Simple maintenance can help keep things cool on the road this summer. Your vehicle, and passengers, will thank you.
The hot weather is one of the most eagerly anticipated parts of the summer season if you're a human being. If you're a vehicle, the heat means additional strain on vital components during towing, hauling and long family trips.


Poorly maintained parts tend to show themselves when vehicles are pushed to extremes. As such, sweltering summer day is a fantastic time for overheating, driveline failure or engine damage, if your cooling system isn't performing properly. Any of the above will leave you stranded on the roadside with a car full of sweaty, irritated and cranky family members. Fortunately, readying your cooling system for warm-weather travelling is a relatively quick and painless endeavor.

In addition to keeping your engine running at its ideal operating temperature, your cooling system may play a part in keeping other components, like your transmission, from overheating as well. Your cooling system works by circulating coolant throughout the engine to absorb and remove the tremendous heat it generates while running.

Over time, the effectiveness of the coolant diminishes, and a coolant change is required. This occurs in varying intervals for different vehicles, or on an 'as-needed' basis as advised by your mechanic. Forget when your coolant was changed last? It's probably overdue.

A proper cooling system check should include a look at coolant level and effectiveness, the thermostat, and the water-pump belt, if applicable. The radiator and associated hoses and lines should be inspected as well, and a visual check for leaks is also important.

If your ride is dripping green fluid and you're planning a road trip anyways, you're asking for trouble. Overheating can quickly lead to engine failure and permanent, catastrophic damage. Cooling system repairs tend to be considerably more affordable than an engine replacement.

A periodic radiator flush is also advisable to remove harmful sludge from within the cooling system. Sludge may accumulate within the radiator and hoses over time, reducing effectiveness and component life. Put another way, a coolant flush ensures everything is functioning properly, from the inside out.

Thankfully, your cooling system isn't a tremendously complicated animal-- and reliable operation is mainly a function of keeping on top of the maintenance it occasionally requires.
