The radiator is a vital part of your car’s cooling system. It takes in hot coolant and uses airflow from the radiator grille to remove the heat and transport the cooled coolant back into the system. If your radiator fails, the hot coolant will cause your engine temperature to rise and your engine can overheat. As your GMC dealer and Buick dealer, these are some of the signs that you need a radiator repair.
Your radiator has two hoses, one which brings hot coolant into the radiator, and the other which takes the cooled coolant back to its reservoir. These hoses are tough, and they are designed to operate under high pressure and at high temperatures. Hoses will wear over time, and they will either develop a leak or collapse and block the flow of coolant.
A coolant leak from the hoses is one of the most common causes of a radiator problem, and one of the easier to solve. We recommend checking the hoses regularly, as we do when we service your vehicle. Replacing a hose is as simple as unclamping the old one and fitting a new one. If one of the hoses collapses, it will block the flow of coolant, and your engine temperature will start to rise.
Your cooling system is a closed one, and coolant should never be found outside the system. Coolant, a mixture of antifreeze and pure water, works to absorb the heat of your engine and transport it to the radiator where the heat is dissipated to the outside air. If your coolant level is low, the pressure in your cooling system will be reduced and the remaining coolant will not work efficiently.
We check your coolant levels when your car is serviced, but we advise checking your coolant especially if you have transported heavy loads. Low coolant can easily cause your engine to overheat, and we advise contacting us if your coolant seems to be consistently below its required level.
If you switch on the heater and it doesn’t blow hot air, this can be a sign that your radiator is failing. Your cooling system uses heat from the hot coolant to warm your cabin. As air passes of the radiator pipes filled with the hot coolant, the air heats up and this air is blown into your cabin when you switch on your heater.
There are several possible causes for a heater problem, including a coolant leak or a thermostat failure. Our technicians will check your engine, and they will find the cause of the problem.
