Hello I will help you with your question,

 

This is the schedule I recommend,

 

Your coolant every four years, the spec is five years but that is too long in my opinion.

 

Your brake fluid every three years or when a copper/moisture test exceeds limits

 

Transmission fluid every 60000 miles unless you tow often then flush accordind to fluid condition

 

This is the AllData recommendation at 30000 miles and you can find GMs in the back of the owners manual

 

Check
	Coolant		Notes
		Check engine coolant fluid level and add fluid as needed.
	Fluid - A/T		Notes
		Check the transmission fluid level and add fluid as needed.
	Washer Fluid		Notes
		Check windshield washer fluid level and add fluid as needed.
Inspect
	Brakes and Traction Control		Notes
		Inspect Brake System. Visually inspect brake lines and hoses for proper hook-up, binding, leaks, cracks, chafing, etc. Inspect disc brake pads for wear and rotors for surface condition. Inspect other brake parts, including calipers, parking brake, etc.
	Cooling System		Notes
		Inspect engine cooling system. Visually inspect hoses - replace if cracked, swollen or deteriorated. Inspect all pipes, fitting, clamps. Pressure test system and cap and clean outside of radiator and air conditioning condenser at least once a year.
	Exhaust System		Notes
		Inspect exhaust system for damage or loose components.
	Fuel Supply Line		Notes
		Inspect fuel system for damage or leaks.
	Restraint Systems		Notes
		Make sure the safety belt reminder light and all your belts, buckles, latch plates, retractors and anchorages are working properly. Look for any other loose or damaged safety belt system parts. If you see anything that might keep a safety belt system from doing its job, have it repaired. Have any torn or frayed safety belts replaced. Also look for any opened or broken air bag coverings, and have them repaired or replaced. The air bag system does not need regular maintenance.
	Suspension		Notes
		Inspect suspension and steering components. Visually inspect front and rear suspension and steering system for damaged, loose, or missing parts, signs of wear or lack of lubrication. Inspect power steering lines and hoses for proper hook-up, binding, leaks, cracks, chafing, etc. Pickup models: Visually check constant velocity joints, rubber boots, and axle seals for Visually inspect front and rear suspension for damaged, loose,or missing parts, signs of wear or lack of lubrication. Visually check constant velocity joints, rubber boots and axle seals for leaks.
	Vehicle		Notes
		Visually check for any leaks or damage. 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.
	Wiper Blade		Notes
		Inspect the wiper blades. Inspect wiper blades for wear, cracking, or contamination. Clean the windshield and wiper blades, if contaminated. Replace wiper blades that are worn or damaged.
Lubricate
	Doors		Notes

More frequent lubrication may be required when exposed to a corrosive environment. Applying silicone grease on weather-strips with a clean cloth will make them last longer, seal better and not stick or squeak.
	Steering and Suspension		Notes
		Lubricate chassis components. Lubricate the front suspension, steering linkage, transmission shift linkage, and parking brake cable guides. Control arm ball joints require lubrication but should not be lubricated unless their temperature is 10›1|F (-12›1|C) or higher, or they could be damaged. Vehicles used under severe commercial operating conditions require lubrication on a regular basis every 3,000 miles (5 000 km).
Replace
	Engine Oil		Notes
		Change engine oil and filter, or every 12 months whichever occurs first. Reset the oil life system.
