Above directions are for oil cooler installed in pressure side of system. This is the preferred way to cool the LS 7 System providing the factory pressure pump maintains adequate oil pressure. Loss of pressure can sometimes occur due to extra distance & flows of oil through cooler. The oil cooler may also be installed in scavenge return lines to tank. ie 7-2 or 16-3 (stage III)

First oil Filling

The System will hold between 9 and 12 quarts (existing holds 8 quarts)

1.      Do NOT add oil to the tank at time of installation of the pan (as oil will flow into the pan

2.      Through the red cap on the oil tank, pour say 8 quarts of oil, Add 2 quarts to Engine

3.      Crank the engine (plugs removed) to build up oil pressure

4.      Replace the plugs

5.      Start the engine and allow to warm to operating temperature

6.      Oil Pressure should stabilize around 50 PSI or more

7.      After checking pressure, leaks etc, turn off engine and immediately open the red cap and check the oil level

8.      Add oil until the oil level is just AT (NOT ABOVE) the level of the internal deaerater. (Slots)

NOTE: It is very important that when checking tank oil level (#8 above) that the engine has been run above idle, and shut off when level in tank checked not more than 5 minutes after shutting engine off #7, #8 above.
