How do I clean a radiator?
The car's radiator is like a magnet, attracting all sorts of debris, including insects and dirt. Lift the hood and you may find the radiator fins clogged with debris. When the radiator is cool, bring out a garden hose with a nozzle attached and hose it down. This may help you troubleshoot cooling problems.
What is the best way to check coolant levels?
Certainly, by not removing the cap from a hot radiator — you may get burned! Instead, check the nearby coolant reservoir (recovery tank). If low, add a 50/50 mix of coolant (also known as antifreeze) and distilled water. You can purchase a pre-mixed solution or create the blend yourself.
How often should I flush a radiator?
Your owner's manual offers the best guidance on car maintenance intervals, including how often to drain it. There are signs, too, that it is time for a flush, including leaks, overheating, regularly needing to add coolant, and a persistent sweet smell of coolant fluid.
When should I replace the radiator?
If all your cleaning and maintenance efforts are to no avail and your car continues to overheat, then it may be time to replace the radiator with a new one from Advance Auto Parts. Even so, rule out other possible problems first, including a stuck thermostat, malfunctioning temperature sensor, a busted radiator fan clutch, or even a failed water pump.
