{CAUTION: An electric engine cooling fan under the hood can start up even when the engine is not running and can injure you. Keep hands, clothing, and tools away from any underhood electric fan. If the coolant inside the coolant recovery tank is boiling, do not do anything else until it cools down. The vehicle should be parked on a level surface. If your vehicle has the 3.5L V6 engine, the coolant recovery tank is located in the rear of the engine compartment on the passenger's side of the vehicle. If your vehicle has the 5.3L V8 engine, the coolant recovery tank is located in the rear of the engine compartment on the driver's side of the vehicle. See Engine Compartment Overview on page 308. When the engine is cold, the coolant level should be at or above the cold fill line on the coolant recovery tank. To check the coolant level, look for the cold fill line on the side of the coolant recovery tank that faces the engine. If the level is not correct, there may be a leak at the pressure cap or in the radiator hoses, heater hoses, radiator, water pump, or somewhere else in the cooling system. {CAUTION: Heater and radiator hoses, and other engine parts, can be very hot. Do not touch them. If you do, you can be burned. Do not run the engine if there is a leak. If you run the engine, it could lose all coolant. That could cause an engine fire, and you could be burned. Get any leak fixed before you drive the vehicle. 327
