steering pump

I am full of questions and here is the next one.
Just few days ago I had checked the oil level when starting up the engine I saw the steering pump that is moved by the rubber transmission belt start and stop. I try to explain better, there is like a clutch inside the disk moved by the belt, it looks like this clutch deactivate the steering pump blocking the disk when no power steering is necessary. Could it be?

Great Tony,

this is the part I mean

tks

Giancarlo

how can I attach photo like you do?

Don't worry about my name! You did not hurt me at all and my wife colleague is from Spain Tarragona very close to Barcellona she is very cool and simpatico she calls me also Gianni so it would be typical from your area call me Gianni

Well I don't thing to get the right size of the picture like your, I hope you will be able to recognize the part I mean, the left high side of the engine.

I am happy too and first of all lucky to meet an expert like you!

Did have some repair on your 2.5, or some advise for use and maintenance?

You're talking about where you made the arrow?

From what I understand, that's the viscous heater. It helps the engine warm up faster by heating up the coolant which gives heat to the driver and passengers MUCH faster. Very effective.

Thank you Marlon!

But is it normal that this unit starts and stops itself sometimes?

Yes.

In the cold, without that heater, You'd be waiting forever for some heat in the cold weather. Ever driven a diesel without that pump?

Forever is actually an understatement...

It actually has a mechanism inside it that churns a separate, highly viscous fluid. That fluid gets so hot that the coolant passing through the pump housing gets warm too.

No before the KJ I drove just one diesel car VW lupo TDI a very little city car I didn't recognize this heater. The Lupo engine warmed up within 15 kms (10 miles approx) but now I admit that the Kj engine is real faster warm that the VW some minutes!
I have a privete pilot license the are airplane where the water pump does not start until the right temperature has not been reached then the bulb activates the pump.

Men you are better than the Jeep "technician" he told me that this was the steering pump (blarg)
I was lucky to meet you all everybody expert and first of all kind and simpatico

those are the first pictures of my KJ

It is ok to know your car but that you know more than a technician from Jeep? That is worrisome! How can I trust them the next time I will go for a maintenance check?

Yeah well, we all know how good JEEP 'mechanics' are...

I searched my manual but it seems to be missing the heating / airco chapter. Thanks for posting that link, now I know what it does. I might see it work someday, when I park my car in the freezer

From that article:' It turns on when the air temperature is below freezing and the engine is below its operating temperature.'

It never gets any colder than 5 degrees Celcius over here.

Giancarlo: nice pics!

And if anybody cares: VW's TDI uses glowplugs in the heater inlet hose.

The exact temperature at which it activates is decided by the vehicle manufacturer. I can hear mine come on below about 45ºF.
