396-8052 Exhaust Manifold — Cat 120M 140

This exhaust manifold collects exhaust gases from multiple cylinders and directs them into the exhaust system, ensuring efficient engine breathing and emissions control. It is constructed from high-temperature resistant materials, unlike a cracked or warped manifold that can lead to exhaust leaks and reduced engine performance. Operators may notice increased exhaust noise, a loss of engine power, or the smell of exhaust fumes in the engine compartment when this manifold fails.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

An audible increase in exhaust noise, often described as a loud ticking or puffing sound, is a primary indicator of a failing exhaust manifold. If ignored, exhaust leaks can worsen, leading to reduced engine power, increased emissions, and potential damage to surrounding components from heat exposure. This can compromise engine performance and lead to costly repairs.

Installation Tip

Ensure the mounting surfaces on the cylinder head and exhaust system are perfectly clean and flat before installing new gaskets. Tighten manifold bolts in a crisscross pattern gradually to ensure even pressure distribution.

Service Note

Replace the exhaust manifold gasket and inspect the entire exhaust system, including pipes and muffler, for leaks or damage.
