The recommended engine oil for a 2009 GMC Yukon Denali is SAE 5W-30. It's best to use oil that meets GM specification GM6094M.
To troubleshoot the check engine light, use an OBD-II scanner to read the diagnostic trouble codes (DTCs). These codes can help identify the issue. Common causes include a loose gas cap, faulty oxygen sensor, or spark plug issues.
To replace the key fob battery, remove the key ring, open the fob using a small flathead screwdriver, and replace the old battery with a new CR2032 battery. Ensure the positive side faces down.

Common causes for overheating include a malfunctioning thermostat, low coolant levels, a faulty radiator fan, or a blocked radiator. Regular maintenance and checks can help prevent these issues.

It's recommended to check the transmission fluid level regularly and replace it every 50,000 to 100,000 miles under normal driving conditions. Use only the specified transmission fluid type.
To program a new key, insert an already programmed key into the ignition and turn it to the "On" position. Then, within five seconds, insert the new key and turn it to the "On" position. The security light should turn off, indicating successful programming.
