- Reinforced EPDM molded hose, strong resistance to high temperature, antifreeze corrosion and aging, effectively prevent pipe expansion, bubbling and cracking in long-time high-temperature operation.
- Combined structure of rubber hose and steel hard pipe, rubber hose absorbs frame vibration, reduces stress concentration and cracking risk at connection positions.
- Smooth inner pipe wall, low flow resistance, reduce cooling circuit pressure loss, guarantee stable coolant circulation and improve engine heat dissipation efficiency.
- Complete assembly with hose clamps and sealing rings, one-piece delivery, convenient for on-site maintenance and rapid replacement.
- Reasonable pipeline layout without sharp bends, reduce air accumulation inside the cooling loop, avoid engine local overheating and cavitation corrosion.
- Good ozone and weather resistance, adapt to dusty, humid and high-temperature construction environment, extend pipeline service life.

FAQ 

Q1: Is this water radiator pipeline assembly compatible with both ZL50G and ZL50GL?
A1: Yes. This pipeline assembly is customized for XCMG ZL50G and ZL50GL wheel loaders. Pipe layout, pipe diameter and connector specifications are universal for the two models.

Q2: What are typical symptoms that the water radiator pipeline needs to be replaced?
A2: Coolant leakage at hose connection, hose bulging, cracking and liquid seepage, hard pipe serious rust or deformation, pipeline blockage which leads to continuous high engine water temperature.

Q3: What routine maintenance should be carried out for water radiator pipeline?
A3: Regularly inspect pipeline surface for cracks, swelling and coolant leakage; check tightness of hose clamps; avoid external collision and extrusion of pipeline; regularly replace coolant according to maintenance cycle.

Q4: Is pressure test and leakage inspection carried out before delivery?
A4: Every pipeline assembly will pass hydraulic pressure test and sealing leakage inspection before leaving factory to ensure no leakage under rated working pressure.

Q5: What precautions should be taken during pipeline installation?
A5: Cool the engine completely before disassembly to prevent scalding; clean pipeline inner cavity and radiator water port before installation; replace old sealing rings; adjust hose clamps to proper torque; after installation, run engine and check for leakage.

Q6: What will cause high engine water temperature after replacing the water radiator pipeline?
A6: It may be caused by pipeline blockage, sharp bending of hose, air trapped inside cooling loop, coolant deterioration, water pump failure or radiator blockage.

Q7: Can high-pressure water gun directly wash the water radiator pipeline?
A7: Not recommended. High-pressure water may impact the rubber hose surface and hose clamp joints, accelerate rubber aging. Clean dust with compressed air or wet rag.
