OK as back for when the viscous fails not sufficient on there own unless you fit an extra fan as Mark Piercy has done.

Te aircon fans work well on the diesel most modern cars use electric cooling fans. Th car is quieter and warms up quicker in winter plus plenty of work space for belt, water pump or stat replacement etc

The stat should be set so that the fans come on when the temperature rises above normal, so that would be 95/98 I would guess in your case. My diesels run at 95C fans come on at 98/100.
The aircon fans are only suitable as back up to the viscous on the V8 unless you fir an additional fan.

Trouble is on the diesel, by the time the overheat sensor activates the fans it's too late.

Think outside, no box required.
Thats handy..
Unless there is a system leak there should be no problem. With a correctly working cap the boiling point is just over 240 F or 115 C. The overheat circuit is activated at 105 C.
wouldnt like to let my v8 reach 100c i'd want extra fans to come on at 95/6c

Except the sensor seems to be +/- 10%, the one in my car operated nearer 115C than 105C, late enough for it to boil.

The stat I use is adjustable.
With a properly maintained sealed system there should be no problem. If the system is not maintaining pressure then there would be.
nothing wrong with the system, i just dont wish another cracked block
You can tune the adjustable thermostat somewhere near with a dot lazer temperature (thingywhatsitcalled) . I'd rather it came on a little sooner rather than later.
