❓ FAQs — Oil Cooler Inlet Hose (55488382)

1. Which vehicles and engines is this hose compatible with?
This inlet hose suits Vauxhall / Opel 2.0 CDTI engines, including models such as the Insignia A, Astra J, and Zafira C. The OEM part number is 55488382 (also referenced as 55566095).

2. What is the function of the oil cooler inlet hose?
This hose carries hot engine oil from the oil pump to the oil cooler. The cooler then helps reduce the oil’s temperature before it circulates back into the engine, maintaining efficient lubrication and avoiding overheating.

3. What are common symptoms of a failing inlet hose?

• Coolant or oil leaks around the hose or oil cooler.

• Engine running hotter than normal due to inefficient oil cooling.

• Visible cracks, brittleness, or signs of damage on the hose.

• Drop in oil pressure or “low oil” warnings (if oil is being lost).

4. Is this part original / OEM, or aftermarket?
The version we offer is aftermarket (meets original manufacturer spec), often used as a direct replacement for the genuine Vauxhall / Opel part 55488382.

5. Is the inlet hose easy to replace?
Replacing this hose typically requires:

1. Draining or partially lowering the oil / cooling system pressure.

2. Locating and removing the old hose (disconnect clamps).

3. Installing the new hose, ensuring all clamps are tight and properly positioned.

4. Checking for leaks and confirming oil cooler operation once the engine is running.

6. Does replacing this hose solve overheating or leak issues?
If overheating or oil leaks are caused by a cracked or degraded inlet hose, then yes — replacing it should resolve those issues. However, if the oil cooler itself is damaged, or other parts of the lubrication system are failing, additional repairs may still be needed.

7. Are there any related parts I should inspect while replacing this?
Yes — it’s a good idea to also check:

• Hose clamps for signs of corrosion or wear

• The oil cooler itself (for damage, corrosion)

• Nearby hoses or pipes (inlet/outlet) for any other leaks

8. Why choose this hose from D2P AutoParts?

• Built to OEM-spec for correct fit and long life

• Reliable performance under high-temperature conditions

• Cost-effective compared to dealer-only parts

9. Do you supply a warranty with this product?
Yes – we provide a standard parts warranty (check our warranty terms), so you can purchase with confidence.
