Radiator fans is it on permanently ?
Registration finally arrived today ! Hooray
Took it for a spin as you do !
Is the radiator fan permanently on a very low setting ? I put my ear to the rad and it sounds like its going round though I can't be sure as I thought it was the sound of the engine but it cant be as its to far away !
Obviously on my car I can hear/see it when the fan kicks in !

no..
1st speed is about 87 deg.. secondspeed is 97 or something like that
the rad fan switch decides all that

Even on 1st speed these cooling fans are pretty loud. I can't imagine for one second having to strain to hear if it was on.....are you sure it's not the 'blower motor' inside the cab that you are hearing?

I checked and that and it wasnt the inside blower
just looked at the wiki page and will test it in the morning with a bit of wire

Re: Radiator fans is it on permanently ?
engine running did all the tests and no fan, dropped the spare wheel
checked fuse first on left and that's fine
[
the van isn't over heating but I obviously would want the fan working !
can I connect the fan direct to 12v ? via leisure battery ?
check ground where and how ?
any other checks ?
is a new fan a big job ?

Re: Radiator fans is it on permanently ?
The fan motors are generally reliable so more likely a wiring fault...earth point issues.
Try giving the fan a direct live & earth

That looks like an indicator relay.
No.5 relay is marked "53" top row, 5th from left.

Re: Radiator fans is it on permanently ?
ok so there isnt no.5 relay in...

I take it it should be there for the rad fan to work...and is this the reason I couldnt trigger the fan to work ?
why would it be missing ?

Re: Radiator fans is it on permanently ?
If you have a 2 stage fan that is the 2nd stage relay and the main one is that 70A one above the earth crowns. If you only have a single speed fan no.5 should be the only one that you have. Either way there should be a relay there as I see it. (I would have expected it to be a 2 stage fan as you have 3 pins on the connector)

Re: Radiator fans is it on permanently ?
70A one above the earth crowns
thats not there and doesnt look as if it ever was
so if i get a no.5 relay the fan should work when I do the rad fan test ? (if all wiring is okay...

Re: Radiator fans is it on permanently ?
So long as the wiring hasn't been interfered with you will then have a better chance of getting to the bottom of what is going on. Have you got 2 or 3 wires going into the switch connector? Have you checked for any voltage at that connector?
