Elec Rad fan question

no, you need a thermal switch, not a sender...
 
:doah:Duh...Is that the hole by the water neck that mine is covering? :rolleyes:
Any reason I cant wire them on 100% of the time?Until I get a new one and a hose.
Cant be any worse than the mech fan on 100% , right?
 
ya lost me... you'll need to install one in a water port.. if your FI, you'll have a water temp sensor for the computer in the intake manifold, next to the waterneck that must stay there.. some guys have, or put on waternecks with an npt hole in em to run one.. few other ways to go about it... head, etc...

scratch that, 77? carbed? simple.. ok, you wont have a wts, you more than likely have your temp sender in the intake... you should have another port, with a plug in it, in the ds head, right behind the #1 plug that you can use...
 
Depending on the fan, they can put a pretty good load on your charging system, so no, it's not really a good idea to do. If it's temporary, and the draw isn't too much (dim lights, weak heater blower) then it won't really hurt anything, just wasting power and the fan motors.

Mech fan isn't on all the time if it's clutched. Pretty rare that GM used a non-clutch fan, although they are out there.
 
So look for a plugged hole in the manifold?Its an Edelbrock,so Its
probably different .Theres a plugged hole UNDER the
water neck...LOL.I bet I wind up getting the cheaper
neck thats either angled different or with the hole in it.

Does that help? If not I GUESS I could freeze
my nuts off an go snap a pic.... :eek1:
 
We wired up a Taurus fan to the wagonneer, the stock mech fan couldn't keep it from overheating. But damn does it take away some amps...turn it on and the motor drops 200rpm!
 
looks like they have the temp sender in the head, and it looks like you have a 1/2" npt plug on the front of the intake, under the neck.. perfect... put your thermal switch in the front of the intake where that pipe plug is....

Hey could I get a 90* then I wont have to change the houseing?:laugh:
 
:confused: what housing?

it looks just like a sending unit... on your driverside head, you have a red wire running to your temp sender, it'll be just like that.. except sticking out of the front of the intake.... you may have to put a bushing on the switch to bring it up to the hole size..

or am I missing something here?

what kinda drive is that pipe plug? hex, square?
 
Hang on Ill go take a pic of what Im talking about,then you can tell me if thats it.

EDIT:Forgot my wife drove it to work.....wait for 2 hours then Ill do it.
 
Any way its a hex bolt right under the water neck that im talking about.
That why I asked about a 90*Only about 2 finger can fit under there...
Can It go in the pass head?I can look there too when I go out.
EDIT: here ya go.See the squair bolt hole.can one go there?

you could snake it in there it looks like.. might need to pull the hose to ge it in. and just make sure the switch sits down in far enough that the post of the switch isn't stabbing the hose when it's together..

Thats what Im worried about,Its actually more under the hose than it looks in the pic.Whats the bolt/nut in the back of the head that looks like the check plug in a diff?Above an in the middle of the plugs.
 
thats a water jacket too.. but i would suggest trying that front intake spot, even if that means changing to a different waterneck... I would try it as is first tho..

if all else fails, try the head plug, it may be a real b*tch to get out tho...

Ok I`ll try it 1st.Maybe buy a new one,chrome even ;) angled diffrently.
The head LOOKS easy if the bottom of the header isnt in the way.
Is the temp so diffrent there that it would matter?
Sorry to bug you so much but I want to get it right the 1st time and
not over heat (or under) my motor.
Thanks for all your help too! :bow:
