Hello fellow LZders. A new development in my Disco 2 TD5 journey.
About a month ago, a routine drive had an interesting turn. A fan (at least that's what I think it is) cut in whilst I was tooling about. I thought it was just the viscous fan cutting in as things got a bit warm. It had never done it before. But, it does it every time I drive since, with the engine cold or up to temperature.
It's really, really noisy. It seems to cut in about 2000rpm and then the pitch just increases, like it's getting faster and faster as the rpm rises. I've checked the coolant and it's fine. The temperature gauge seems to operate normally too and the coolant level is fine too, thought when I checked it after the first few times, it was a bit low - think I may have a leaky core plug.
It only cuts in when I'm actually driving and it I raise the rpm when stationary, it doesn't cut in, so I'm having a hard time actually witnessing it (other than the audible whine as I drive). Everything else seems normal and it doesn't sound like the whistle of the turbo - which is always there in the background, but relatively quiet.
Suffice to say, I don't think it's normal and before I go poking around too much, I thought I would check in and see if anyone has seen this before or any advice on things to check first - such as the right search terms to use to narrow the results on here
Much appreciated!
