• Chevrolet Aveo / Kalos / Daewoo Kalos – Fits the 1.4 L engines from 2003 to 2013.
• ZAZ models – Designed for older Soviet‑era vehicles requiring robust cooling hoses.
• Other OEMs – The hose’s universal design allows it to replace original parts in many other brands with similar specifications.

Installation Guidelines

Proper installation ensures optimal performance and longevity. Follow these steps:

1. Preparation: Clean the radiator fittings thoroughly, removing any old gasket material or debris.
2. Gasket Placement: Place a new EPDM gasket on each fitting to create a seal.
3. Hose Attachment: Slide the GAT 3473 hose onto the fitting, ensuring it sits flush against the gasket without twisting.
4. Tightening: Secure the hose with the supplied clamp or screw, tightening to the manufacturer’s torque specifications.
5. Pressure Test: After re‑assembly, perform a pressure test to confirm there are no leaks.

Maintenance Tips

• Inspect hoses annually for signs of wear such as cracks, bulges, or discoloration.
• Replace any hose that shows visible damage immediately to prevent coolant loss.
• Use a compatible coolant mixture (typically 50/50 antifreeze and water) to maintain optimal temperature control.
• Avoid exposing the hose to direct sunlight for extended periods, as UV rays can degrade rubber over time.
