First: a public apology from me. I have been tied up, but
intended to call. (And knowing how busy you can be, I was going
to send you a private message asking when it might be most
convenient for you to speak to me this evening.) Please believe
me: no disrespect intended. I know how helpful you have been --
including to me -- in the past.
In the past I have observed that the fans have come on once the
temperature has come up (to around 195). And the gauge has
operated intermittently (a few minutes on, then a few minutes
off, etc.) -- but when it has come on it has registered what
appears to be the correct temperature.
P.S. If you are still willing to talk and think it would likely
be helpful, please let me know privately what specific time I
can call you, either this evening or tomorrow.

I asked you to call me because it's easier to explain
this shit over the phone
But Noooooo you will not call
Soooooo here we go
Ok start the car and warm it up
Wait until the fans come on
If the fans come on and cycle you already know it's not
the temp sensor in the left radiator because that's where it
is
Have an IR gun ready and shoot the upper pipes for both
sides
Record the reading
It should be around 195 no more
If the cockpit gauges read the same you are ok
If not then most likely it's the temp sensor on the
center water manifold under the coolant recovery tank
If it's that it would take around 4 hours to do a good
job
Nothing is easy with the engine in
Ted Rutlands has my old engine and a cockpit gauges as
well as the temp sensor
Its all from my old car so I know it works
A good tech will charge no more the 8 hours because
that's an all day job
On a good day
That's it
Call me next time

Catching up with some month-long issues
after being away for the last 30 days driving around
the country (almost 9,000) miles with two friends --
in their Ford hybrid. (Yeah, would have been a lot
more fun in one of my cars, but they wouldn't have
exactly gotten over 36 MPG.)
Anyway, just before I left my 1992 512TR went to a
local, apparently competent, mechanic for its annual
inspection. Everything was fine -- except for
(according to him) the temperature sending unit, and
(also according to him) the gauge itself. I had
noticed that the last few times I had driven the car
the gauge seemed to read normally, and then stopped
registering at all. On and off, typically for minutes
at a time. Cooling system seemed to be working okay
(fans coming on when temperature reached about 195).
If I understood him correctly, the mechanic wants to
charge me $350 for both (not each) a new "temperature
sending unit" and replacement gauge, plus an
additional $350 labor. They would first replace the
sending unit, and if the gauge then worked properly of
course not replace the latter, but they said that
based on their tests the gauge was not sweeping
correctly.
I am almost undoubtedly one of the least mechanically
knowledgeable people on this list, so please forgive
the possibly naive questions, but:
- if indeed the sending unit is malfunctioning, I
would have guessed that the gauge might well not
also need replacement because it might be
functioning properly, with the erratic readings
solely attributable to the sending unit. So what
are the chances that the sending unit needs
replacement, but not the gauge? (Seems easy
enough to do what they propose and change the
sending unit first and then see if the gauge is
working correctly before also replacing it; and if
the mechanic were one of my regular trusted
mechanics I wouldn't be wary.)
- Assuming, for the moment, that both the sending
unit and gauge require replacement, $350 sounds to
me to possibly be excessive parts cost and labor
cost for replacing just the former (a quick search
shows that a sending unit is apparently available
from Rutlands for about $60 plus shipping), and
possibly even for replacing both. (All Ferrari
Parts seems to sell gauges for $165. http://www.allferrariparts.com/147163.html
)
Any thoughts would be appreciated.
