FAQ - A1No, an overheating engine could mean an issue with your radiator, but there are other pieces of the cooling system that could cause the engine to overheat. It is important to check for coolant leaks or a malfunctioning fan. If you look at the radiator and there is a lot of corrosion or holes there may be a problem with the radiator. Either way it is important to get the whole cooling system checked when your engine overheats.

Signs of Wear & Troubleshooting - S1 B1Vehicle overheating: This is often a sign of a problem with your cooling system, but could be caused by various parts of your vehicles cooling system. It may be because of low or empty coolant level, broken/malfunctioning cooling fans, leaks from broken hoses, or a broken/damaged radiator.
Signs of Wear & Troubleshooting - S1 B2Rust Accumulation: Radiators are constantly exposed to moisture, meaning they can be prone to corrosion. If you check your coolant and it has a brownish tint then you may have excessive corrosion. It is best to have you radiator inspected and flushed to clean out the rust. Using high quality coolant helps prevent corrosion, refer to your owner's manual for proper coolant type.
Signs of Wear & Troubleshooting - S1 B3Radiator Leaks: For various reasons, radiators can develop leaks. Radiators can become damaged in an accident. The end tanks can crack or split and it is important to inspect your radiator for damage often. Damaged radiators should be replaced to help ensure that your vehicle doesn't leak coolant and cause overheat or performance issue.
