Full details

The Nissens Oil Cooler (91167) is designed for automotive technicians and DIY enthusiasts performing cooling system maintenance on specific Peugeot, Citroën, and Mini vehicles. Its primary benefit is superior heat dissipation through advanced turbulator technology, ensuring the engine oil remains at an optimal operating temperature even under heavy loads.

Extended Product Information

FAQs

Does this kit include the oil filter housing?

Yes, the Nissens 91167 kit is supplied complete with the oil filter housing, gaskets, and seals.

Is this a direct replacement for my vehicle?

The 91167 is a direct-fit replacement for specified Peugeot, Citroën, and Mini models. Always check your OEM part number against the Nissens catalog.

Do I need to replace the coolant when installing this part?

Yes, you must drain the coolant to remove the old cooler, so it is standard practice to refill the system with fresh, manufacturer-approved coolant.

What is the benefit of the 'turbulator' design?

The turbulator breaks up the laminar flow of the oil, forcing more of it to contact the cooler walls, which significantly increases thermal transfer efficiency.

How often should an oil cooler be replaced?

Oil coolers are not typically scheduled maintenance items, but they should be replaced if they leak externally or if the internal matrix becomes clogged.

Troubleshooting

Oil leaking after installation

Verify that all gaskets are properly seated and that the mounting bolts are torqued to the manufacturer's specifications.

Oil and coolant mixing

This may indicate a failure of the internal matrix. Inspect the system for blockages and ensure the cooler was not damaged during assembly.

Engine overheating

Ensure the cooling system has been properly bled of air pockets after installing the new oil cooler.

Pros and Cons

Pros

  • Comprehensive kit includes all necessary gaskets and seals
  • Optimized for high-stress thermal environments
  • Direct fit for specific European vehicle applications
  • Enhanced internal flow design for better cooling

Cons

  • Requires professional-grade tools for proper installation
  • Cooling system must be flushed before installation
  • Compatibility limited to specific PSA and Mini models

Setup, Compatibility & Care

Before starting the installation, ensure the vehicle engine is completely cool. Drain the engine oil and coolant according to the manufacturer's service manual. During setup, use the provided new gaskets to ensure a hermetic seal against the engine block. Compatibility is specific to a range of Peugeot, Citroën, and Mini models; verify your engine code against the manufacturer's fitment list before purchase. For long-term care, ensure that your engine coolant remains clean and free of debris, as contaminants in the coolant can clog the internal channels of the oil cooler and lead to eventual failure.
