Examine the exhaust manifold and gasket for damage.
If cracks or damage are found, remove the exhaust manifold by:
- Removing the bolts securing the manifold to the engine (use a socket set).
- Detaching the exhaust pipes connected to the manifold.

4. Replace Gaskets and Repair Leaks

Clean the mounting surfaces on both the manifold and cylinder head using a scraper.
Install new exhaust manifold gaskets.
If the manifold is damaged, consider replacing it with a new one.

5. Reassemble Exhaust System

Reattach the exhaust manifold to the engine, ensuring all bolts are tightened to manufacturer specifications (typically around 25-30 ft-lbs).
Reconnect any exhaust pipes or components that were removed.

6. Lower the Vehicle and Reconnect Battery
