Thermostat or Muff needed?

<< < (3/5) > >>

Saffy:
My temp gauge was in the normal temp with the weekends laning and road travels.  Rad muff was fully closed (nothing to do with the cold but to stop Plains sludge blocking rad). I didn't have the heater on at all, and was mostly driving around with window open (eberspacher diesel furnace keeps things super toasty).

But I still think it's worth checking your thermostat as it not unheard off for even a new/recent one to be duff. Further maybe strap a sturdy plastic sack to front grill - see what happens as easy experiment. I still wonder what the effect is by blocking the flow through the intercooler along with rad... overfueling if pump is previously tweaked? seems to smoke more *Dunno*.
Wouldn't ditch a working viscious fan myself, not with a tdi but that topic usually starts a flame war (someone will come along with CAPSLOCK on and say they circumnavigated the Sun without a fan fitted and even got 45mpg to boot ;))  Same vain I do not think leccy fan belongs in an all-terrain vehicle. Seen a fair amount of leccy fans failing to start on trucks during laning days because mostly they are rarely used and get cruded up with the terrain, others are just bad installations.

Range Rover Blues:
And leccy fans can't shift anywhere near as much air as a viscous.  The engineers at Kenlowe told me NOT to remove my viscous in favour of twin leccy fans.

Anyhoo, another effect of the cold weather is that the air going into your engine is colder, it should make it more efficient but it also chills the cylinder head.

Well unfortunatel I've noticed that my average mpg has gone from a healthy 31/32 to 27 so I think the engine is struggling as it never warms up properly. I'm convinced the stat must be open so will get one today. Even if it makes no difference at least I will still have a spare :roll:

denviks:
i just had the same on my 300 tdi disco..... i swapped out the stat for a 89 degree one and i now have a nice warm heater again.... so much so i need to turn it down now  :lol:

if you change your stat atleast you should have peace of mind its done

Suvvey:
Well I went to local moto factors today and they didn't have one :roll: Thought I'd try Halford's for a laugh and they did :shock: Only thing is that when I checked it at home it was an 82 degree one rather than 88 and also was missing the sprung flange on the bottom :-k. Bit pee'd off but guess I should off checked before I left, but at least I now had a gasket so decided to did out the old (6 months!) one.
There was a small deposit stuck in the stat but don't think this would of been enough to cause much if any coolant to pass through. Took it inside to test and it seemed fine. Didn't have a thermometer to test it accurately but it seemed to be reluctant to open far even in freshly boiled water.
Any hoo's it's all back together now. Just popped in to have a bite for lunch and then out to give it a test drive so fingers crossed [-o<
