Product Description
Product Introduction C3944593 Exhaust Manifold Bolt is a high temperature resistant fastening part for ISZ520 52 heavy-duty diesel engine exhaust manifold assembly. It fastens exhaust manifold tightly on cylinder head to keep sealing interface compressed, avoiding exhaust gas escaping from joints under high heat and engine vibration. This aftermarket replacement bolt solves bolt stretching, thread failure and fracture hazards caused by repeated thermal cycling and long-term heavy load fatigue of original fasteners, eliminating exhaust leakage and protecting nearby engine components for long-distance heavy cargo transport vehicles.
Product Advantages Adopts alloy steel with professional heat treatment process, featuring excellent tensile strength and anti-fatigue performance. Precision rolled threads guarantee even stress distribution and stable clamping force. Surface anti-oxidation treatment reduces high temperature oxidation and rusting. Each bolt undergoes mechanical performance sampling test before shipment, reliable fastening capability and convenient for exhaust manifold overhaul.

FAQ
Q1: What troubles will broken exhaust manifold bolt cause?
A1: Exhaust leakage, hissing noise at manifold joint, soot accumulation and engine power decline.
Q2: Why replace all manifold bolts as a set during maintenance?
A2: Old bolts have hidden fatigue damage, replacing all together ensures balanced clamping pressure.
Q3: What risk exists when over-tightening the manifold bolt?
A3: Excessive torque may crack bolt or deform exhaust manifold sealing surface.
Q4: What can accelerate bolt thermal fatigue?
A4: Continuous drastic temperature change plus constant chassis vibration will shorten bolt service life.
