Changing Your Antifreeze And Coolant

Prestone knows how crucial routine maintenance of your cooling system is to the life of your vehicle. To properly maintenance your vehicle, follow the steps below.

If your coolant looks dirty, you need to replace it. Dirty coolant is no longer effective, which means corrosion, rust and damage happen more rapidly, along with reduced fluid flow and the risk of clogging. Drain and fill and flush and fill are the correct ways to deal with dirty coolant. Check your manufacturer’s maintenance schedule for more information.

DRAIN the cooling system to remove loose rust and sediment from the radiator. Follow owner’s manual (ILLUS. 1a).
FLUSH the system using a quality product like Prestone^® Flush and Cleaner to clean the engine block (ILLUS. 2a).
FILL with Prestone^® Concentrate and distilled water to achieve the freeze-up/boil-over protection indicated on the back of the bottle (ILLUS. 3a).

Top-off:

Low coolant means less heat transfer, which in turn risks the engine overheating. Too much coolant also risks damage to the system, as coolant needs room to expand when cold. Without this room, parts can become cracked and damaged. Make sure you regularly check your reservoir, and top off to the fill line as needed.

For Vehicles with Expansion Tank:
REMOVE pressure cap WITH THE ENGINE COLD.
FILL tank with Prestone^® 50/50 Prediluted Antifreeze/Coolant to “cold” fill line.
REPLACE cap securely* (ILLUS. 1b).

For Vehicles with Recovery Bottle and Pressure Cap on Radiator:
REMOVE radiator cap WITH THE ENGINE COLD.
ADD Prestone^® 50/50 Prediluted Antifreeze/Coolant to within one inch of the top of the radiator cap.
TOP OFF recovery bottle to “cold” fill line* (ILLUS. 2b).

*Check fluid level after 1-2 days. If consistency is low, have cooling system checked for leaks.

WARNING: DO NOT drink antifreeze or solution. Do not store in open or unlabeled containers. Avoid contact with eye, skin and clothing. Wash thoroughly after handling. Avoid breathing vapers or mist. Solution is poisonous to animals.

IF SWALLOWED, CALLED A POISION CENTER OR GO TO A HOSPITAL EMERGENCY ROOM IMMEDIATELY. If inhaled, move to fresh air. Seek medical attention if symptoms persist. In case of contact, wash with water.
