler neck until the level reaches the base of the filler neck. 8. At any time during this procedure if coolant begins toflow out of the filler neck, reinstall the pressure cap. Be sure the arrows on the pressure cap line up like this. 5-1 7 Cooling System - Diesel Engines When you decide it's safe to lift the hood, here's what you'll see: A. Radiator If the coolant inside the coolant surge tank is boiling, don't do anything else until it cools down. The coolant level should be at or above the COLD mark. 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. If it doesn't, your vehicle needs service. 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. Turn the pressure capslowly to the left no until it first stops. (Don'tpress down while turning the pressure cap. ) If you hear a hiss, wait for that to stop. A hiss means there is still some pressure left. 5-21 2. Then keep turning the cap, but now push down as you turn it. 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.
