I=E2=80=99m in NorCal. We have a rainy season (usually), lasting from =
November to April. I usually put the hardtop on at the first heavy rain, =
and leave it on through March, depending on the state of drought.
Anyway, I just took the car for a short spin to get it warmed up. When I =
judged it was at operating temperature, the needle had stalled at about =
150=C2=BA. The IR gun read the thermostat housing temp at 180=C2=BA =
(makes sense =E2=80=94 it's a 180=C2=BA thermostat) and the upper =
radiator temp at 177=C2=BA, so I pulled the glass off the gauge and =
reset the needle to 180. I=E2=80=99m guessing that the motor wasn=E2=80=99=
t fully cooled down yesterday afternoon when I set the needle at the =
rest point.
I=E2=80=99ll check it in a few hours and see what it has gone down to.
Someone suggested the needle had slipped. That seems to match most of =
the observed facts, but it=E2=80=99s hard to see how that might have =
occurred, given that the needle was attached firmly when I went to reset =
it. I am theorizing that when the temperature exceeded the intended =
travel, the coil slipped a gear tooth, which is why I have had to move =
the needle to correct the range of travel. Anyway, this approach seems =
very promising so far.
For now, I am leaving the gauge half out of the dash. so I can easily =
remove the bezel.

would have picked me up in a timely manner. But since I had reported =
myself =E2=80=9Csafe=E2=80=9D and off the highway, it took 4 hours to =
get a tow. </div><div class=3D""><br class=3D""></div><div =
class=3D"">2. Check your lifters every so often. I had replaced the cam =
and lifters due to lifter spalling sometime between 1998 and 2010. The =
new lifters were just starting to pit in 2018.</div><div class=3D""><br =
class=3D""></div>3. If you have a yellow plastic 7-bladed fan from Moss =

suppose if it hasn=E2=80=99t broken so far, it probably doesn=E2=80=99t =
have air bubbles in a critical location. But they had perhaps a dozen =
reported incidents. The current product being sold as part #434-332 is a =
