How do you put coolant in gmc Yukon?

To add coolant to a GMC Yukon, first ensure the engine is cool and locate the coolant reservoir, usually found near the front of the engine bay. Remove the cap from the reservoir and check the coolant level; if it's low, add a 50/50 mixture of antifreeze and distilled water until it reaches the appropriate level. Replace the cap securely and check for any leaks. Always consult your owner's manual for specific recommendations regarding coolant type and maintenance.
