Description

Material of the Short Heater Hose for Peugeot 405 (Peugeot 405 Saipa Short Heater Hose)

The Peugeot 405 short heater hose is manufactured using two types of raw materials: EPDM, known for its superior quality, and SBR, considered a more standard material.

Additionally, the reinforcing thread used in this hose is 600-series polyester yarn.

This yarn plays a crucial role in the structure of the hose by:

Preventing water leakage
Reducing coolant loss, and
Enhancing antifreeze performance of the hose.

Service Life of the Short Heater Hose for Peugeot 405

The lifespan of the Peugeot 405 short heater hose largely depends on the type of material used:

If manufactured with EPDM, the hose can typically last around 4 years.
If made with SBR, the lifespan is shorter—about 6 months to 1 year.

Signs of Wear or Failure in the Short Heater Hose for Peugeot 405

Key indicators of hose damage include:

Surface Cracks: Visible cracks on the exterior of the hose. The deeper and more numerous the cracks, the more brittle the hose is, indicating an urgent need for replacement.
Swelling or Bulging: Irregular bulges on the hose surface suggest weakening of the material.
Peeling or “Two-layering”: This is when the hose appears flaky or layered, a common sign of low-quality rubber breakdown.

Consequences of a Faulty Short Heater Hose for Peugeot 405

Water Leakage into the Cabin: One of the most noticeable effects is water seeping into the car’s interior, especially under the driver’s feet.
Coolant Loss from Radiator: Leads to reduced coolant levels, which poses a serious risk to the engine.

At the very least, this may cause the engine to overheat, commonly referred to as the engine boiling over.

How to Identify a Good vs. Bad Short Heater Hose for Peugeot 405

Surface Finish: Hoses made with EPDM typically have a smooth and glossy finish. In contrast, SBR-made hoses tend to have a dull and rougher surface.
Surface Quality: High-quality EPDM hoses are free from surface pitting and do not show signs of layering (also known as “two-skin”).
Smell Test: For those unable to properly inspect the product under good lighting conditions, the smell can be an indicator. Quality EPDM hoses usually emit a sweet rubber scent, whereas SBR hoses lack this characteristic.
