If you want to service the engine oil cooler, first, disconnect the cooler lines from the radiator, since the one-time design means you must also unscrew the fittings from the block and
Oil Pan. After that, take out the fittings from the connections on the engine block and oil pan and afterward remove the lines from the support bracket and retainer as well. Joint control line from the pressure control valve and remove it by unscrewing the fitting from the engine. At the start, fit the radiator shell to your vehicle and tighten the oil cooler lines to ensure they fit well to the radiator inlets (it is recommended to use 18 Nm/160 in. lbs. torque). Screw the cooler lines into the radiator fittings and retainer clip, making certain the connection is tightened to 18 Nm (160 in. lbs.). For both new radiator and header coolers, put the fittings on the engine block and oil pan, tighten to the required torque, then place the lines in position and ensure they stay before clipping the lines to the brackets. If using the original cooler pipes, put them to the engine block and oil pan, tighten the fittings to 30 Nm or 260 in. lbs. and attach them to the support bracket. Connect the supply line to the engine block using the fitting, make it snug by tightening it to 30 Nm (260 in. lbs.), fit the control valve to the connection point so it locks and secure the remains of the supply line to the control valve, tightening thatconnector to the same pressure.
