When & How

Get the Most out of OEM Antifreeze/Coolant

It’s important whenever antifreeze/coolant loss occurs to replace the antifreeze as soon as possible. You know when to replace the antifreeze in your vehicle if your thermometer reading goes into red. Typically antifreeze loss is caused by a leak and can usually be determined by a puddle of coolant beneath your vehicle.

Check the Antifreeze/Coolant Levels in Your Vehicle

Directions :
  1. Ensure the car engine is cool. Never check the radiator when the engine is hot or cold.
  2. Use a rag to remove the cap of the radiator tank.
  3. Check the radiator’s coolant level; the fluid should be near the top, or at the “Full” mark etched into the radiator metal (if there is one). If the level is low, you will have to top it up.
  4. If your car also has a radiator overflow tank, remove the cap. There should be little to no fluid present. If the coolant level is low in the radiator and nearly full in the overflow tank long after the car has been driven, take the car in for servicing immediately.
  5. Check the coolant’s protection level (freezing and boiling points) with a coolant refractometer. It is the best tool to measure glycol content and protection levels.
Refer to your owner’s manual for specific cooling system capacity and service instructions prior to changing your vehicle’s antifreeze/coolant. Ideal times to perform coolant tests are in the spring and fall. Check more often if you drive in extreme weather conditions throughout the year.

Top Up the Antifreeze in Your Vehicles Cooling System

Directions :
  1. Add your matched OEM antifreeze to within 1” (2.5 cm) of the radiator cap, topping off overflow bottle to the cold fill line.
  2. Check the level again in 48 hours. If it is below the cold fill line, inspect the system for leaks.
Refer to your owner’s manual for specific cooling system capacity and service instructions prior to changing your vehicle’s antifreeze/coolant. Ideal times to perform coolant tests are in the spring and fall. Check more often if you drive in extreme weather conditions throughout the year.

Change the Antifreeze/Coolant in Your Vehicle

Directions :
  1. Once the cooling system has been drained of antifreeze, fill with deionized water.
  2. Run engine until warm with heater on high.
  3. Thoroughly drain system again. Repeat until drained water is clear.
  4. Add antifreeze. Use minimum 50/50, maximum 70/30 antifreeze to deionized water mix. Run engine until warm.
  5. Top off with deionized water.

Flush and Fill your Vehicles Cooling System

Directions :
  1. Drain cooling system of used antifreeze.
  2. Fill system with deionized water and run engine until warm with heater on high.
  3. Drain system again and repeat until drained water is clear.
  4. Add your matched OEM antifreeze and run engine until warm.
