Help Please

[Bas / NZ]

For those that ran a 3.8 v6 in their Bedford, or those with knowledge, Van has always heated up but the temp gauge has always keeped low, put a new thermosstat in and now the temp gauge is working took van for a run with a mate van ran very hot, opened the bonnet and my made said gee your elec fan is quite, guess what not going, chased the wires and they are tied up under the dash, not even hooked up, does anyone know please where these wire up to as I know the fan switches off and on. /  Also for the NZ guys, do you know where you can get the straight length braded raidiator hose from Thanks Heaps.....

Ok just did a check on Old Holden, seems the ECU controls the fan may have to hook up a man switch or does anyone know how to hook it into the ECU, wire colours etc. Cheers

I'll have a look at mine tomorrow for you

when the fan runs, it runs. if you have your engine cover off you'd feel the breeze at the back of your van

Thanks David that would be great, hooked it up to the battery, gee it's loud, might of hooked it up the wrong way as it was blowing the air out through the radiator very strong.. but cooled it down in a couple of mins....

Also hooked up a pod filter at the front, does your's make a loud sucking sound, I'm trying to make this quiter not louder........

he he you may have gone about it the wrong way bas!

[BusyKiwi]

yeah the pod filters are a lot noiser than standard

did you ever put the timing chain gears in ?

[BusyKiwi]

Had a look at my van, looks like the fan wires goes to a relay in the engine bay fuse/relay unit.
from there I can't work out where it goes (mutlimeter died)

but at a guess I'd say a wire to power (poss ign or fuse box), wire from sensor (or ecu), earth and fan (two wires from fan motor, one is black the other brown)

Thanks David, yes on my fuse / relay box there is a marking Thermo Fan, but it dosen't have a fuse / relay attached to it, guess they forgot to put it in, from there the wires join to the Blue / white wire from the ECU.
Will go with a after market one as they are ajustable. At the moment I hooked it up to a lighted switch and acc so comes on when I start the van, but have the option to switch it off if need be.

As for the pod filter they look good under the bonnet BUT..... May have to mount the VN air box in place where the heater is as I did in the camper. What about those dome type foam ones, do they make the same noise

If you like I can scan the wiring diagram from the Haynes VN Worshop Manual if you think that might help.

Those aftermarket ones can be an arse to seal where the sensor probe is inserted into the waterflow. I had the most luck with a urethane sealant although it is then a sod to remove the hose after it has set.

Have you used Marley spouting for your intake Baz?

Thanks Rougue, pulled a wiring diagram off a link on old holden, the man.. works fine, the fan might be on most of the time for now, but it does get hot inside that engine cover, and can turn it off for motorway use, will take it to an auto elec later on as I have no relay / fuse there at all and also looks like the link up on the ecu is not there either. Yes the after market is hard to seal but I guess worth a try.

Heres a outline fitting it  http://autospeed.com/cms/title_Thermo-Fan-Install/A_2015/article.html

Yes I used 80mm Marley if you want to mount it directly to the throttle body it's a perfect fit, and takes the 77mm pod filter. Just got to paint it Black
