I need a new temp sending unit andu the local parts place only stocks a unit listed for a '80 mustang I6 with a gauge, with this work with the stock temp gauge in my '64?
Thanks
Thanks
I don't know, and it may well, but I'd go to another parts place. Any GOOD parts place oughta have a temp sending unit for your car.
What parts stores are there in DC? You can often go to their online sites and look up parts yourself. www.napaonline.com is good.
If they can't find one for a Mustang, look for one for a Falcon or anything else with an inline 6 and a gauge. Ford wasn't silly enough back then to make a unique sender for only one year of one model, engine parts were same/same across all models.

i dont think its model specific, just year specific...
most parts places will ship to you from their online store....or just order from NPD....

Check the size of the one in your engine, and if you can see, there may be a part number stamped on the side somewhere.
I know that in '62, the temp sending unit was smaller diameter, and went into a smaller hole (about 3/8") in the engine. I also know that by '67 Ford has switched to a larger-diameter (about 1/2") hole in the engine, and it looks like '64 was the crossover year - and given Ford's "empty bin" approach to building cars, you could actually have either one, I'll bet.
I just did some online cross-referencing, and came up with 2 different parts according to four different stores, here are their Advance cross-ref numbers.
Early ('63? '64?)/Small Sending unit:
Advance TSU23
Later ('65? on)/Big Sending unit:
Advance TSU28
Look at your sending unit and make sure which one you've got, if it's the early smaller one, it looks like you'll have to order one from somewhere. If it's the later big one, that '65 one Advance shows may be the one, it shows up as '65 to '69 or so.
I just swapped a '68 engine into a '62 car, and used the later sending unit with the earlier gauge. It works just fine, the gauge reads ever so slightly higher than before, but not enough to worry about, so even if you don't find the "right" one, it may well work just fine.
Just for fun, if you can get the partsmonkey to do it, look in their books, they show the different senders and list their resistance values, thread sizes, etc.

yeah, I need one that will fit a '72 engine and work with '64 gauges :roll: the one on the engine now does not work I think it was designed for a idiot light not a gauge.

another question
what is the difference between the sending unit for a car with a tach and one without?
Thanks

I had a 78 sending unit hooked up to a 62 gauge and it worked fine. As was stated the sending unit from the 62 engine was smaller then the hole in the 78 block. I now use a machanical temp gauge as i have changed my entire dash.
--An aftermarket mech gauge is a cheap and accurate alternative if you have trouble finding a small sending unit. And there is usually a bolt or two under the dash to mount a gauge to without even drilling a hole if that is a concern.
--The temp gauge has nothing to do with the tach.
good luck, Dan

Dang it, had all this typed in and then IE6 crashed and lost it all...grr.
Anyway, I went and visited my parts guy and we browsed his books...
* The early/small sending unit for a '62 (which I'm not sure, but I think it's one notch earlier than the '64 one) specs to 11.5 to 13.5 ohms at 220 degrees F.
* The '65 and later unit specs to 15.2 to 19 ohms at 220 degrees F.
* Pretty much all of the sending units associated with Ford part numbers up to around the early 80's had very similar resistance values at 220F.
We couldn't find any specs for resistance at lower temps, anybody know what they'd be?
We're both pretty sure that the resistance is higher at lower temps, and goes down as the engine temp goes up. (Which should mean that my '62 gauge ought to read lower, not higher with a later / higher resistance sending unit. But like I said, the difference is so small that I'm the only one who notices it, so I don't think they're all that different after all.)
I'll bet that if the one Advance has will screw into your block, you'll be fine. (If not, and if you want to adjust your gauge, there are some posts here on how to do it - it's pretty easy once you get in there.)

I'll add to danwagon's comments by saying that I'm looking into directly replacing the Ford fuel and gas gauges with aftermarket ones, since I'm having a hard time finding a fuel gauge with the "reticle" like my originals, and I at least want the gauges to match each other. Plus I'd get better gauges with actual numbers instead of "just to the left of the circle", "right in the middle", and "way to the right side"... :roll:
I don't know about Mustand dashes, but in an early Falcon it looks very straightforward.

Great! Thanks
I have an aftermarket gauge already, thats why I didn't deal whith this when I put the engine in, I just want to guage to work, it doesn't have to be perfectly accurate. I will pick up the sending unit tomorrow. I may adjust it if I find it to be too far off, but i'm not worried about it.
The advance online store lists seperate part #s for cars with & without tach as well as units for lights or gauges + a seperate unit for calif :roll:
