Hi
Anybody running a 3.5v8 tell me roughly where their temperature gauge sits during normal on road jorneys, Mine was sitting at abouth half way, but after taking of the viscous fan it now sits at about 3/4 and the fan doesn't seem to be running as fast lost the jet engine sound when you first start her up.
Look forward tyo hearing from you

Still have my viscous fan, and know it works as I only hear it after a slog up a v big local hill. My temp gauge sits just below halfway (by about a needle width) under virtually all circumstances, except when gunned up a hill that has the auto box hunting between 1st and 2nd under full power....... by the top, the needle drifts just above halfway and the fan cuts in.......... then it sounds like an aircraft for 30 seconds to a minute before the needle falls to just below halfway again.
The only anomaly with mine is that I must have a slow opening stat because on initial warm up my needle drifts to just above half before falling to the usual spot.
Is it possible you have an airlock, or maybe a well clogged rad??
Hope that helps

This time of year mine runs between 1/4 and 1/2 under steady driving conditions, I have two 13" pacet electric fans which cut in just under 3/4 (also have a manual overide switch for wading)
In warmer times it sits half way , But in the winter it runs 1/4
It had a brandnew rad approx 5 months ago
Hope this helps ???

Mine sits at 1/2 way during winter & summer, it rises to about 3/4 when towing the caravan up a large hill but quickly falls back to 1/2 when on level ground.

Mine is a 3.9 on lpg.
Stays @ just below midway only goes over that when going uphills or when off road sometimes, although the aircon fans are normally running alot more than I would like. Which is on my todo list to sort out.
Cheers

Mine sits just under the half way mark on petrol and just on the half way with lpg. it does go up slightly when i gun it on the motorway but never reaches the 3/4 mark. and still on vicous fan

Ok
Thanks for the replies,
So any suggestions as to why mine is getting so hot, have cleaned out the Radiator and checked water levels
any ideas,
Steve

My 101 used to sit on half way, even driving through the desert in 48deg heat weighing 5 tonnes. I gather the viscous fan's more meaty; 101 owners with Kenlowes have had problems with keeping the heat down.

There are many reasons why a V8 will run warm.
But...
Re-reading your first post. If you have removed the viscous fan and refitted it and you do not have the noise then I think you need to check it is working.
When it is cold ie.. in the morning open the bonnet and spin the fan, it should turn easily. Run the engine until warm turn it off and then turn it again there should be considerable resistance now as the viscous coupling should have engaged. At least that's the theory.
If there is no / little difference then either it hasn't been put back right. Or it is borked :( and is probably the reason for the high temps.
If there is more resistance then we can rule out the fan and list other things to check / try!

Actually when you first start the car the fan should be a bit stiff, all the fluid runs out into the vanes and locks the hub up.
As it spins the oil is firced into the reservoir and the fan then idles. When it gets warm the valve opens and allows the fluid back into the vanes, locking the fan up.
So you should hear it at startup and you should hear it when things get hot. All other times I would expect it to sit halfway, that's what your thermostat is for!
Having had problems with the LSE overheating I spoke to Kenlowe. They advised that as I tow 2 tonnes regulary that I shoulkd NOT remove the viscous in preferance to twin electrics as they DON'T move anywhere near as much air.
I have replaced the rad last night, the viscous (though if anything the new one seems to slip even more), fitted a Kenlowe auto box cooler, hosed out the airconn rad and added some water wetter, just for good measure.
I'll let you know how I get on.
