Description
Materials Used for EPDM Lower Radiator Hose – Old Pride
(Raw Materials in the Production of EPDM Lower Radiator Hose for Carbureted and Injected Old Pride)
This hose is produced in two types: EPDM (high-quality material) and SBR (ordinary material).
-
The fiber used in this hose is from the 600-denier polyester series.
-
The primary effect of this fiber in the hose’s construction is to prevent water leakage and loss, while also providing anti-freeze properties.
Service Life of EPDM Lower Radiator Hose – Old Pride
(Useful Life of EPDM Lower Radiator Hose for Carbureted and Injected Old Pride)
The service life of the lower radiator hose for carbureted and injected Old Pride depends on the raw materials used:
-
If made from EPDM (high-quality material), the expected service life is around 4 years.
-
If made from SBR (ordinary material), the expected service life is about 6 months to 1 year.
Signs of Wear – EPDM Lower Radiator Hose – Old Pride
(How to Detect a Faulty EPDM Lower Radiator Hose – Old Pride)
-
Cracks on the outer surface:
The deeper and more numerous the cracks, the more the hose has become degraded and brittle. The best and most reliable solution is to replace the hose as soon as possible. -
Bulging or uneven swelling:
Visible swelling or bulging on the hose surface is another sign of damage. -
Peeling or “double skin” effect:
This indicates that the hose has poor quality and is rapidly aging.
Consequences of Hose Failure – EPDM Lower Radiator Hose – Old Pride
(Impact of EPDM Lower Radiator Hose Failure – Old Pride)
The most significant impact of a failed lower radiator hose is loss of radiator coolant, which leads to:
-
Overheating of the vehicle’s wiring (wires and connections), potentially causing damage.
-
In severe cases, the loss of coolant may cause the burning of the cylinder head.
-
Another result of hose failure is the transfer of hot coolant inside the vehicle, which can splash hot water onto the driver and passengers.
How to Identify a Good vs. Bad EPDM Lower Radiator Hose – Old Pride
(Identifying a Good vs. Bad EPDM Lower Radiator Hose – Old Pride)
-
If the hose is made from EPDM, it will typically have a smooth, glossy surface.
-
If made from SBR, the hose will have a dull surface, lacking the gloss that EPDM hoses have.
-
A high-quality hose will have no blemishes and will not show signs of the “double skin” effect (separation into layers), indicating poor quality and rapid deterioration.
-
Smell test:
If there is not enough light or time to inspect the hose closely, you can smell it. EPDM hoses usually have a sweet odor.
