LG Motorsports LG Diff and Trans Cooler - Manual (Page 7)

Now that the pump is mounted, your fittings are installed into the trans and diff it is time
to start running the lines. Take note of the line lengths and fittings in the item list above
to note which line will be used in each location. Start by running the diff lines from the
factory drain location into the left side of the pump at the first location. Continue by
running the out line to the cooler, and cooler back to the diff at the factory fill. Don’t
worry once all of the lines are ran for both the trans and diff we will go back and fill the
units before starting the car. Do the same for the transmission. Make sure before
securing the fittings that the lines lay away from any moving parts and are held tight
against the frame rails going to the coolers as shown in figures 5 and 6 above. Using
some Adel clamps and zip ties make sure the lines are secure and tighten all fittings other
than the fill ones.
Before starting the car you will now want to fill the diff and trans full of fluid and hand
tighten the fittings at the fill locations once you have filled the units just like you would
stock. Make sure the car is secure and will not move as you need to start the car and run
the car through 1
st
and 2
nd
gear for a short period of time to circulate the fluids thru the
lines and coolers. Once you have finished this, remove the fill line and top off the trans
and diff to level and tighten the lines.
You can now re-install the inner fender liner, check for leaks, install the tires, and enjoy
your new drivetrain cooling system!
