GMC Yukon SLE 2005 Automatic Gasoline Peace, mercy, and blessings of God be upon you. The car is very clean, 4WD is working. Engine and gearbox are guaranteed. New original water pump and original thermostat installed, radiator water changed, and the entire cooling system checked. AC is ice cold. Engine tune-up completed. In the city, it goes from 550 to 600 km on a full tank, and with the AC on. On the highway, forget about fuel consumption. The highway will take around 750 km or more, even though I haven't changed the spark plugs yet. Just cleaned the throttle body, air sensor, and exhaust sensors, and added a connector that has a resistor for fuel consumption. The connector is installed if you have removed the catalytic converters. If you remove them, its power increases and the engine breathes better, and with the connector, the sensor reads correctly and saves more fuel. The car has a little over 400,000 km. The car has a noise in the differential that needs a rubber boot and lubrication only. All other aspects of the car are excellent, nothing else is wrong. Inspection is new. For sale to the highest bidder.
