2011 Nissan Pathfinder Radiator: What it does and how to look after it

Based on the Nissan R51 (2011) service manual (Engine Cooling System – CO) and the Nissan parts catalog for the R51 series, the 2011 Nissan Pathfinder is fitted with an engine radiator. Both the VQ40DE 4.0L petrol and YD25DDTi 2.5L diesel variants use an aluminium crossflow radiator with plastic end tanks. On most automatic models, the left tank also houses a transmission fluid cooler. So yes, a radiator is absolutely relevant on a 2011 Pathfinder.

The radiator’s job is simple but critical: it dumps excess engine heat into the airstream so the coolant can return to the block and heads at a safe temperature. Keep it happy and the engine runs at the right operating temp, the cabin heater works properly, and on autos the trans fluid stays in a thermal sweet spot too.

For Aussie and Kiwi owners, stick with the correct coolant and look after the system as a whole. Nissan Long Life Coolant (Blue) premix at 50/50 is typically specified
