At AAMCO Norman, OK , also serving the surrounding area, we know that overheating can cause severe damage to your engine and the transmission.
We also know that the effectiveness of the coolant (also termed anti-freeze) can diminish over time and lose many of its protective properties, even causing your radiator to rust and corrode. The cooling system itself can get clogged with built-up deposits from oil, grease, scale, hose decomposition, and other materials.
Coolant/antifreeze manufacturers recommend changing the coolant fluid once a year, and some service manuals stipulate flushing and refilling the radiator every 24 months, regardless of mileage. Check your car's owner manual, or come to AAMCO Norman, OK , also serving the surrounding area, where we can give you information on the recommended interval for changing the coolant in your vehicle.
Since coolant protects your engine from overheating and from freezing, AAMCO's rule of thumb is to change the fluid every 24 months (at minimum), or if you have any of the following symptoms:
- Your vehicle overheats
- Your coolant or temperature light comes on
- Your temperature gauge reads higher or lower than normal
- Your heater does not work
