Fascinating really, the dynamics of a cooling system. @RangeRoller dt I did not know the viscous engaged incrementally, that's really interesting.
On the front of a viscous fan ,theres a small spring , looks like a ,wee snail shell ,thats what controls the amount of fluid that enters the drag bit of the fan center ,It expands n contracts opening and closing a valve that controls fan speed depending on air temp ,the fan will never reach 100 percent engine speed ,think max is 80% or it would explode :eek:,,if the thermal spring rusts or rots away no more cooling:eek:... happy Easter all ...

Can’t stand to look at her lately, not her fault. Just worn down I am, was stuck without work in lockdown now I’ve been flat out for months, minute you stop it all hits you.
At least you have money coming in and once you've caught up, you can fire into it with all the enthusiasm needed. I bet if you go and sit in it for just ten minutes you'll be swayed;)
 
Thanks for the description DubbleRR.

Iveco's fitted with the 2.8 engine sometimes have an engine fan that's activated with an electric clutch. That's a very interesting solution; The power of an engine driven fan, with some control over what it does.

Mark Piercy hi, I have a nanocom, I built this plate to support it yesterday, its not painted yet, going to finish it today.

Can I ask how you have your nanocom set to come on please, you have it wired to the key?

Was thinking about adding a switch to the 12V+ line of the obd port, below

its not wired into the car, it was plugged in while the engine was idling so i could set the thermostat controller for the fan.
 
I see. Right. There is an overtemp alarm on the nanocom, I became confused and thought you could trigger a fan with it.

I have a madman EMS3 that can do that. I need to figure out a gauge pod to fit it in.

this where the thermostat sensor is.

and the controller, i dont take the written numbers into account on the controller but use the nanocom when plugged to get the engines sensor reading to set the ideal temperature for the fan to come in.
 
@Mark Piercy
That sensor bulb looks a long way from the actual source temp? also a lot of the bulb out in air.
What temp do you have it set at on the Nanocom?

The last 1 I had was fitted in the top hose, to control a variable speed electric water pump, but thats another story.
Not sure where the "beast" gets it reading to turn on the electric fan, must check 1 day;)

97 on the nano, I can't push the sensor in any further as there is the oil cooler in front of the rad. It works well and has done for 4yrs so far:cool:
 
its an interstinfg solution Mark, I like it more than piercing the hose with one of those lances.

few things today. Im relocating the oil cooler, I have a spares car so busy making a bracket for the spare trans cooler I have.

I finished the nanocom mounting plate, sprayed it with stonechip, hoping it wont chip off.

I'm looking for black leather cheeks for the center console, these ones are cream leather. I might paint them... I painted the seats brown and they came out well.

More relevant to this thread; I took the manifold off my 2001 P38 diesel spares car, to have a look-see at what sensors there are.

There are only two, there is no third sensor on this late model diesel. I stared and stared at it, I can not see another.

I want to add a switch to the ECU sensor that tells the aircon fans to come on over 100°C - I think thats the green connector?

When I'm driving up the mountain, I'll turn the aircon fans on all the time.

The third sensor goes in were there is a blanking plug under number 5 inlet
