CATExhaust & Turbo

8N2368 Shield As — Cat Engine: 637g 657e

This heat shield is designed to protect surrounding engine components from the intense heat generated by the exhaust system. It is constructed from durable, high-temperature resistant materials to maintain its integrity under extreme operating conditions, unlike a damaged shield which may warp or crack. Operators may notice increased under-hood temperatures or unusual heat radiating from the exhaust manifold area if this shield is compromised.

Installation & Application Notes

Allow turbo to idle 2–3 minutes before shutdown — this circulates oil through bearings and prevents coking. Check oil feed and drain lines for blockages before fitting new turbo. Replace oil and filter when fitting new turbo — old oil contains metal particles.

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

Failure Symptoms

Visible signs of damage such as cracks or deformation are the first indicators of a failing heat shield. If left unaddressed, the shield's protective function diminishes, leading to increased heat exposure for nearby components. This can result in accelerated wear on hoses, electrical wiring, and other sensitive parts in the vicinity of the exhaust.

Installation Tip

Ensure the mounting surfaces are clean and free of debris before installation to achieve a proper seal. Do not overtighten mounting bolts, as this can distort the shield or damage the exhaust manifold.

Service Note

Inspect exhaust manifold gaskets and mounting hardware for signs of leakage or damage during heat shield replacement.
