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.
