Re: Disco running too cool

Whip out the thermstat and take a look. You may find that it doesn't make much difference running without, in which case, the thermostat is probably stuck open, so replace it, for the sake of a few $.

Mine originally came with an 88 degree thermostat and always ran slightly cool (but not as cool as yours). Now it has an 89 degree thermostat and runs right in the middle. Not sure what the tolerances are though. There is always the possibility that yours is fitted with a cool thermostat due to local market requirements.

Also, is your temp gauge accurate?

Very wrong.

The only time you will get TDi remotely hot is at motor way speeds or towing.

You try and get one to over heat in a traffic jam. You would be surprised how much of the time the thermostat on a tdi remains closed.

You need a fan to be working correctly whether it be electric or manual.

As you rightly said the original posters problem will be a faulty thermostat.

Trust me Andy

Take the fan off one and put it under load on the motorway and see what happens. Less than efficient radiators add to the problem.

More to do with the design of the front of the vehicles I am sure.

Yes you were frank.

But as usual the thread has changed somewhat.

Your problem will be solved by replacing the thermostat.

Or fit a winch and Cibie Super Oscars in front of the grill.. Yours will run about right and mine will be too hot :-)

sounds like a thermostat. viscous fans alway spin a bit; only ever had one that behaves as it's meant to do and just idles when it's not hot, and that's on a V6 sierra; which is a very big fan compared to the average car.

TDis are renowned for running cold and taking ages to heat up though, it might be that your

Crikey Austin, have you been in a time warp or something? The original question was posed a month ago.

yeah, I found it in my outbox. dunno why it never got sent.

Yes, most likely the case, and easy to check/fix.

Ours was exactly the same when we bought it a couple of years back.

My Rangie viscous fan is solid on the shaft but temp still gets up to normal & stays there. Why is a solid fan coupling a problem? (apart from the noise)Didn't all older cars have the fan bolted to the pulley

Dave?

yes. No problem, as such, it's noisier and wastes power when the fan isn't needed - depending on your driving and load and speed and surroundings, this can be anything up to 95% of the time.

Just gone back to a fixed engine fan on the 110, after the electric one burnt out it's motor on a hot day and left me with no fan at all.

Same with my Series Landrover. I guess it's down to how they're designed.
