Cadillac 2007 CTS, Owner'S Manual, Page: 356 / 518

How to Add Manual Transmission Fluid
Here is how to add fluid. See Recommended
Fluids and Lubricants on page 474 to determine
which type of fluid to use.
1. Remove the filler plug.
2. Add fluid at the filler plug hole. Add only
enough fluid to bring the fluid level up to
the bottom of the filler plug hole.
3. If your vehicle is a CTS, replace the gasket
and reinstall the filler plug. If your vehicle is a
CTS-V, apply LOCTITE
®
#516 or equivalent
sealant to the threads and then reinstall
the filler plug.
Again, with either vehicle, be sure the plug is
fully seated.
Hydraulic Clutch
It is not necessary to regularly check clutch fluid
unless you suspect there is a leak in the system.
Adding fluid will not correct a leak.
A fluid loss in this system could indicate a
problem. Have the system inspected and repaired.
When to Check and What to Use
The hydraulic clutch fluid
reservoir cap has this
symbol on it. See
Engine
Compartment Overview
on page 342
for
reservoir location.
Refer to the Maintenance Schedule to determine
how often you should check the fluid level in
your clutch master cylinder reservoir and for the
proper fluid to use. See
Owner Checks and
Services on page 469 and Recommended Fluids
and Lubricants on page 474 .
How to Check and Add Fluid
Make sure the fluid level is at the MIN (Minimum)
line on the side of the reservoir. If it is not,
remove the cap and add the proper fluid until the
level reaches the MIN line.
