When your radiator starts to fail your vehicle's cooling system will struggle to keep engine temperatures at a reasonable level. If you notice your vehicle’s temperature gauge reading unreasonably high, it is important to seek help quickly.
Radiator setups run the coolant through a series of interconnected tubes to remove heat from the fluid. As the coolant passes through the radiator, heat sinks help bring the temperatures back down to acceptable levels.
The fan will also turn on and attempt to cool down the fluid temperatures even more right before the coolant flows back through the engine. This process happens constantly to keep your engine from overheating.
As the radiator ages, the coolant passageways may clog up with mineral deposits, blocking the flow of the fluid through the system. If this happens, your cooling system will build up way too much pressure which can damage the hoses, water pump, and thermostat.
If you notice the temperature gauge on your dash reading too high, you should go to a technician to have your radiator and cooling system checked for faults.
Technicians will start by checking the radiator for cold spots, verifying that the system flows well and then they will inspect the engine bay for leaks. Technicians can also test the overall temperature and pressure in the coolant system to confirm that your engine is running hot.
Technicians approach the radiator repair process by thoroughly identifying the problem parts before suggesting component replacements or other services.
If your radiator has a blockage, it may be necessary to have that part replaced with a new one to rectify the problem. Technicians can perform a full coolant flush to attempt to knock the blockage loose before moving ahead with the replacement services.
After performing the cooling system service, technicians will test drive your vehicle to make sure it maintains the proper operating temperature. If the temps or pressure rating rises too high even after switching out the radiator.
Technicians will retest other parts in the system to identify the problem. With cooling system problems, it's common to see more than one part contributing to the lack of flow or pressure buildup.
Upon detecting a problem with your cooling system, you can visit your local Meineke Car Care Center to have your car inspected and repaired. Acting on this problem promptly will help protect your engine from costly damage.
