low temp fan switch - valver

[Greeny.]

I bought a low temp fan switch and want to fit it at the weekend. Havnt had a chance to have a look under the bonnet yet to locate where it fits but could anyone give me a quick fit guide? I have to drain the coolent first i assume? This from the bottom of the rad?

Sorry for my stupidness, im no mechanic

Can be fitted without draining the coolant.



Mat.

why do you want to fit that? waste of time. if your original works, why chagne it for a luke warm heater just as winter is coming.

heater? its a fan switch which comes on a lower temp than the standard!? Are you thinking about the thermostat?

Maybe the thinking is fan comes on at lower temps, water doens't get as hot, doesn't provide as much heat from heaters?

Agree they are a waste though, and will just add extra wear on the fan and stuff. Sort the cooling system out properly and it'll be fine as standard.

No idea if this applies to cars that spend a lot of time on track though

Thats not a valver rad in the picture above is it? the fan switch on my valver is half way up mounted on the side of the rad on the drivers side of the car?

That's where it is on the pic :S

Looks like it shows it facing outwards from the front of the rad in the bottom corner?

Why do you want to make it do that? Who has told you this is better than the stock item?

I just assumed that the fan cutting in at such a high point isnt going to do my headgasket much good long term. Ive never had any cars where the fan cuts in when the temp is so high!

flush the system, then reverse flush it, change the thermostat and expansion cap.

Thats all that needs to be done, this is how Renault designed it to run + sounds to me like a dodgy stat.

I mean its cutting in fine I just thought that it did cut in alittle high up the temp gauge. Around the 3/4 mark but it never goes above after the fan has cut in.

 

[Dan@SJM]

thats fine. lets face it, its lasted 10 odd years like that with out a h/g going!

 

[G_F]

Indeed^^^ , mine run for 11 years without a change (then sold and wrote off), engine taking a besting aswell...

So it's working how it was designed to, just make sure it's in tip top condition don't bother changing things.
