My C4 goes in on Monday for a manual fan control (amongst other things)
For those who have done this is there a location for the switch that would be optimal?
Obviously near the d/s seat to make it accessible, maybe near the steering column or off to the side near the hood release.
Any suggestions?
I'm also assuming that the cooling system will function as normal with the fan(s) cutting in and out as normal, unless I override with the manual control on.
If the fan control is left on, is the circuit cut by the ignition being shut off, or should it be wired directly to the battery for control when the ignition is off?
Thanks,
Colin.

Yes the fans do come on late (for me) .... and I was hoping for a little manual control.
Sounds to me like a PITA if it generates a code. Have to see what the installer has in mind. Apparently he's done a few of these without issues.
A little beyond being "scared", Joel, No spring chicken any more [smile] -- but the high temps of the C4's are an eye opener for sure and I would prefer more control over that. But not at the expense of 'codes'.
I'll holler after Monday's day at the shop exactly what transpires.
Thanks for the input guys.
Cheers
Colin.
That may be the way to go then, 396 -- and may even be what the installer has in mind.
I'll be checking that out on Monday.
Thanks,

Hi Dave -- your explanation is reassuring and sounds like the job is do-able. As I mentioned b4 the installer has done some C4's b4 and apparently knows what's up......
yes I've cleaned out the debris from in front of the radiator and from in front of the condenser.
There was some but not a lot of buildup like I've read about with other C4's. Airflow at the front is on my list of regular maintenance since cooling is so critical on our cars.
About being a "hybrid" -- Is there an OBD1 code-reader available? I'm used to having a reader available to me but understand that this is an odd circumstance and that code reading is not so straightforward.
I know there's another way of reading codes thru the ALDL and have read about that -- Not done that method b4 and would feel much more comfortable with a reader if one is available.
Thanks, Dave, for taking the time to post -- You've set my mind to rest over this install.
I very much appreciate all the help available here with a very knowledgeable C4 crowd.
You guys are the best.
Cheers,
Colin
Right on 396 -- The stat was one of my first 'mods' -- putting in a 180. I've heard that sometimes these 'stats can malfunction closed which will cause high temps .. I'm wondering what the best way is to check that the stat is functioning properly.
The best time probably would have been b4 its install to watch it open in 180-185* water.
Can you watch the digital temp readout and garner enough info as to whether the stat opens or not?
ON a side note, the more I hear about these LT1 engines the more I realize just how tough they really are, and that they "can take quite a lickin' and still keep tickin'" ...
The higher temps seem to be normal for this engine and not as much of a stressor as I once thought.
You guys have made me much more comfortable with this engine; Now it's time to enjoy it.[smile].

Thanks Anthony -- the job is now done and seems to be ok -- tho it was explained that a code would be set but no CEL. So I'll see how it works out as it is.
Speaking of codes: I'm very interested in obtained a reader. I understand that my '94 is somewhat of a 'bastard' system being somewhere in between OBD1 and OBD2. My installer says there is a shop reader available but I need one that more affordable.
A reader for me would be more convenient that reading these codes thru the ALDL panel.
If anyone has any info on an available reader, I'd appreciate hearing about it.
BTW is my '94 a standard 12 pin connector such as this:
12-pin ALDL connector pinout:
F E D C B A
G H J K L M
Thanks,
Colin.
Yes the PCM can 'see' the MFC but it does not throw a CEL. The PCM stores a 77 and 78 code but that's no biggie.
Love the manual control for when things appear to be getting too warm.
