Your GMC has a very efficient cooling system. A cooling system is essential, as an engine generates large quantities of heat as it operates. Part of the heat generated comes from the combustion, and the rest from hundreds of fast-moving engine components. The radiator removes this heat from your engine. Over time, your radiator can become worn or damaged. These are a few signs that you need to see your GMC dealer for a radiator repair.
Signs You Need a Radiator Repair at Your GMC Dealer
Coolant Leaks
Coolant is a liquid mixture of water and antifreeze. It’s pumped through your engine at high speed and absorbs heat as it moves. The heat is then locked inside the coolant and transported to the radiator. Inside the radiator, the coolant enters the radiator fins. Cool air blows in through the radiator grille, and this airflow over the fins removes the heat.
A coolant leak is usually easy to identify. If coolant leaks out of the cooling system, you’ll see pink, blue, green, or yellow liquid on the ground. Coolant can sometimes leak into your engine. The leaking coolant will leave the exhaust system and generate a thick white cloud. We can trace a coolant leak, and then we’ll repair it.
Damaged Water Pump
As we saw, coolant must be continually pumped through the engine to control the temperature. The water pump is responsible for pumping coolant, and it varies the pumping speed depending on the level of heat in your machine. If the temperature increases, the pump speeds up, and it slows down as the temperature drops.
A water pump can eventually fail. Coolant will be released if this happens, but won’t move through your engine. Your engine will steadily overheat without the flow of coolant, and your temperature gauge will rapidly increase. If this happens, call our service department right away. We’ll examine the pump, and we can install a new one if required.
Loose Hose Clamps
Two thick rubber hoses connect the radiator to the rest of your cooling system. These hoses allow hot coolant to flow into the top of the radiator and cooled coolant to flow out the bottom. Strong clamps are used to securely connect the hoses to the radiator, as the hoses will move in response to the high-speed movement of hot coolant.
Radiator clamps can slowly loosen over time. A loose clamp can cause highly-pressurized coolant to leak out. Air will also be able to enter the cooling system through the gap. This can result in a blockage in the cooling system due to an air bubble. We’ll examine the clamps and tighten them or replace them.
