coolant CADILLAC CTS 2004 1.G Owner's Guide

(h)Change automatic transmission uid and lter if
the vehicle is mainly driven under one or more of
these conditions:
In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as high performance operation.
If you do not use your vehicle under any of these
conditions, the uid and lter do not require changing.
(i)Drain, ush and rell cooling system. See Engine
Coolant on page 5-29for what to use. Inspect hoses.
Clean radiator, condenser, pressure cap and ller neck.

(j)Replace the belt (or every 96 months, whichever
occurs rst). Failure to follow the maintenance described
may result in a broken timing belt and could cause
severe engine damage. It is important to use only
genuine GM parts when replacing the timing belt.
(k)A uid loss in any vehicle system could indicate a
problem. Have the system inspected and repaired
and the uid level checked. Add uid if needed.(l)Change uid if the vehicle is used for high
performance operation.
(m)Change uid whenever the vehicle has been driven
for 3,000 miles (5 000 km) with the transmission
temperature at 290°F (143°C) or higher without using
an auxiliary uid cooler. See Message Center (CTS-V)
on page 3-53andTransmission Fluid Hot Message
on page 3-57.
