How Often Should You Have Your Radiator Serviced
Radiator service for your car will depend on a lot of factors. The cooling components of your car are a sealed system and only require periodic maintenance for proper operation. Engine coolant or anti-freeze concentration is vital to the components of the cooling system and is a factor worthy of consideration. A radiator flush may not be necessary for new model cars (not at least after a couple of years) but old model cars would have to undergo flushing and radiator cleaning as the accumulation of rust and debris may be detrimental to the performance of the engine cooling system. Service would also depend on the condition of your radiator. The presence of leaks and cracked hoses should be consulted with a mechanic or service center at the soonest possible time.
Radiator Care and Maintenance
Ask any qualified mechanic and the answer will be the same: the right amount and concentration of coolant or anti freeze inside your radiator is vital for proper engine performance. The radiator will benefit from proper flushing as it is susceptible to rust and other harmful elements.
With the engine cold, pop open the hood and open the radiator cap. Do not open the cap if the engine is hot as the pressurized contents will burst and may cause painful burns or scalds. Upon removal of the radiator cap, check for rust and accumulated dirt on the cap and surrounding metal parts. If the cap and surrounding parts are clean, this would mean that the radiator is in good condition. Flushing is recommended if excess rust and dirt is present. This will help remove debris and harmful contaminants that may lead to engine overheating.
Remember that the radiator is a vital component for proper engine cooling and performance. Service is recommended at least every year but have the system checked when leaks and rust are evident on the radiator and other parts of the cooling system.
