Oil Adjusting Procedure for Compressor Replacement

WARNING: This page is about a different car, the 2019 Nissan NV3500 HD, 2019 Nissan NV2500 HD, and 2019 Nissan NV1500. However, it is still accessible from the selected car via links, so may be relevant.

Drain oil from removed compressor and measure oil amount.

Measure total amount of oil that is drained from removed compressor.
NOTE: VK56VD shown, VQ40DE similar.

Drain oil from a new compressor that is calculated according to the following conditions.

Amount to be drained (A) [m (US fl oz, Imp fl oz)] = F - (D + S + R + ±)
F	: Oil amount that a new compressor contains [210 (7.1)]
D	: Oil amount that is drained from removed compressor
S	: Oil amount that remains inside of removed compressor [20 (0.7)]
R	: Oil amount to be added according to components that are removed except compressor
±	: Oil amount that is recycled together with refrigerant during recycle operation

CAUTION: If oil amount that is drained from removed compressor is less than 60 m

(2.0 US fl oz, 2.1 Imp fl oz), perform calculation by setting "D" as 40 m

(1.4 US fl oz, 1.4 Imp fl oz).

Conditions		m (US fl oz, Imp fl oz)
Replace evaporator		75 (2.5, 2.6)
Replace condenser		75 (2.5, 2.6)
Replace liquid tank		5 (0.2, 0.2)

Example: Oil amount to be drained from a new compressor when replacing compressor and liquid tank [m (US fl oz, Imp fl oz)] [D = 60 (2.0, 2.1), ± = 5 (0.2, 0.2)]

210 (7.1, 7.4) - [60 (2.0, 2.1) + 20 (0.7, 0.7) + 5 (0.2) + 5 (0.2, 0.2)] = 120 (4.1, 4.2)

Install compressor and check the operation.
