and new (unused) coolant together in the vehicle. Mixing of engine

coolants may harm your engine’s cooling system. The use of an

improper coolant may harm engine and cooling system components

and may void the warranty. Refer to Maintenance product

specifications and capacities in this chapter.

Note: Do not use stop leak pellets or cooling system sealants/additives

as they can cause damage to the engine cooling and/or heating systems.

This damage would not be covered under your vehicle’s warranty.

• A large amount of water without engine coolant may be added, in case

of emergency, to reach a vehicle service location. In this instance, the

cooling system must be drained and refilled with a 50/50 mixture of

engine coolant and distilled water as soon as possible. Water alone

(without engine coolant) can cause engine damage from corrosion,

overheating or freezing.

• Do not use alcohol, methanol, brine or any engine coolants

mixed with alcohol or methanol antifreeze (coolant). Alcohol

and other liquids can cause engine damage from overheating or

freezing.

• Do not add extra inhibitors or additives to the coolant. These

can be harmful and compromise the corrosion protection of the engine

coolant.

For vehicles with overflow coolant systems with a non-pressurized cap

on the coolant recovery system, add coolant to the coolant recovery

reservoir when the engine is cool. Add the proper mixture of coolant and

water to the FULL COLD level. For all other vehicles which have a

coolant degas system with a pressurized cap, or if it is necessary to

remove the coolant pressure relief cap on the radiator of a vehicle with

an overflow system, follow these steps to add engine coolant.

WARNING: To reduce the risk of personal injury, make sure the

engine is cool before unscrewing the coolant pressure relief cap.

The cooling system is under pressure; steam and hot liquid can come

out forcefully when the cap is loosened slightly.

Add the proper mixture of coolant and water to the cooling system by

following these steps:

1. Before you begin, turn the engine off and let it cool.

2. When the engine is cool, wrap a thick cloth around the coolant

pressure relief cap on the coolant reservoir (a translucent plastic bottle).

Slowly turn cap counterclockwise (left) until pressure begins to release.
