⁽¹⁾	Capacities are recommended or calculated levels. Always use dipstick (if available) to measure level.

⁽²⁾	Use of R-12 in a R134a system will result in SEVERE DAMAGE.

⁽³⁾	Use R-134a refrigerant & PAG refrigerant Oil (P/N 5416939).

⁽⁴⁾	Total quantity required may be higher, dependent upon fluid cooler size and the length and diameter of fluid lines.

⁽⁵⁾	Add two sealant pellets (GMSPO P/N 3634621) when cooling system is drained and refilled with new coolant.

⁽⁶⁾	Follow proper refilling procedures to eliminate cooling problems due to air being in system.

⁽⁷⁾	Includes Filter

When to See a Mechanic

• You smell fuel, burning insulation, or see smoke.

• Brakes feel soft, pull hard to one side, or make grinding noises.

• The engine overheats, stalls repeatedly, or misfires under load.

• You are missing required tools, torque specs, or safe lifting equipment.

• You are not confident in the next step or safety outcome.
