For internally lubricated V3 units only

This supercharger has been factory pre‑lled with spe-

cial Vortech synthetic lubricant. Oil does not need to be

added to a brand new unit; however a uid level check

should be performed.

Prior to operating the supercharger on the vehicle and

after installation onto the vehicle:

Remove the factory installed at‑head brass shipping

plug (not the dipstick) from the top of the supercharger

case. Replace the sealed shipping plug with the sup-

plied “vented” plug. Do not operate the supercharger

without it. Check the supercharger uid level.

Fluid level checking procedure:

1. Ensure that the .06” copper sealing washer is

located on the dipstick base.

2. Thread the clean dipstick into the supercharger

unit it seats.

3. Once the dipstick has seated, remove the dip-

stick from the unit. Fluid should register in the

crosshatched area on the dipstick.

4. DO NOT OVERFILL!!! Drain excess fluid the

unit if it is above the maximum level on the dip-

stick.

Check the uid level using the dipstick at least every

2,500 miles.

Initial supercharger uid change must be performed at

2,500 miles. The supercharger uid must be changed

at least every 7,500 miles.

Drain the uid, rell the unit with 4 oz. of Vortech V3

lubricating uid and then conrm proper oil level using

the dipstick. DO NOT OVERFILL!!!

lubricant will void the warranty and may cause compo-

nent failure.
