When you get one of the 2.5L Nissan’s mentioned in this video up on the lift you may initially notice that it looks like oil is leaking from the spot where the oil cooler is mounted to the block. While this may be the case, more often than not it is an internal gasket leak. For your repair, it’s actually easier and recommended that you remove the entire cooler from the block and replace all of the gaskets at this time. Because of this, we’ve developed a Nissan oil cooler gasket kit (pat # 01204500) that includes both gaskets you’ll need for the repair.
