Decided to check that radiator fan was working ok so went for drive
till reached normal running temp about 87 on temperature gauge ... returned home
and sat with engine ticking over ... after about half an hour the most the needle had gone
to was about 91 not enough i think for fan to kick in .. how long do you have to sit there till it does..
did pop the bonnet and put head over engine to see if it was excessively hot but no felt normal
its a 2.0 hdi.. also how do you remove multi function display to chang a bulb.... cheers

My petrol's fan comes on at about 95 and turns off at 90.

As for removing the MFD to refit a bulb, just lever it out from the sides - it's that simple

I have NEVER EVER had my fans running due to high coolant temps.

The HDi just doesn't get hot when ticking over, in fact the temperature drops if anything.

Maybe on a very hot day after a brisk run you pull over and sit there for a few minutes it might bring the fan on.

I remember on my 2.1 D8, I changed the coolant and the haynes manual says you should then wait, on high tickover, until the fan comes on. I waited for about an hour with the car in a garage (back end poking out obviously). The fan never came on. It wasn't the warmest of days, but still proves how good the cooling system is, the needle didn't budge hardly anything over 90.

cheers for that guy's thats settled my mind for me

That's interesting because I tried to get the fan working on my HDI 110. Drove it really hard and sat with the engine running at 2000 rpm for 15 mins and the gauge never went over 90 and the fan didn't kick in.
The fan does come on when I put the air con on so I know it does work.
All of this followed my recent problem (see previous post) of coolant loss.
In the end I removed the stat, drove for 200 miles without coolant loss.
Replaced the brand new genuine Peugeot stat and within 30 miles the low coolant light was on. Checked the stat in hot water alongside another one that I had taken out of the TVR and the Pug one didn't open until much later, until the water was boiling.
Replaced with a new one from Halfords, so far done over 500 miles with no problems. and got my money back from the Peugeot dealer
As I'm driving the thing to the south of France in a week or so its quite reasuring to know that my fan may after all, be normal

*lowers bottom lip and wonders off*

Damn you lot, that must be nice not having that to worry about.

Last summer every time i got stuck in traffic i would always get a "Beep" then on the display it would say ENGINE TEMP TOO HOT before the fan kicks in. Pretty scary when sat on the motorway with nowhere to go.

Roll on summer.....

Well i'll go along with what Welton says mine just wont go pst 90...
and i hope you are still counting those pulley's Welton

my HDI never goes past 90 either. I just sit in traffic worrying about the DMF which seams to be on its way (and the repair bill)

I have to say that my 406 is the ONLY car I have driven where I genuinely anticipate major failure on every journey, morning and night.

I anticipate a big *bang* at any moment*

I even drive in complete silence so as to detect any strange noises.



*this fear passes after 30 mins of driving normally.

this is what happens when you buy a D9 welly

If I am stuck in traffic for more than 15 mins, my needle will creep over to 95 ish and the fans kick in....
