🔧 Optima - Engine Mount Replacement
On your Optima, “engine mounts” can mean more than one mount (the engine-side mount, the transmission-side mount, and the lower torque/roll mount). The exact steps and torque specs change depending on which mount you’re replacing, and using the wrong procedure can crack a mount bracket or damage the oil pan if it’s supported incorrectly.
Difficulty Level: Intermediate | Estimated Time: 1.5-4.0 hours (depends which mount)
⚠️ Safety & Precautions
- ⚠️ Never support the engine by the oil pan without a wood block; the pan can bend or crack.
- ⚠️ Keep hands clear when raising/lowering the engine with a jack; pinch hazard.
- ⚠️ Work on level ground and use jack stands; never rely on a jack alone.
- ⚠️ Let the engine cool before working near the turbo/exhaust side; burn hazard.
🔧 Required Tools
You'll need the following tools for this repair:
- Floor jack (rated 3-ton minimum)
- Jack stands (rated 3-ton minimum)
- Wheel chocks
- Safety glasses
- Mechanic gloves
- Socket set (8mm-19mm)
- 3/8" ratchet
- 1/2" breaker bar
- Torque wrench (10-200 ft-lbs range)
- Extension set (3", 6", 12")

- Take photos before removing brackets.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Quick confirmation (so I give the correct procedure)
- Tell me which mount you’re replacing: passenger-side (engine mount), driver-side (trans mount), lower torque/roll mount, or all mounts.
- Also tell me: are you hearing clunks on shifts/launch, or is the engine visibly rocking? This helps confirm you’re targeting the right mount.
Step 2: Pause here (I’ll send the exact steps + torque specs next)
- Once you answer the two items above, I’ll give you the exact Optima-specific removal order, safe engine support points, and the correct Torque to XX Nm (YY ft-lbs) specs for your mount(s).
✅ After Repair
- Re-check that every mount bolt/nut is tightened to spec before starting.
- Start the engine and watch for excessive movement with the hood open.
- Test drive gently and listen for new vibration or clunks.
