Found Temp sender that works with Original Gauge - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**1970 CST Short Wide** · 01-20-2017, 10:30 PM

NAPA Ecklin TS6666 sender works perfect with Original Gauge. You can get the 1/8 pipe adapter for the LS at Speedway.com . We hooked a real time scan to it and ran it for ~1/2 hour.
Sender is at the back of Passenger side head

Am I reading the gauge to be 201* in that position ?

yes, which would be very close to normal for an LS

I am glad someone finally got something simple to work, good job.

I need to give a BIG THANKS to the guy at NAPA who took the time to help me look though his books to come up with this. Wish I could remember his name. Will be going back to say thanks for sure

Would this work on my truck? 1978 C10, gathering parts for my 2002 5.3/4L60e swap.

It depends on what Ohm's your gauge works at. I want to say that in my search I saw an 1/8 pipe sender for a late 70's . All you would need is the metric adapter from Speedway.com. Sorry I don't have the number but shouldn't be hard to find
Good luck

the simplest solution would be to drill & tap the head and use the original sending unit. plus, the gauge would read correctly too.

Why take the chance of messing up drilling and taping. I'm a machinist and would have no problem. This is simply screw it in, most everybody can do that and the gauge IS correct
Just my 2c

If the picture you posted is what you consider "correct" and you're happy, then I suppose that's ok.

YES I consider this correct. This is where the gauge would set with a small block or BB at 180 degrees F. An LS runs at ~210 F so again YES this would be correct
And YES I'm happy, are you?? KIS keep it simple

Thanks for taking the time to come.up with the correct sending unit. Its great to have a bolt in option..

We all know that a drill and tap can make the stock sender fit. I personally didn't want to chance messing up the head.

Especially if you try to do it in the truck. No fuss no muss this way

elf w/capital T · 01-08-2018, 09:32 AM

You are the man! Ive got NVU gauges and trying to find the adapter to use their sender, Your post definitely helped!!

**DaHos** · 05-17-2018, 09:19 AM

Auto Meter 2277 Adapter

Note: I.D. of this adapter where the sender probe will go through is .309 and would require drilling to approximately 5/16" or .312 for a Stewart Warner sender to pass through.

TS6666 WILL NOT CLEAR center bore (Must drill !)

davepl · 05-17-2018, 10:17 AM

FWIW here's a graph of the stock sender. If someone wanted to compare it to this one, that'd be handy data!

Somewhere I have a graph I actually plotted on my own in the kitchen with a thermometer and my own sender...

**Jason Banks** · 05-17-2018, 01:57 PM

I found a pdf of an Eichlin - Engine Management Reference Guide and these are the specs it had listed for the TS6666

TS6666 1 threaded stud
156.6Ω@220°F, 1633.2Ω @100°F
1/8 x 27 Dryseal
