GMC Yukon SLT 2005 Automatic Gasoline 4WD Peace, mercy, and blessings of God be upon you. The car is very clean, 4x4 is working. Engine and gearbox are guaranteed. New original water pump and thermostat installed, radiator water changed, and the entire cooling system checked. AC is freezing. Engine has been tuned up. It gives you 550 to 600 km per tank in the city with AC on. On the highway, forget about fuel consumption; it will take around 750 km or more. Even though I haven't changed the spark plugs yet, I only cleaned the throttle body and the air and exhaust sensors, and added a resistor that helps with fuel consumption. The resistor is installed if you have removed the catalytic converters. Removing them increases performance and allows the engine to breathe better, and with the resistor, the sensor reads correctly and saves more fuel. The car has a mileage of just over 400,000. 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.
