electric fan

You mean, that BMW fan sucks? 😂

A thermostatic bimetallic spring coil is located on the front face of the viscous fan drive unit. This spring coil reacts to the temperature of the radiator discharge air. It engages the viscous fan drive for higher fan speed if the air temperature from the radiator rises above a certain point. Until additional engine cooling is necessary, the fan will remain at a reduced rpm regardless of engine speed.

Strangely enough none of the cars I have worked on have had this system.
How much heat gets transmitted to the viscous through the pump shaft? May cause a problem with the bimetalic spring engaging point?

Mebbe I am aggressive cause of all the "internet experts" telling me I dont know shit.
By all means prove me wrong and I will be the 1st to admit I was wrong but dont tell me I am wrong because of something that was read which may or may not apply.

LOL - you called me an "internet expert". 😉

i have never claimed to be, but get this - i am not stupid either...

and the explanation i gave was factual, and was backed by experience, which, granted, was not my own. seeing a single car operate is barely experience, i agree with that. anyway, i reckon differences in opinion are good for both knowledge building and creative thinking.

i actually never knew about that coil until searching the topic. i've noticed them before, but never wondered what they were for. i always thought that ambient heat and heat through the shaft (as you mentioned) was the way it worked.

How much power does your viscous fan take to run?? How much power does your alternator take to keep up the voltage when your electric fans are on??

The way I see it is you will probably only gain 1-2kw which is nothing. If you ae looking for that 0.01 sec on the 1/4 mile, buy a faster car!!!

Ill stick with my viscous.

I didn't read all the mombo jumbo, I guess it all makes sence and and and...great!

I did my own electric fan swop with temp sensors and stuff and my car never overheats nothing, my temp guage doesn't even reach the halfway mark on the guege.

In my opnion, just the fact that you have more space to work infront of the enjine is worth it, no matter what gains and what not.

Derek, yes I know your sx as good as mine these days. Which I dont like and you know I dont like it, is the fact that you have to set the idle higher than the norm, since the electric fans mod. I just hope I never have to go that route. But the most important is that you are happy. 8)

That was one of the reasons, if the fans or the lights were put on the idling dipped and went back up but I hate that so that is why I set my idling up, in any case as u say it works for me.

Bwahahahahhahaha It seems he does 😂

VeeCee I never said u were an "internet expert" U do seem somewhat more clued up than the average surfer. However I get it almost every day from some "expert" or another and it really pisses me off.
EG: some twat on meeting me for the 1st time told me flatout that unichips are kak and dont work.

Now I dont know how many he has fitted but I believe its none so I am curious how he arrived at that fact. Thats the kind of character I can strangle.

Hehe, I was there, but I just sat back and watched the show 😛

I would sum this up as my No. 1 Reason to do this mod, if the cooling works properly afterwards, thats a bonus.

true, but what i like about people showing off their dicks is that they all come up with some truths (or sometimes theories) and you can actually derive some good points out of both sides to give you ideas - keep it up gents! (but give the other guy a chance as well - even if its just to laugh at him after you've proven your point)

The only reason why I did this MOD is that my clutch fan seized and had problems with the FWD water pump... That said my conversion hasn't been smooth I had some overheating problems, I think the next step will be to remove the aircon, but i'm not in favor of it.

no problem calibrator. thanks for the compliment! you too broo.

been away for two days and lots to catch up! actually earned some dosh this week!

draco i agree - the space gain was fantastic, but if i didnt believe that the engine was going to benefit, i never would have made the change. i also thought that my unit had siezed (as it was running all the time) but i guess after reading calibrators posts that i might have been wrong.

that said, i really dont have any problems with overheating. once i thought i was having issues, but it turned out to be electrical - and the gauges were not reading properly!

removing the aircon, that helped plenty with cooling. average temps dropped about 10 degrees i reckon.

and yes - its time for a new avatar - this kak new look has made my dudes hairy!!!! hehehehehe. 😈

HAHAHA

sub buddy, gud luck with this hey......

hmmm... interesting first post there, "buddy"!!!

Yeah i didn't think it was too bad Mr veecee......

for the guys with overheating issues I have Redline Water Wetter in stock this reduces the surface tension of the water and improves the heat transfer.

They say up to 20deg F I have seen a 10deg C reduction in a supercharged landcruiser.
