Q: How to replace the radiator on a Body VIN Type 3 (GMT 360) on GMC Envoy?
A: The first step when replacing the body vin type 3 (GMT 360) Radiator involves draining the coolant from the Radiator while recovering refrigerant. Before proceeding with the Radiator replacement start by lifting the vehicle so you can uninstall the lower Radiator support shield when it is present. Use hose clamp pliers (J 38185) to shift the outlet Radiator Hose clamp after which you can remove the outlet hose from its location on the Radiator. The next step requires you to disconnect both transmission cooler lines before lowering the vehicle down. Start the repair by removing the cooling fan and shroud elements and continuing with removal of the Radiator support diagonal brace then the coolant recovery line. Remove the Radiator by disconnecting its side panels from the shroud before removing both components and their retaining bolts to the condenser. Installation starts by attaching the condenser to the Radiator while installing its bolts before tightening them to 28 nm (21 ft. Lbs.). Installation involves placing the Radiator followed by inserting the cooling fan together with the shroud. Raising the vehicle enables the installation of the outlet Radiator Hose while hose clamp pliers (J 38185) help reposition the outlet Radiator Hose clamp before connecting transmission cooler lines. Follow this procedure: first lower the vehicle then install the coolant recovery hose and the Radiator diagonal brace and the lower Radiator support shield before filling the cooling system.
A: You must eliminate the Fan Shroud before lifting the vehicle high enough to remove the Radiator. Users should apply hose clamp pliers (J 38185) to relocate the outlet hose clamp from the Radiator before removing the outlet Radiator Hose. The Radiator work requires the removal of transmission cooler lines and then vehicle lower positioning followed by removing this hose from the inlet. Raising the vehicle enables access to detach the condenser from the Radiator by first removing the Radiator mounting bracket bolt and the Radiator mount and the grill and condenser mounting bolts. You should start by installing the Radiator and afterward connect the condenser to it before tightening all bolts to 28 n.m (21 lb ft). Then secure the grille as well as the Radiator mount bracket and the Radiator mounting bracket bolt while tightening them to 28 n.m (21 lb ft). When the vehicle reaches its previous height install the Radiator outlet hose to the Radiator while you position the Radiator outlet hose clamp using hose clamp pliers (J 38185) and connect the transmission cooler lines before lowering the vehicle to add the Radiator vent inlet hose and the Fan Shroud.
Q: How to replace the radiator for the 4.3L, 4.8L, 5.3L, and 6.0L engines on GMC Sierra 1500?
A: The first step for basic Radiator replacement on engines with 4.3l, 4.8l, 5.3l, and 6.0l requires cooling fan and shroud removal. Proceed by removing the Radiator outlet hose which corresponds to the engine model. Engine oil cooler lines should disconnect from the Radiator only when equipped followed by transmission oil cooler lines which also need disconnecting if equipped. Begin by discharging both Radiator bolts before pulling out the Radiator from its position. After placing the new Radiator into its correct position you should tighten the Radiator bolts until they reach 25 nm (18 lb ft). Seam the transmission cooling lines to the Radiator before reconnecting the engine oil lines to their proper slot. End the procedure by installing the outlet hose based on engine type and reinstalling the cooling fan and shroud.
