Is there any way to test a viscous fans
Tractor running hot

Unplug whatUnplug it so it runs all the time and see if tractor cools down.
Why does a viscous fan run hard at startup? I would run for a couple of minutes first for the cold comparison.
An increasing number of applications over the last 15 years have been using engine ECU controlled Vistronic units. These are controlled electronically and can have varying degrees of engagement, rather than a simple bi-mettalic strip at the front which senses the heat removed from coolant and is either on or off.Unplug what
Like this?My old Hilux had a viscous fan problem, it wasn't locking when hot, but the valve wasn't seized so I opened it and dumped in a little pot of RC car silicone shock oil.
Sorted....
They do, i thought they might be less reliable, but has turned out not to be the case.I'm pretty sure NH TM's had an electronically controlled fan...
