Car Engine Cooling System

Your car’s cooling system consists of four major parts, which are the radiator, water pump, thermostat and your coolant.


Your vehicle’s radiator is a series of channels where coolant is cooled. Since hot fluids enter, and cold fluids leave a radiator, it is important you never open a hot radiator cap. Your radiator cap holds in a high level of pressure and opening it could cause serious injuries such as burns to your hands and face. Your radiator should be checked occasionally, and depending on the make of your car and the number of kilometers, we can inform you if a radiator flush is necessary. Furthermore, hoses leading in and out of the radiator get brittle with time and these should be replaced or monitored for leaks.

Water Pump

The water pump moves the coolant from the radiator and through the engine, where the coolant is returned back to the radiator. Early signs of a water pump failure are spots of coolant in your parking spot, or a strong coolant odor when you drive.


The thermostat decides when coolant should be run through your engine. When you first warm up your car on a cold January morning, coolant obviously does not need to run through your engine as your car is not running at its ideal temperature. A faulty thermostat may cause your engine to meltdown if it decides to not send coolant to your engine, which is why we suggest checking it on occasion.


Your car’s coolant is a mix of water and ethylene glycol. Ethylene Glycol is what makes your coolant an antifreeze as it stops the water in your car from freezing in cold temperatures. Ethylene Glycol also lubricates the moving parts it may come in contact with, such as the water pump. Coolant gets extremely hot in your car’s engine, and as such, coolant typically has a high boiling point, such as 135 degrees Celsius.


Car air conditioning troubleshooting

In the hot and humid summers of Canada, a car’s air conditioning is essential. Nobody wants sweat stains on their work clothes, as well, driving without an air conditioner can bring on nausea and migraines. If you are planning a long drive, such as a family vacation, you’ll want to come into Hogans Auto Repair Services to ensure you can travel in comfort and style.

Several warning signs your car’s air conditioner may be faulty are that your air conditioning is blowing hot air, or the smell of antifreeze coming from your car’s vents. In order to fix these problems, Hogans Auto Repair Services will examine your compressor, condenser and evaporator which are three components of your air conditioner that work in unison to circulate your vehicle’s refrigerant.

Air Conditioning Compressor

The compressor is the heart of your vehicle’s air conditioning system. What the compressor does is pressurize your car’s refrigerant so it will cool the air.

AC Condenser

Your vehicle’s AC condenser operates like a tiny radiator. It takes hot air, and cools it so it becomes a liquid.

Your Car’s Evaporator

Your car’s evaporator takes the cold air that passes through the condenser and vaporizes it by way of absorbed heat. Here it loops back to the start of the cycle where it is cooled once again in the condenser.
