The viscous clutch on a viscous fan slips more and more with engine revs. This is because the fan is unnecessary at speed. The forward motion of the car is sufficient.

The fan might be most needed when say towing up a steep hill at low speed.
Hence most decent ones being thermostatically controlled for many a year, rather than one which simply limits the fan speed.

How do you thermostatically control a purely mechanical device?

Via a valve in the viscous coupling.
Such a drive is obvious if you look at it. It has a helical spring on the outside which operates the valve by the temperature of the air passing over it.

The Astra/Zafira only needs the engine supprted while the offside engine mount is removed. Then its jyst a case of removing aircleaner and outer pully that drives alternator and air con and cambelt cover.

Cheap oil is not synthetic. Modern cars run at much higher temperatures than mineral oil can cope with. On old cast-iron lumps it is the wear on things like camshaft lobes that might be more of a problem if you use the wrong oil.

Valve train wear on an old pushrod design is due to the higher loading than an OHC type, and minimised by a suitable additive. Normally ZDDP. Which can be used with mineral or synthetic. It's not a common additive these days as catalytic converters don't like it. But you can buy specialist oils with it, for use in older cars.

Nah. All there is is fluids to check. Brake pads used very little and last 40,000 miles. Ten minutes work.
