The Shacman X5000 Expansion Tank (Threaded Cap) is an OEM-grade coolant reservoir specifically designed for Shacman X5000 heavy trucks. It maintains proper coolant level, manages thermal expansion, and ensures efficient deaeration of the cooling system. This genuine component features a robust threaded cap for secure sealing and easy maintenance. The assembly includes a single integrated part: the 4011108/Expansion box (threaded cover). This expansion tank delivers reliable performance under extreme temperatures and vibration, preventing engine overheating and cavitation. Below you’ll find a detailed technical description.

Integrated level sensor port (optional) accepts standard reed switch sensor. Plugged with factory seal if not used. Port size M22x1.5.
Total coolant volume: 3.8 liters usable capacity, expansion volume 0.8 liters. Dimensions: 280mm x 210mm x 150mm (LxWxH).
Minimum burst pressure: 3.5 bar, safety factor 2.3. Meets ISO 22166-1 for commercial vehicle cooling components.
Direct Shacman X5000 Expansion Tank (Threaded Cap) replacement for Shacman X5000 models 2015-2026. Also fits X3000 and X6000 with identical mounting points. No software calibration required.
Installation steps: 1) Drain coolant below tank level, 2) Disconnect overflow hose, 3) Remove two M8 bracket bolts, 4) Lift old tank out.
Install Shacman X5000 Expansion Tank (Threaded Cap) new expansion tank: place onto brackets, secure with M8 bolts torque to 25 Nm. Reconnect hoses. Refill coolant.
Threaded cap should be tightened until the grip stops. Do not overtighten; sealing is achieved by rubber gasket compression.
After installation, run engine with cap loose to purge air. Then tighten cap fully. Check for leaks after first heat cycle.
Pressure cycle test: 500,000 cycles from 0 to 1.5 bar at 95°C coolant temperature. Zero leakage or seam failure observed.
Thermal shock: 200 cycles from -40°C (2 hours) to +110°C (2 hours) with rapid transition. No cracks, no loss of sealing force.
Vibration test: 8g RMS, 20-200Hz, 100 hours on three axes. Cap remained tight, no coolant seepage, bracket mounts intact.
UV resistance: 2000 hours accelerated weathering (Xenon arc). Surface gloss reduction <10%, no chalking or embrittlement.
Salt spray: 500 hours ASTM B117 on external surfaces. No corrosion on metal inserts or cap spring. Plastic unchanged.
Inspect Shacman X5000 Expansion Tank (Threaded Cap) expansion tank body monthly for cracks, discoloration, or swelling. Replace immediately if any damage visible.
Check Shacman X5000 Expansion Tank (Threaded Cap) threaded cap seal every 100,000 km. Replace cap if rubber seal shows hardening or deformation. Genuine cap sold separately.
Clean Shacman X5000 Expansion Tank (Threaded Cap) the inside of the tank every 2 years using mild soap solution. Do not use aggressive solvents that may damage plastic.
Pressure test the cooling system annually using a hand pump. Pressure should hold 1.2 bar for 5 minutes without drop.
Replace Shacman X5000 Expansion Tank (Threaded Cap) the complete expansion tank every 800,000 km or 8 years, whichever comes first, to prevent age-related brittleness.
Aftermarket Shacman X5000 Expansion Tank (Threaded Cap) tanks often use recycled polypropylene that becomes brittle in 2 years. Genuine uses virgin PA66+GF30, lasting over 8 years.
Generic threaded caps have inaccurate pressure ratings (often too high or too low). Our cap is calibrated to exact 1.4 bar release.
Counterfeit tanks may lack the internal baffle that prevents air ingestion. Our design includes a deaeration channel for self-purging.
Non-OEM tanks often have poor thread fit, causing cross-threading and cap leakage. Genuine threads are precision molded to DIN spec.
Choosing genuine ensures your engine warranty remains valid and cooling system operates at designed pressure.
Yes, compatible with all ethylene glycol based coolants: conventional green, OAT, HOAT, and Si-OAT. Do not use pure water or propylene glycol.
The cap opens at 1.4 bar (20 PSI) to relieve excess pressure. Vacuum relief opens at -0.3 bar to allow coolant return during cool-down.
Not pre-installed, but the tank has a molded port for adding the OEM level sensor (part number DZ93189777161, sold separately).
Replace every 400,000 km or 4 years. The rubber seal hardens over time, reducing sealing force and pressure retention.
Yes, the mounting brackets and hose connections are identical between X3000 and X5000. Direct fit for both.
Each Shacman X5000 Expansion Tank (Threaded Cap) is individually packed in a foam-secured carton. Includes tank, pre-installed threaded cap, and mounting instruction sheet.
Stock availability: USA (Houston), UAE (Dubai), Germany (Hamburg), Russia (Moscow), China (Xi’an). Lead time 2-4 business days.
Express shipping available for urgent repairs (24-48 hours to most international airports). Minimum order quantity: 1 piece.

For fleet operators, we provide free cooling system health checklists and pressure test procedures.
Symptom: Coolant level drops without visible leak – Check threaded cap seal; replace cap if rubber is hardened. Also inspect overflow hose.
Symptom: Overheating at idle – Possible air pocket. Loosen cap slightly to purge air while engine runs at 2000 rpm for 2 minutes.
Symptom: White residue around cap – Coolant crystallization due to cap seal leak. Replace cap immediately to avoid pressure loss.
Symptom: Cracked tank body – Usually caused by over-tightening of mounting bolts or impact. Replace tank; torque bolts to 25 Nm max.
If the expansion tank appears swollen – Chemical attack from incompatible coolant. Flush system and replace with genuine coolant.
