Strut Mount, Driver Side

The first step for mounting a new front engine component requires that a technician raises and supports the vehicle above the ground. Disassemble the front Engine Mount by removing the two securing nuts from the engine frame and engine frame installation. Proceed by disconnecting both upper bolts which connect the front Engine Mount Bracket to the Cylinder Head and then the two nuts securing this bracket to the engine block. The brace bolt connecting to the transaxle must first be removed before removing the transaxle support brace. The procedures end by removing both the front Engine Mount along with the bracket. Start the front Engine Mount Bracket installation by positioning it against the engine while loosely installing its two upper bolts which fasten to the Cylinder Head. After installing the transaxle support brace, follow service precautions guidelines and torque the two lower front Engine Mount Bracket nuts as well as the transaxle support brace just minimally. The proper order for tightening fasteners includes installing lower Engine Mount Bracket nuts to 41 nm (30 ft. Lbs.), transaxle support brace bolt to 50 nm (37 ft. Lbs.), and finally the two upper Engine Mount brace bolts to 50 nm (37 ft. Lbs.). After securing the front Engine Mount to the engine frame through its nuts users should tighten the fasteners to 50 nm (37 ft. Lbs.). Finally, lower the vehicle.

Start engine mount strut replacement by taking out the bolt which extends through the strut from the core support along with any bracket attached to the core support. The engine mount torque struts must stay free of preload when they are installed into their position. You must leave the bolt attaching the strut to the core support bracket loose while assembling it because adjustment is possible at that point. Tighten the bolt to 78 nm (58 ft. Lbs.) before finishing the engine mount strut assembly process.

Service process for replacing engine mount struts consists of independent servicing because it preserves engine support integrity. The maintenance process starts with breaking the bolt which holds the engine mount strut at the engine before handling all three bolts which secure the strut to the radiator tie bar. The engine mount strut should be extracted from the vehicle after it has been removed from its position. Install the engine mount strut by returning it to position and fasten the three bolts to the radiator tie bar using 24 Nm (18 ft. lbs. torque value). The last installation task involves tightening the mount strut bolt to 78 Nm (58 ft. lbs.) while it secures the strut to the engine.

Install the two nuts securing the mount to the rail and tighten them to 70 Nm (52 ft. lbs.).

Remove the nut securing the engine mount to the engine mount bracket.

Take out the bolt securing the engine mount strut to the engine.

First, remove the engine mount strut, drive belt, and the bolt securing the power steering return hose to the right engine mount strut bracket, then set it aside.

Remove the two upper bolts securing the engine mount bracket to the engine.

Use a suitable jack to support the engine assembly.
