• Q: How to replace the radiator (LH6, LS2) for 5.3L and 6.0L engines on 2008 Chevrolet Trailblazer?

  A: For Radiator replacement (LH6, LS2) of 5.3l and 6.0l engines start by draining the coolant from the Radiator. Start by removing the lower Radiator support shield when present and disconnect the transmission cooler lines from the Radiator. The hose clamp pliers (J 38185) will help with securing the outlet Radiator Hose clamp in position before concerned users can detach the outlet Radiator Hose from the Radiator. Use the hose clamp pliers (J 38185) while lowering the vehicle to reposition the inlet Radiator Hose clamp. The first step involves removing and setting aside the cooling fan with its shroud then moving on to unfastening the air inlet grille afterwards and finally separating the coolant recovery line from the Radiator. Begin the process by removing the upper Radiator to condenser bolts then lifting the condenser to free it from the Radiator retaining tab before finishing by removing the Radiator. Position the new Radiator in its place before installing the condenser to the Radiator retaining tab and tightening its bolts to 28 n.m (21 lb ft). Reconnect the coolant recovery line after you return the air inlet grille to its place along with the cooling fan and shroud. You should use hose clamp pliers (J 38185) to properly position the inlet Radiator Hose clamp after installation of the inlet Radiator Hose. First elevate the vehicle to install the outlet Radiator Hose after which you should clamp the Radiator Hose position using hose clamp pliers j 38185. The Radiator cooler lines receive their installation before reinstalling the lower support shield (when present), while the vehicle descends and the cooling system requires fluid. You will need the fan clutch remover and installer (J 41240) according to process requirements.
