The 80 Series 1FZ oil cooler is often ignored unless its an engine rebuild. But the sad news is the oil cooler an be jammed up with gunk or even be a source of an oil or coolant leak. The location of the oil cooler isn't in a great location and requires removing the exhaust manifolds for the best access. With the oil cooler and cover off you can generally clean those up and don't require replacing. This kit takes care of all of the gaskets, crush washers, and plugs on the cooler.
