  Q: How to replace the ENGINE OIL COOLER HOSE/PIPE for 4WD on Chevrolet Avalanche 1500?

  A: To replace the engine oil cooler like/pipes for 4wd vehicles, one should first remove the engine oil cooler quick connect fittings. For engines of 5.3l or 6.0l, use the screwdriver to remove the Oil Cooler Hose from the clip on the lower Fan Shroud and unlock the vehicle from the ground by lifting it with help. For 8.1l engines, remove the hoses from the clip and raise and support the vehicle with jack or utility stands at the rear, if equipped, remove the engine protection shield, and front differential carrier shield. Enplace an adjustable jack under the front differential carrier, remove inner axle housing nuts and washers and the differential carrier upper mounting bolt and nut. Pivot the differential carrier forward and down with the jack supporting it, secure it, and remove the lower mounting bolt and nut, and thenze the jack 4-6 inches. For 5.3 and 6.0l, remove the bolt on the Oil Cooler Hose bracket, the drill bolts on the Oil Cooler Hose adapter, and the Oil Cooler Hose assembly with the gasket, discard the gasket, and check the fittings, connectors, and hoses for defects. For 8.1l engines, first remove the Oil Cooler Hose bracket bolt, and then remove the quick connect fittings at the engine and the Oil Cooler Hose assembly, discarding the gasket and inspect for damages in the fittings, connectors, and hose assembly. If it is installed with an 8.1l engine, install the new Oil Cooler Hose assembly together with the gasket, the quick connect fittings at the engine must feel a distinct snap, install the Oil Cooler Hose bracket bolt that should be tightened up to 50 nm (37 ft. Lbs.). To install Oil Cooler Hose assembly for 5.3l or 6.0l engines, install the new gasket and than install the oil filter cooler hose adapter bolts with 12 nm (106 inch lbs.) and oil filter cooler hose bracket bolts with 25 nm (18ft-pounds). Lift the jack to place the differential carrier, install the lower mounting bolt and nut, swing the carrier up and back, install the nut and bolt of the upper mounting and do not tighten it yet. Install the inner axle housing washers and nuts, torquing them to 100 nm (75 ft. Lbs ), and the upper and lower differential carrier bolts to 100 nm (75 ft. Lbs). Take out the adjustable jack, reinstall the front differential carrier shield and engine protection shield if equipped and remove the jack or utility stand from the rear and lower it. For 8.1l engines install a plastic cap on end of oil cooler line connecting to quick connect fitting before install as well as to the oil cooler hoses to the clip. For 5.3l or 6.0l engines, attach the hoses to the hose clip on the Fan Shroud and clip it closed making sure that the oil cooler line has a plastic cap prior to installation and finish up by attaching the oil cooler lines to the Radiator.
