Where do I fit sender unit??????????? • The Dodge Challenger Message Board

Almost finished making a replacement dash for the Challenger which will be kitted out with Autometer gauges.

Thought I'd just check out a location for the temp gauge sender, and there ain't one!!

The stock sender is much smaller than the Autometer unit and the sixpack intake doesn't have any other drilling.

Someone suggested going into the top hose using a purpose made adaptor, but this sounds pretty dodgy to me.

Any thoughts would be appreciated.

There should be a sender located right at the front of the manifold, the size of it shouldnt make any odds. Crimp a new loop terminal onto the Autometer gauge wiring and attach to the old sender.
Is the sender missing all together?
I certainly wouldnt attatch anything to the hoses.

If you have to add a larger sender, I would drill and retap existing location.

On a big block the sender goes into the front of the water pump.

It's a mechanical gauge Dave so the sender is much larger. I've been told the manifold would have to be built up before tapping for the larger fitting.

Maybe the route to go is your initial idea, and go for an electrical gauge using the original sender which was working fine.

I would go the electric guage (same face etc) route.
Surprised the manifold has to be built up, thats why I suggested redrilling original location as it is more built up there, however I dont know if its wide enough to accept your mechanical sender!

I have a mechanical AM gauge on my R/T SE, with an aluminum MP water pump housing. I can't remember exactly how it looks, and I don't have any pics around, but it works. And the (huge) sender is in the stock place.

If you go electrical, the stock sender will most probably not be compatible with the AM gauge (it won't have the same temperature/voltage curve).

Hi zogg

I spoke to Real Steel today, and they reckon the sender for the electric gauge will fit original take off, so that's the route I'm taking.

Apparently the original location is not large enough to drill out for the mechanical unit.

I'm hopeful that the new sender will fit without any mods.

As you say, the original will almost certainly be incompatible.

Thanks guys
