For newer Tahoes (roughly 2015 and newer):
* Fluid Changes: This is the most crucial aspect. You'll need to change your:
* Engine Oil & Filter: Follow the recommended oil type and change interval specified in your owner's manual. This is usually every 5,000-7,500 miles, but can vary depending on driving conditions.
* Transmission Fluid: Check your owner's manual for the recommended change interval. This is often longer than oil changes, sometimes 100,000 miles or more for some transmissions.
* Coolant (Antifreeze): Usually a 5-year or 100,000-mile interval, but check your manual.
* Brake Fluid: Every 2-3 years is a good rule of thumb, but consult your owner's manual.
* Power Steering Fluid: Check your owner's manual; less frequent changes are typically needed on newer vehicles.
* Differential Fluid: Check your owner's manual. This is usually a longer interval, potentially every 60,000 miles or more.
* Filter Changes: Besides the oil filter, you should also change:
* Air Filter: Every 12,000-15,000 miles, or more frequently if driving in dusty conditions.
* Cabin Air Filter: Every 12,000-15,000 miles, or more frequently if you have allergies.
* Spark Plugs (if applicable): Newer Tahoes may use iridium plugs that last much longer than older copper plugs. Check your owner's manual for the recommended replacement interval. This isn't a frequent service on modern vehicles.
* Inspection: Visually inspect belts, hoses, and other components for wear and tear. Replace anything that looks cracked, frayed, or damaged.
* Tire Rotation & Balancing: Rotate your tires every 5,000-7,500 miles to promote even wear. Get them balanced as needed.
* Battery Inspection/Replacement: Have your battery tested regularly.
For older Tahoes (pre-2007):
Many of the above still apply, but you'll likely need to add:
* Distributor Cap and Rotor: (If equipped with a distributor - many didn't, especially the later V8s.)
* Ignition Wires: Check for cracks or damage.
* PCV Valve: A worn PCV valve can cause poor performance.
Important Considerations:
* Owner's Manual: Always consult your vehicle's owner's manual for the manufacturer's recommended maintenance schedule. This is the most reliable source of information for your specific Tahoe.
* Professional Service: If you're not comfortable performing these tasks yourself, take your Tahoe to a qualified mechanic. Many of these tasks, especially fluid changes and inspections, are best left to professionals.
* Check Engine Light: If the check engine light is on, get the code scanned by a mechanic to determine the problem. Ignoring it can lead to more serious issues.
In short, a "tune-up" for a modern Tahoe is more about preventative maintenance and regular fluid changes than replacing individual parts like in the past. For older models, some additional components might require attention. Always prioritize consulting your owner's manual for specific recommendations.
