I too have thought about whether to lose the viscous fan or not. I also have air con which I use a lot, as yet I have never known the two electric fans to come on due to the viscous fan's ability to shift the air when required. The only time I got the temp gauge to move above normal was coming back from the South Of France with external temp of 38 degrees and me clogging it up the autoroute.

I think that I will leave well alone for now.

do you know if thermostat wasnt stuck open ,do we know if your exaggerating ,of course a fan will cool rad ,the bigger the fan output the quicker rad will be cooled,thats not the crux ,going read the whole article and similar with open mind ,then you know theories behind what you see

so rather than admit you might be wrong you would rather beleive i was posting a load of bull or am to thick to know if me thermostats stuck..... i had an open mind about you but youve proved to me that a lot of people on here have you sussed.... you got a fair bit of landie knowledge but are an arse when somebody dissagrees with your eggspurt opinion.
ive no doubt youll have to have the last word but i aint going to waste my time responding to you again on this thread.

If you were to come to me and give your description my first assumption would be thermostat stuck open it's the classic symptom! I'm afraid your having a go at a lot of mechanics out there that would agree with James Martin, I very much doubt blowing air onto an engine block would have much affect at all I'd be looking at the thermostat all day long. They can be intermittent you know, just do it once in a while until they pack up! You can tell me I'm an arse too, I only do it for a living! Oh, and I worked on French **** for a while! Hated every minute of it!!!!!
 
check the thermostat - its cheaper than an engine or hgf. James n I might disagree about the merits/demerits of electrical fans, but one thing is for sure - kiss - try the thermostat first.

you made the accusation that the blokes article must be wrong based on an assumption youd made,i only pointed out he wasnt and why,most would see logic in how the system works ,i do make mistakes and will own up when i do ,but im not going to post wrong information to suit your ego :rolleyes:
 
in the face of the overwhelming body of expert opinion i guess ill just have to accept that i had an extreemly clever thermostat that worked perfectly for years but stuck open every time the leccy cooling fan was turned on

must put me hard hat on before i go out.... ive heard pig crap on the head might hurt
 
Hang on there fella. We ain't said it is deffo that ( we aren't there)...... Just that it is an easy and cheap check to make.

It could be the power surge when switching the fans on, screws up the voltage regulator to the temp gauge :rolleyes:.

Yu asked for our help, but we can only go on the info you tell us.
We ain't mind readers or wizards.
 
Snap on don't sell crystal balls. But if three people agree on the most likely cause from info given I don't see what the problem is. You wanted opinions you got three all the same. I don't know the other two guys but from their posts they're both very knowledgeable. People have called me that too on occasion. I would suggest paying someone for an opinion cos free ones are obviously crap! :)

get off yer high horse... i didnt ask for any help.... i just presented what evidence i had to suggest that a leccy fan could cool an engines water below the thermostat opening temp.. jm chose to tell me it was immpossible so either me stat was broke or i was bull****ting... without any evidence for either and wont accept he could be wrong.

for what its worth over the years ive done the same mod to several cars with leccy fans with the same results. ive no reason to think that any of them had faulty thermostats.
 
Why oh why does it have to rain the week i decided to store my new engine outside. I also need to take the fan off that badboy so it doesn't foul on the steering box.

before you start calling me ,youd better go and read up what thermostats do and why ,and how if closed below opening temp it doesnt matter how big your fan is :rolleyes:

If you drain the coolant. Take the stat out. Put a big funnel on the top hose. A really big fan may cool it sooo much it turns inside out:)
 
a few simple questions'

why fit a radiator muff to a series or defender in the winter? if the thermostats shut it cant possible do anything...... oh unless its to stop airflow cooling the block.


what happens when you turn your hot engine off..?.... water stops circulating...... is the engine still hot when you come back two hours later..... hell no heat has dissipated from the block to the surrounding air

ever seen a deutze air cooled diesel in a combine harvester.?..... cant possibly work its got no cooling water......


why will the eggspurts not accept the possibility that blowing air over an engine block will cool it.?



bye thats my final post on this subject.

The muff is to help the engine heat up faster so it gets up to temperature rather than driving round with it stone cold for longer it also means theres more heat to try and heat the cab.

When the engine is off the thermostat is still open so water can still slowly circulate until the thermostat is shut. The radiator is dissipating most most of the heat.

As to the heat moving into the air no one is arguing that heat radiation and dissipation doesn't happen you're just being a useless, pedantic, arse!
