Coolant Mixture Correction Procedure
COOLANT MIXTURE CORRECTION1. Drain the entire cooling system (radiator, coolant reservoir tank, and cylinder block).
^ Refer to the applicable Service Manual (ESM), section MA, for coolant drain locations.
2. Refill the engine cooling system using Genuine Nissan Anti-freeze Coolant, mixed 50/50 with distilled water or de-mineralized water.
^ Use Engine Coolant Refill Tool #J-45695 to fill the radiator.
^ Refer to NTB02-011a for Engine Coolant Refill Tool #J-45695 information.
IMPORTANT:
It is very important that the engine cooling system be filled with a mixture that is no more then 55% coolant (ethylene glycol). Please be "precise" (accurate) when measuring.
In most areas it is best to use a 50% coolant / 50% water mixture. The freezing point of a 50/50 mixture is - 34 degrees F.
If freeze protection down to - 47 degrees F is needed, a 55% coolant / 45% water mixture may be used.
To account for spillage during refill, and the extra mixture needed to keep the refill tool and "bleed" tool from running dry, we recommend a full mixture: 12 quarts / 3 gallons.
The measurements shown above will give you 12 quarts / 3 gallons of a 55/45 mixture.
^ If a refractometer is available, it is best to recheck the coolant mixture after mixing to confirm it is within 50 to 55% ethylene glycol.
^ Engine coolant capacity (with reservoir tank) is:
7.5 liters (7-7/8 quarts) for vehicles equipped with the 4-cylinder engine (QR25DE)
8.1 liters (8-5/8 quarts) for vehicles equipped with the 6-cylinder engine (VQ35DE)
^ Reservoir tank capacity is:
0.7 liters (3/4 quart) for both the QR25DE and VQ35DE engines
