I'm suspecting that the viscous fan coupling on my 19J is on its way out. The temperature gauge has been reading hot for some time, but I believe this to be inaccurate. The needle is normally fairly stable there so the thermostat appears to be doing its job.
With the engine off and cold, the fan can be turned by hand with a bit of resistance, and after a couple of rotations it frees up completely. When the engine is switched off after a run, the fan freewheels for about 2-3 complete turns before coming to a stop. My understanding is that this is normally a bit too loose, but of course the Landy fan could be different. The valve pin attached to the bimetallic coil on the front of the fan can be rotated back and forth with a screwdriver so it's appears to function.
Does this sound like the clutch is failing? If so, where's the best source of a replacement? I'd like to retain the belt-driven fan rather than messing around with an electric one.
Cheers
