Vehicles affected; all Patrols with plastic engine fan, which is all GQ and GU.
The engine driven cooling fan on Patrols is made of plastic (apart from the steel hub that bolts to the viscous clutch hub, and over time, the plastic becomes brittle and cracks as shown in these photos.
Once these cracks start appearing, there is a risk that the fan may shatter and fly apart, possibly damaging the radiator, drive belts, or any thing else in the area.
The good news is that new fan blades are relatively cheap (on ebay for around $100), and an easy DIY job with basic hand tools.
There are few different models of blades used across the Patrol range, so when ordering, you will need to know number of blades (7 or 8), and the bolt spacing where the blade hub bolt to the viscous clutch.
