Coolant & Other Fluids
It takes almost as many fluids and chemicals to maintain your automobile as it takes to keep your household. From air conditioning, brake fluids, gear/hydraulic fluids, grease, power-steering fluids, to radiator coolant and transmission fluids, we’ve got you covered.
Coolants are essential to keeping your car happy in this ever-warm, ever-challenging desert climate. Your car operates in a wide variety of temperatures, from well below freezing to well over 100 F (38 C). So whatever fluid is used to cool the engine has to have a very low freezing point, a high boiling point, and it has to have the capacity to hold a lot of heat.
Water is one of the most effective fluids for holding heat, but water freezes at too high a temperature to be used in car engines. Water boils at 120 degrees—water alone will not work under extreme heat either. The fluid that most cars use is a mixture of water and ethylene glycol, also known as antifreeze. With a 50/50 blend of water and ethylene glycol, the boiling and freezing points are improved significantly.
Antifreeze also contains additives to resist corrosion and provides lubricant for the water pump bearings.
Check your fluids periodically—at least once a month. A routine top-off all around is a good practice.
