Prime antifreeze+coolant (concentrate) is for all vehicles; all makes, models, years & fluid colors. The extended life formula is safe for use with all types of metals & rubbers; including aluminum. Prestone Prime will guard against temperature extremes and the effects of rust, corrosion and premature water pump failure.

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 manufacturers maintenance schedule for more information.

DRAINthe cooling system to remove loose rust and sediment from the radiator. Follow owners manual (ILLUS. 1a).
FLUSHthe system using a quality product like PrestoneFlush and Cleaner to clean the engine block (ILLUS. 2a).
FILLwith PrestoneConcentrate 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:
REMOVEpressure cap WITH THE ENGINE COLD.
FILLtank with Prestone50/50 Prediluted Antifreeze/Coolant to cold fill line.
REPLACEcap securely* (ILLUS. 1b).

For Vehicles with Recovery Bottle and Pressure Cap on Radiator:
REMOVEradiator cap WITH THE ENGINE COLD.
ADDPrestone50/50 Prediluted Antifreeze/Coolant to within one inch of the top of the radiator cap.
TOP OFFrecovery bottle to cold fill line* (ILLUS. 2b).
