Radiator Assembly

Draining the cooling system should be your first step before raising the vehicle. Support it correctly for the next process. Placing a pan under vehicles with automatic transmission becomes essential to catch leaking fluid during the removal process of right and left engine splash shields. Start by disconnecting transmission fluid cooler hoses from the Radiator when removing its hose clamps. After that loosen the lower Radiator outlet hose clamp and remove its connecting hose. Perform the following procedure one: lower the car and detach the 2 upper Radiator bracket bolts and afterward detach the four a/c condenser bolt setup if your model has these components installed. First disconnect both cooling fan electrical connectors and then loosen the clamp on the upper Radiator inlet hose before separating the hose from the inlet. Separate the Radiator overflow hose by untightening the clamp to disconnect it from the Radiator filler neck area. Dismount the Radiator with cooling fan assembly from the automobile and move essential components from the original Radiator to the new one. Before assembly install the Radiator with the cooling fan in the vehicle and fasten the upper bolts at 13 nm (9 ft. Lbs.) tension and tighten the a/c condenser bracket bolts to 10 nm (89 inch lbs.). Position the overflow hose over Radiator filler neck flares and use a hose clamp for attachment. The Radiator inlet hose requires connection to the Radiator through similar installation. Finally, reconnect the cooling fan electrical connectors. After raising the vehicle to its stable position you should install the transmission fluid cooler hoses onto the Radiator while tightening them with hose clamps. The outlet Radiator Hose needs installation at the Radiator's positioning above the flares then clamping with a hoseclamp. After inserting the right and left engine splash shields the vehicle should be lowered while you fill the Radiator with approved coolant up to the base of the filler neck while checking for overheating during engine operation with the cap removed. Let the engine operate until the coolant warms to its operational temperature which will be clear through flowing coolant and heated hoses. Follow the Radiator filler neck until successively adding coolant before installing the Radiator cap. A thorough examination should be carried out on the Radiator while checking coolant reservoirs and coolant pipe connections and hose connections for leaks with necessary connection tightening followed by Radiator cap installation and transmission fluid level verification on automatic transmission vehicles.

Disconnect both cooling fan electrical connectors.

Loosen the upper radiator inlet hose clamp and disconnect the upper radiator inlet hose, then loosen the radiator overflow hose clamp and disconnect the radiator overflow hose from the radiator filler neck.
