If your Nissan Navara (often confused as “Vauxhall Navara”) is showing signs of engine noise, overheating or oil contamination, it may be time to inspect the timing chain, water pump or oil cooler.

At Pit-Air Motors in Croydon, we specialise in major engine repairs for Navara diesel models, including full timing chain replacement and cooling system work.

Timing Chain Replacement

Navara engines (especially 2.5 dCi and 2.3 dCi) are known for timing chain stretch over time.

Common symptoms:

• Rattling noise on cold start
• Engine management light
• Loss of power
• Poor fuel economy

We replace the full timing chain kit including guides and tensioners, ensuring proper timing alignment and long-term reliability.

Water Pump Replacement

A failing water pump can cause:

• Engine overheating
• Coolant leaks
• Whining noise from the front of the engine

During major engine work, we always recommend inspecting or replacing the water pump to prevent future breakdowns.

Oil Cooler Issues

Oil cooler failure may lead to:

• Oil mixing with coolant
• White smoke
• Sludge in expansion tank
• Overheating

We diagnose and replace faulty oil coolers, flush the cooling system and refill with manufacturer-approved coolant.
