Read about the TS6469 temp sender on list and at BDub's site and decided to install. Bought TS6469 at NAPA and installed.
The old temp sender was stamped TS6 on flats where socket grabs it. The new temp sender had no stamping there but was was stamped 415 on flat bottom of temp sender that sticks into water passage.
Anyway the new temp sender seemed to respond a bit quicker and very quickly went up to the halfway mark at idle.
Two things:
1. according to tables published earlier that would seem to be 215 degrees which seems a bit high for just sitting there idling. Note I have new motor with about 1500 miles, recored radiator, etc., does that seem normal?
2. The fan seemed to be spinning but I am not hearing any "roar" that people talk about. Is that normal?

When I was using the TS6469 sender it registered at the center point
of my gauge which should have been about 195 deg as I use a 195 deg
thermostat.
I have a MAC dash now and it has a totally different sender.
Here is something that Chuck Aulgur posted a long time back:
From the comments on the net, sever people are replacing the OEM temp
sending unit with a NAPA sending unit. These NAPA temp sending units
are
not a "high dollar item" and they can be manufactured by several
different vendors, all of which can cause considerable variation in the
resistance reading of these units. They are not much of an improvement
over the OEM sender if you don't calibrate them before you put them on
so
you know what the true temp reading is at the 1/4, 1/2, 3/4, and max
points on your gauge.
It is very easy to calibrate the units, or any other temp gauge. All
you need is a small pan or coffee can, a small heating source (I use a
small single burner camping stove that screws on top of a small propane
canister), and a thermometer that will read up to 250 degrees F( I use
my
wife's cooking thermometer that I verify is reading correctly in boiling
water). Place a board across the engine access opening and locate the
heating unit and pan of cooking oil near where the engine sending unit
is mounted( only do this with the air cleaner on the engine and make you
have no gas leaks around the engine). Use a short length of jumper wire
to connect the sending unit terminal to the wire connector going to your
gauge, and another jumper wire to ground the sending unit to your
engine.
Using a small wire, hang the sender down into the cooking oil. turn on
your ignition and slowly heat up the oil. Record the thermometer
reading
at the 1/4, 1/2, 3/4, and max marks on your dash gauge. You now have
your gauge calibrated. I made a small barograph on a piece of
"sticky-back" paper with a vertical line with four cross marks and I
typed the calibrated temperature values at the 1/4, 1/2, 3/4, and max
marks. I placed this bargraph vertically on the glass in the center of
the gauge cluster where the temp gauge is located (If you have a good
memory you can skip this last task).

They have consolidated the senders so most will start at half point
now, even the T-6 Standard

I have the NAPA sender and a 180 degree thermostat. I find that it runs about 2 needle widths over 1/4 on the original GM gauge. I have never seen it go higher but if it ever does I know I have a problem.

Ken,
how long ago did you purchase the sender?
I think the recent bunch are all made a same plant as there is little
demand for these old parts.
We notice this on brake master cylinders also.

Jim, I have had that sender installed for at least 5 years and maybe longer.

Were finding that the new ones read higher.

Mine definitely reads higher than the original one did. Actually I thought mine was reading high. I thought 180 degrees was suppose to be the 1/4 mark.
