What Vehicle Parts Are At Risk in the Summer Heat?


America’s roads are always busy, but the summer months are particularly hectic. As millions of Americans head off for their annual summer vacation, you can expect long traffic jams and frustrated drivers.

Modern cars may be mechanically advanced, but they are still susceptible to heat, and the summer sun can be particularly hazardous for certain parts of your car. Allow our skilled service technicians to equip you with information pertinent to your warm weather journeys.

Hoses and Belts

Though it may seem rather obvious, it is very important to keep the engine cool when driving in the summer heat. Hoses help pump coolant to and from the engine while belts enable the fan to run effectively and continually cool your car’s engine.  In extreme heat, however, hoses can crack and belts can snap. You can check the hoses and belts yourself by looking for visual signs of wear or damage. If you are unsure, schedule an appointment with our service department before you set out on a summer road trip.

Cooling system

Modern cars have very effective cooling systems, which can counter relatively high extremes of temperature, but they have their limits. Aside from problems with hoses and belts, low levels of coolant, a leak in the radiator or a missing radiator cap can spell disaster if you are driving in hot weather.


Your car’s tires are vulnerable throughout the year, however, under-inflated, over-inflated or worn tires can be particularly dangerous during the summer. Tire pressure changes as the temperature increases. If the tire is under-inflated, it can bulge outward and put pressure on the sidewalls of the tire. If this continues, the tire can eventually burst. If the tire is overinflated, you are also at greater risk of hydroplaning in the event of a rain shower. Contact our tire center team to avoid potential road hazards.

Oil filter

The car you drive relies heavily on oil, as this substance allows car parts to run efficiently. Heavy driving during the summer puts additional pressure on the oil, and on the oil filters in your car. Aim to change your oil filters as often as the owner’s manual recommends, and certainly get them checked before you head off on a summer expedition.

Whether you are staying local this summer or driving hundreds of miles, we encourage you to contact us soon to protect your car from the rigor of summer heat.
