Honda Coolant

Coolant

Coolant is the lifeblood of your vehicle. Coolant is pivotal to keeping your engine operating at a safe temperature. Your Honda’s engine needs clean new fluid in the summer to combat the high temperature and humidity. It is also critical in the winter to keep the fluid from freezing and damaging the engine. While Coolant is critical to your engine the system that contains it is equally important. Coolant is pumped from the radiator that cools it through a series of hoses into the engine and hvac system and then back to the radiator to cool again. But what else is there about the cooling system that needs to be checked and serviced? Listed below is a description of all of you vehicles cooling system components.

Radiator:

A radiator is a type of heat exchanger. It is designed to transfer heat from the hot coolant that flows through it to the air blown through it by the fan. Most modern cars use aluminum radiators. These radiators are made by brazing thin aluminum fins to flattened aluminum tubes. The coolant flows from the inlet to the outlet through many tubes mounted in a parallel arrangement. The fins conduct the heat from the tubes and transfer it to the air flowing through the radiator.

Radiator cap:

A radiator cap is more than a way to open and close the radiator. The radiator cap is actually a pressure release valve, and is usually set to 15psi. As the coolant heats and cools it builds pressure. A properly operating radiator cap releases this excess pressure and coolant back into the overflow tank.

Thermostat

The thermostat’s main job is to allow the engine to heat up quickly, and then to keep the engine at a constant temperature. It does this by regulating the amount of water that goes through the radiator. At low temperatures, the outlet to the radiator is completely blocked — all of the coolant is recirculated back through the engine.
Once the temperature of the coolant rises to between 180 and 195 F, the thermostat starts to open, allowing fluid to flow through the radiator. By the time the coolant reaches 200 to 218 F, the thermostat is open all the way.

Cooling fans:

Most modern vehicles use a series of electric fans to help maintain the temperature of the coolant during different driving conditions. These fans operate independent of each other and turn on and off as the computer in the car commands. While a vehicle is driving the fans aren’t needed as much because the airflow across the radiator does a good job cooling the system. In severely hot temperatures or while sitting idle the fan’s are turned on to help cool the radiator.

Water pump:

The water pump is what circulates the coolant through the engine and thermostat. A properly operating water pump ensures the coolant is circulating the way it needs to be able to properly cool and heat the engine. Most Honda Water pumps are designed to be replaced every 100,000 miles.

We recommend servicing the cooling system annually in the fall to ensure your coolant can withstand the coming temperatures.

A note from Honda about the Importance of using Honda genuine engine coolant:
When you’re driving in extreme temperatures, the last thing you need is engine failure. Whether in extreme heat or cold, Honda Genuine Longlife Blue Antifreeze/Coolant provides long-term corrosion protection to all metal and non-metal parts of your Honda’s cooling system and protects against boil over and freezing. Honda Genuine Longlife Blue Antifreeze/Coolant is the only coolant designed specifically for Honda vehicles. Its pre-mixed formulation is so advanced, no coolant service is required for up to 10 years or 120,000 miles. Use Honda Genuine Longlife Blue Antifreeze/Coolant for optimum long-term engine performance.
