hot_carA car’s engine generates a tremendous amount of heat because of fuel combustion, friction, from the exhaust gases, and so on. Additionally, external temperatures can also increase the temperature of the car and its components. Given the increased use of electronics components in modern cars, the additional heat can lead to failure of critical components and sensors posing a danger to the car and its occupants as well as others on the road.

Rising Temperatures put Pressure on Radiators

In order to avoid these issues, all cars have a cooling system in place that ultimately depends on the radiator to transfer the heat out of the vehicle. Car owners in Texas should be aware of the dangers to their vehicle when external temperatures rise, making it more difficult for the radiator to cool the engine.

In order to maintain the heating and cooling system of your car, both of which use the same coolant, car manufacturers recommend an annual checkup of the system, coolant flush, and coolant change.

One of the most effective materials to enable an efficient transfer of heat is water. However, it can freeze in very cold conditions or reach a high boiling point before it manages to transfer the heat. To overcome these issues, most car coolants have a 50 percent antifreeze component. This helps ensure that the heat is transferred out of the car in an efficient and safe manner. However, over time, the antifreeze degrades and turns corrosive damaging the tube, belts, and other components of the cooling and heating system.

Basic Maintenance

To ensure that is does not happen, manufacturers recommend that the antifreeze or coolant is completely flushed out once a year and new coolant used.

While most manufacturers recommend only a coolant flush and change, it is important to use this opportunity to visually inspect the cooling and heating system for any damage.

Items to Check

A skilled mechanic who has been trained to inspect the heating and cooling system in a car will check the belts for damage, tighten belts that are loose, replace frayed belts; look for rotten, bulging, or brittle hoses and replace them, tighten hose clamps; perform a radiator cap pressure test to ensure that it can withstand the expected pressure; check the thermostat to ensure that the system opens and closes properly; perform a pressure test to identify any external leaks in the coolant passages, hoses, or radiator; perform a test for internal leakage of the combustion gas into the cooling system; and ensure that the cooling fan in the radiator works.

A comprehensive check of the cooling and heating system in a car at least once a year is a poignant way to ensure that it does not fail at crucial moments.

A check of the heating system in the car will comprise not only a check of the coolant but also the hoses that bring heated air into the car. This air should not include exhaust fumes that are poisonous. The mechanic will ensure that there are no leaks into or from the hoses that bring warm air into the car. This will ensure greater fuel efficiency and comfort for the occupants.

Summer Season Car Threats

Automobile associations and manufacturers typically warn motorists of the dangers of overheated engines and cars especially in the summer months. Overheated engine components and sensors can lead to a stalling or even complete stoppage of the car. Additionally, many of the electronic components of the car such as on-board navigators can malfunction, leading to increased chances of being in or causing an accident.

Professional Advice

Just as car owners need to ensure that their vehicle is serviced at regular intervals, they need to top off the coolant in their vehicle once a month. At this time they can perform a visual inspection of the belts and hoses on their own (a flashlight may be required). However, they need to also use a professional mechanic or technician to inspect the heating and cooling system annually. These mechanics will also make use of special testing equipment to help spot any weaknesses in the system such as leaks. They will also recommend the appropriate corrective action that can include replacing worn out belts and hoses or changing the pressure cap on the radiator.

In order to minimize costs, the car owner should ask only a trusted mechanic to check the cooling and heating system since this will eliminate unnecessary recommendations.
