The heat from combustion and the movement of hundreds of working parts all increase the temperature in your Cadillac’s engine. Your radiator works continuously to keep this temperature under control and prevent the engine from overheating. As with all mechanical parts, your radiator can suffer damage. In Temecula, CA, your friendly Cadillac dealer can provide radiator repair. These are some of the signs you may need to see us soon.
Signs You Need a Radiator Repair at Your Cadillac Dealer in Temecula, CA
Worn Radiator Hoses
Two thick reinforced rubber hoses connect your radiator to your cooling system. These hoses allow hot coolant from the engine to flow into the radiator for cooling, and the coolant that’s already been cooled to flow out of the radiator. These hoses can, however, suffer damage.
As part of your service schedule, we check the radiator hoses for signs of damage. If the hoses have not been checked, they can become less flexible and develop cracks on the outside of the hoses. These cracks can develop into holes, and a hole will result in hot coolant spraying out of the hose and into your engine. We can check your hoses and replace them if they’re damaged.
Broken Thermostat
When your engine temperature rises over 180 F, coolant is released into your engine to reduce the temperature. This coolant, a mix of antifreeze and water, can absorb heat from the engine. The coolant is pumped through to the radiator. In the radiator, the hot coolant is cooled by airflow over the radiator tubes.
The release of coolant is dependent on a small component called the thermostat. The thermostat opens to release the coolant when the engine temperature reaches a preset level. If the thermostat fails, it can jam open or closed. A closed thermostat will prevent the release of coolant regardless of the engine temperature. Without coolant, your engine will rapidly begin to overheat. Our technicians can easily replace a broken thermostat for you.
Damaged Radiator Fan
The hot coolant is pumped into thin tubes in the radiator, and air flowing in through the radiator grille cools the liquid in the tubes. The faster you’re traveling, the faster the airflow and the faster cooling takes place. If your engine is idling, for example, if you’re stuck in gridlock, airflow through the radiator isn’t sufficient to cool the liquid. In this situation, the radiator fan will come on.
A fan is attached behind your radiator, and it activates when there’s reduced airflow through the radiator grille. The fan blows across the tubes, blowing the heat from the coolant out of the radiator. If the fan is damaged, it won’t be able to cool the tubes, and your engine will start to overheat.
If your engine shows signs of overheating, call us ASAP at Paradise Cadillac. Our expert technicians will find and repair the problem.
