HOOD LATCH & HINGES
Clean the latch surfaces and apply clean engine oil to the latch pilot bolts and the spring anchor. Use the engine oil to lubricate the hood hinges as well. Use a chassis grease to lubricate all the pivot points in the latch release mechanism.
The gas tank filler door, car door, and rear hatch or trunk lid hinges should be wiped clean and lubricated with clean engine oil. Silicone spray also works well on seals, but must be applied more often. Use engine oil to lubricate the trunk or hatch lock mechanism and the lock bolt and striker. The door lock cylinders can be lubricated easily with a shot of silicone spray or one of the many dry penetrating lubricants commercially available.
PARKING BRAKE LINKAGE
Use chassis grease on the parking brake cable where it contacts the guides, links, levers, and pulleys. The grease should be water resistant for durability.
Lubricate the throttle lever, and the accelerator pedal lever at the support inside the car with clean engine oil.
TRANSMISSION SHIFT LINKAGE
Lubricate the shift linkage with water resistant chassis grease which meets GM Specification 6031M or its equal.
