Application：Air guide shroud between cooling fan and radiator for wheel loader cooling system

• High-strength glass fiber reinforced plastic material, good toughness, not easy to crack under vibration and temperature alternating change.
• Integral injection molding structure, stable size, effectively avoid air leakage between fan and radiator core.
• Built-in closed-cell sponge sealing strip, excellent sealing performance, block air short-circuit and improve cooling efficiency obviously.
• Optimized airflow channel design, reduce wind resistance, the fan consumes less power and saves fuel consumption.
• OEM standard outline dimension and hole layout, completely match original vehicle installation position, easy to install and replace.
• Lightweight composite material, light weight, will not add extra load to fan assembly.
• Good temperature aging resistance, long service life under repeated high and low temperature cycle working condition.

FAQ 

Q1：What signs indicate the air guide shroud needs replacement?
A1：Shroud crack, sponge sealing strip aging falling off, serious deformation, mounting lug broken, obvious air leakage and engine frequent overheating.

Q2：What should be noted during shroud installation?
A2：Clean radiator and fan assembly before installation. Check sponge sealing strip integrity, align mounting holes and tighten bolts evenly.

Q3：What are the common causes of shroud damage?
A3：Long-term thermal aging; fan blade friction impact; installation bolt uneven tightening; hard foreign objects scratch and crack the shroud.

Q4：Can cracked shroud be bonded and reused?
A4：Not recommended. After cracking, structural strength declines sharply. Vibration will expand the crack rapidly, affect cooling performance, better to replace new shroud directly.

Q5：How to inspect shroud in daily maintenance?
A5：Check shroud surface for cracks and sealing sponge aging when checking cooling system, observe whether engine temperature rises abnormally during heavy load operation.

Q6：What trouble will failed shroud bring?
A6：Hot air recirculation and air leakage, radiator heat dissipation drops sharply. Engine temperature rises quickly under heavy load, easy to cause engine overheating and scuffing failure.
