Tips to Keep Your GMC Radiator in Top Condition
Engine failure is commonly caused by an overheating vehicle. This is the reason why your vehicle 's cooling system should never be taken for granted. You should definitely practice preventive radiator maintenance in order to ensure that your engine is performing at optimum levels. Alas, most drivers don 't think about their cooling system or radiator at all until a puddle of green antifreeze forms on their driveway or steam starts billowing from under their hood while they 're driving to work. At that point, you 'll have to take your car to your dealership for repairs with a certified technician. Prevent this from happening by observing the proper maintenance procedures every time.
Use the correct antifreeze or coolant mixture with water.
Many motorists put straight tap water unto their ailing radiators when the car overheats. This isn 't a sound practice. Although many filling stations offer water hoses along with tire air, it 's important to remember that water alone should only be used to cool down your radiator during emergencies. It 's a temporary fix at most. Water isn 't an effective coolant with nothing mixed with it. What 's more, during winter, it can cause your engine to freeze (which is just as damaging as overheating). As a rule of thumb, you should have a 50/50 mix of water and antifreeze on your GMC vehicle to keep the water from freezing in cold weather while still cooling your radiator down.
Keep the radiator full at all times.
Your radiator should stay filled. If it 's leaking and couldn 't get filled, it should be thusly repaired or replaced (maybe the leaks are from the radiator itself or perhaps it 's from any of the hoses connected to it). As a rule of thumb to ensure that your radiator is full, the fluid level should be visible when the cap is removed. From time to time, small leaks can happen and remain undetected all the while. Therefore, it 's only prudent to check your radiator in a periodic manner when your GMC has cooled down. Also, to reiterate a previously made point, you should use a 50/50 mixture of water and antifreeze to top your radiator off whenever it 's in need of fluid.
Have the radiator flushed periodically.
Periodic flush of the radiator is in the best interest of your vehicle 's continued operation the same way periodic checkups to your doctor or periodic meetings with your dentist is necessary for your own healthiness. A qualified automotive specialist should flush your radiator from time to time. He should drain and refill the cooling system with a fresh batch of coolant and water. Keep in mind that there 's no set time interval for these flushes since it depends on your type, model, and year of GMC automobile.
Know when to inspect and flush your radiator.
With that said, for most vehicles, you should flush your radiator every two years or every 30,000 miles, whichever milestone comes first. If you 're using "long-life" antifreeze instead, your flushing can be done every 4 years or 50,000 miles instead, whichever comes first. If your antifreeze comes out as cloudy instead of clear, it might be recommended for you to flush your radiator down regardless. Ditto if your car is running hotter than normal (especially if it 's an old car with a lot of mileage on it). In closing, an ounce of prevention is always better than a pound of cure.
