You absolutely must consult a factory service manual for your specific year and model Dodge vehicle. This manual will provide the correct torque specifications for each individual bolt on the exhaust manifold. Using an incorrect torque specification can lead to leaks, damage to the manifold or cylinder head, and even engine failure.
You can usually find these manuals online through sites like eBay or online automotive parts retailers. Alternatively, a local mechanic or auto parts store may have access to this information. Do not rely on generalized information found online for this critical repair.
