Ask them for a Wells part number TU-5. That is the correct sender. The ones on eBay are pretty much all the same incorrectly calibrated "one size fits all" pieces of crap they sell to enthusiasts thinking we will never know the difference. But once you install them and then see your gauge reading 210 when it is actually 170 degrees water temperature, you will get as mad as the rest of us.

The Wells TU5 is the most accurate one I tested other than finding a vintage 1970s Delco sender. Stay away from the newer Delco senders as they are completely inaccurate. See here: http://www.sssacc.org/Tips/Temperature_Sending_Unit.doc.
Or here (where they used my chart!). http://www.camaros.net/forums/showthread.php?p=1486927

It seems like all the modern produced senders other than Wells are made by the same company who has the resistance settings all wrong, leading to the too-high temp gauge syndrome.

The autozone sender is made by Wells; it is part # TU5.

Another one I have had good luck with is sold by CarQuest. It is part # 53-7719.

In my tests both of the above senders were very, very close to the old AC Delco # 1513321.


In a case where you have a laser gun and your gauge still reads 7 to 10 degrees hotter on the dial than actual, (and you have tried one or the other of the 2 above senders) try a Sorensen TSU5.



WARNING: STAY AWAY from both GM #12334869 AND NAPA # TS6469SB. Both of these have low resistance and will cause your dash display to read anywhere from 10 to 20 degrees higher indicated temps than actual. (Verify with a laser gun.)

On ebay, a seller's car fitmet chart says the Wells TU5 won't work on 70s Firebirds with guages. Sure looks like the right part, though.

He's wrong.

Here is my original testing in the old thread. You can see the Wells TU5 was the closest specs to the original, old sending unit.

Steve is correct, I have now tested a TU 5 with a 1970 set of gauges, and a 72, its very close.

I have 3 original ones that look as good as you will find. All have the AC Delco upside down.. ANyone want one just PM me, beats the heck out of a repo one..
