GMC Envoy XUV Automobile User Manual


 
(f) Lubricate all key lock cylinders, hood latch assembly,
secondary latch, pivots, spring anchor, release pawl,
rear compartment hinges, outer liftgate handle pivot
points, rear door detent link, roller mechanism, liftgate
handle pivot points, latch bolt, fuel door hinge, cargo
door hinge, locks and folding seat hardware. More
frequent lubrication may be required when exposed to a
corrosive environment. Applying silicone grease on
weatherstrips with a clean cloth will make them
last longer, seal better and not stick or squeak.
(g) Check vent hose at transfer case for kinks and
proper installation.
(h) Change automatic transmission fluid and filter if the
vehicle is mainly driven under one or more of these
conditions:

regularly reaches 90°F (32°C) or higher.

When doing frequent trailer towing.
Uses such as found in taxi, police or delivery
service.
(i) Drain, flush and refill cooling system. This service
can be complex; you should have your dealer perform
this service. See Engine Coolant on page 5-25 for
what to use. Inspect hoses. Clean radiator, condenser,
pressure cap and filler neck. Pressure test the cooling
system and pressure cap.
(j) A fluid loss in any vehicle system could indicate a
problem. Have the system inspected and repaired and
the fluid level checked. Add fluid if needed.
(k) If you drive regularly under dusty conditions,
inspect the filter at each engine oil change.
