Cooling System When you decide it is safe to lift the hood, this is what you see: {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 surge tank is boiling, do not do anything else until it cools down. The vehicle should be parked on a level surface. The coolant level should be at or above the FULL COLD mark on the coolant surge tank. If it is not, you may have a leak at the pressure cap or in the radiator hoses, heater hoses, radiator, water pump, or somewhere else in the cooling system. 3.5L V6 Engine shown, 2.4L L4, 3.6L V6 and 3.9L V6 Engines similar A.
