Since my engine was down to bare block, the temp sending unit was replaced. Now my temp gauge reads around 220* but my thermostat housing is at 185* according to my temp laser. Do I keep replacing it with different ones til I find one that's right for my gauge? Anybody got any suggestions?

'Lectric Limited has the correct one.

Never heard of them, this place rocks

Just ordered one. Thanks, brother

hope yours works better than mine. I never did find one that was close to the OEM unit, but this one was the best I could find.

I bought a external gauge and mounted it under the hood of the car as a double check. This gauge reads properly , but at least I know where the in dash gauge reads when properly running.

The in dash gauge reads about 15 degree's colder than the actual temp.

I was so paranoid about my temp gauge being correct that I installed an Auto Meter gauge in the ash tray. The lid still closes to cover it up.

Consider acquiring the Willcox adjustable resistor for your temperature gauge. Works fantastic. Here's my story:

I have tested every sender available... Wells TU5, standard, borg, Gm, and all other aftermarket senders. It is very unlikely that any aftermarket sender will work and even the so called "correct" sender is missing the oil inside (I cut one open)...

The adjustable resistor will solve any issue with any sending unit because it will make a linear change to the non linear gauge... and if it doesn't work perfectly, I'll take it back

Says for 68-76. My car is a 79. Whole different animal?

Any way to wire something inline without having to pull the gauge panel?

Edit: I see this on your site for 79-80. Is it correct?

I was glad I finally did it (and I didn't even need my gauge since my digital indicator already told me my temp, but I'm glad my temp gauge reads correctly )

None of yhe senders work like they should. Some may get lucky and get one close but the best thing is the adjustable resistor carriljc posted.

I have a mr gasket radiator cap with temp gauge on it, a visual under the hood, something to compare to
