You can Select Your Vehicle to check if 12380-0A030 fits your vehicle.

Engine mounts seldom require attention, but broken or deteriorated mounts should be replaced immediately to prevent damage or wear on driveline components. During the check, the engine must be raised slightly to remove the weight from the mounts. Raise the vehicle and support it securely on jackstands, then position a jack under the engine oil pan with a large block of wood between the jack head and the oil pan. Carefully raise the engine just enough to take the weight off the mounts, avoiding positioning the wood block under the drain plug. Inspect the mounts for cracked, hardened rubber or separation from the metal plates, noting that the rubber may split down the center. Check for relative movement between the mount plates and the engine or frame using a large screwdriver or pry bar; if movement is noted, lower the engine and tighten the mount fasteners. Apply rubber preservative to the mounts to slow deterioration. To replace the mounts, disconnect the negative battery cable and raise the vehicle securely on jackstands if not already done. For the right engine mount, remove the two stays mounted on either side of the bracket on the engine, then remove the mount-to-bracket nuts and detach the mount. The rear mount bracket cradles the insulator, retained by a through-bolt to the chassis bracket; remove the through-bolt and the insulator bolts to take out the rear engine mount. For the front engine mount, remove the nut holding the insulator to the engine bracket, followed by the three bolts securing the insulator to the chassis. Additionally, there is a shock-absorbing mount between the engine and chassis, to the left of the conventional front engine mount; remove the through bolt connecting the mount to the suspension subframe, then the nut and bushing at the top of the shock absorber, and detach the shock from the engine bracket. Installation follows the reverse order of removal, using thread locking compound on the mount bolts and nuts, ensuring they are tightened securely.

For transaxle mount replacement, you can follow a similar procedure to engine mount replacement. The key steps involve supporting the transaxle and removing and installing the transaxle mount using appropriate fasteners and thread locking compound. Ensure that the transaxle mount is securely attached to prevent driveline issues.

To remove the engine movement control rod assembly in V6 models, you need to take out the two through-bolts and the engine movement control rod.

To check the engine mounts, you should raise the vehicle and securely support it on jackstands. Position a jack under the engine oil pan and place a large block of wood between the jack head and the oil pan. Raise the engine slightly to remove the weight from the mounts. Do not position the wood block under the drain plug. Then, visually inspect the mounts for signs of damage and use a large screwdriver or pry bar to check for any movement. If movement is observed, lower the engine and tighten the mount fasteners. Applying rubber preservative to the mounts can help slow down deterioration.

Installation is the reverse of removal. Use a non-hardening thread locking compound on the mount bolts/nuts and ensure they are tightened securely.

V6 models have a shock absorbing mount, which is mounted between the engine and chassis. It is located to the left of the conventional front engine mount.
