OEM 60352172 – The genuine SANY parts Expansion Plug (also known as core plug or freeze plug) is designed for heavy‑duty engine blocks, cylinder heads, and coolant passages. With reference 60352172, this cup‑type plug provides a permanent seal against coolant leaks, oil migration, and pressure loss. Manufactured from corrosion‑resistant steel, the expansion plug meets SANY’s strict OE tolerances for press‑fit installation. It prevents freeze damage and casting core hole failures in mining trucks, excavators, and wheel loaders. Trust the authentic component to keep your powertrain sealed and reliable.

60352172 Expansion Plug – Precision Engine Sealing for SANY Heavy Machinery
The expansion plug with OEM number 60352172 is a direct‑fit replacement for SANY diesel engines used in Actlon trucks, SY series excavators, and SR drilling rigs. This cup‑type plug is cold‑formed from low‑carbon steel (SAE 1008) and then zinc‑plated for maximum corrosion resistance. When installed, the plug expands radially to create a leak‑proof seal against the casting bore. It withstands coolant pressures up to 1.5 bar and temperature swings from -40°C to 130°C. Every genuine expansion plug is 100% leak‑tested before packaging.
Authentic SANY plugs feature a precise cup depth and flange geometry that matches engine block bores. Unlike aftermarket alternatives that may leak or corrode prematurely, the genuine part eliminates electrolysis and pitting. By using this component during engine overhaul, you prevent sudden coolant loss and overheat conditions. The plug’s smooth finish also prevents cavitation damage around water jacket ports.
Leak‑Proof Seal
Radial expansion design ensures zero coolant or oil bypass under extreme thermal cycling.
Corrosion Protected
Zinc trivalent coating (480h salt spray) prevents rust formation inside water jackets.
Freeze Damage Protection
Designed to withstand expansion of freezing coolant without cracking the engine block.
Precision Fit
Diameter tolerance ±0.02 mm ensures correct interference fit without distortion.

Why Genuine SANY Expansion Plug Is Critical for Engine Health
Aftermarket expansion plugs often use thinner steel or poor plating, leading to pinhole leaks within months. The genuine plug is manufactured with a controlled cup depth and radiused edge that seats perfectly into SANY engine castings. Its zinc‑trivalent coating provides sacrificial protection even if scratched. This prevents electrolytic corrosion between the plug and the aluminum block (common in SANY D12 and D13 engines).
Using the correct component during overhaul or repair eliminates the risk of plug blow‑out due to improper interference. SANY’s quality control includes a 100% dimensional scan and a hydraulic burst test. Fleet operators report that genuine plugs last the full engine life (over 15,000 hours) without seepage. For critical applications like mining dump trucks or concrete pump trucks, non‑genuine plugs can cause catastrophic coolant loss and engine seizure.

Proper Installation of Expansion Plug – Step by Step
Before installing the expansion plug, thoroughly clean the bore using a wire brush and degreaser. Remove all old sealant, rust, or burrs. The bore must be dry and free of oil. Apply a thin bead of anaerobic sealant (e.g., Loctite 638) around the outside of the plug just below the flange. Using a properly sized driver tool, press the plug squarely into the bore until the flange contacts the casting surface. Do not use a hammer directly on the plug – always use a flat driver that supports the outer rim.
After installation, the plug should be flush or slightly recessed (max 0.5 mm). For engines with high vibration (mining trucks), SANY recommends staking the plug edge at three points using a punch. Allow the sealant to cure for 4 hours before filling coolant. Pressure test the cooling system to 1.2 bar and inspect for any leakage around the plug. If leakage is detected, replace the plug – do not attempt to re‑seat a used expansion plug. Always keep spare genuine plugs in your maintenance kit.
