Hi everyone, i have a 2011 3.0 patrol. Have had for a year now but am on first god trip with it. Am from bunbury and have travelled to exmouth, have done quite a bit of 4wding through sand, red bulldust etc. Have only just started getting an almost squeaking sound. Sounds like coming from fan belt area. Have checked fan belt and tension feels ok and have dumped 2 buckets full of fresh water on fan region, thinking maybe bulldust might controbute to noise. The noise took longer to appear but does go away when engine is warm. Any ideas please? Hoping not bad. Thanks
