How to efficiently handle radiator replacement for the 4.3L, 4.8L, 5.3L, and 6.0L engines on GMC Sierra 1500?

Begin Radiator replacement for 4.3l and 4.8l as well as 5.3l and 6.0l engines by eliminating the cooling fan and covering it with the shroud. The replacement process requires the specific Radiator outlet hose detachment for each engine variant. The first step involves disconnecting the engine oil cooler lines from the Radiator only if it is present before disconnecting the transmission oil cooler lines as well if installed. Complete the Radiator replacement procedure by removing both Radiator bolts and finally removing the Radiator from the vehicle. Secure the new Radiator by placing it properly then fasten bolts at 25 nm (18 lb ft) torque setting. Connect transmission oil cooler lines first with engine oil cooler lines second if equipment includes this feature. Place the new Radiator in its position and tighten bolts to 25 nm (18 lb ft). Then install the Radiator outlet hose based on engine style before reattaching the cooling fan and shroud.
