Water temp sender

[JonnyT]

Does anyone know where the temperature sender unit goes on the Ford 351W engine? If they do, do you know what the thread size for the adapter is?

Thanks.

Hi Jon, It can go in the intake manifold or in certain types of thermostat housing,if you have opening above the main pipe.

If you have an Edlebrock manifold it will be a NPT fitting here's a chart to identify the size as these fittings a complicated to measure

American pipe thread NPT (conical)

• NPT Fitting.... Thread-Ø mm
• 1/8"NPT ..............10.2
• 1/4"NPT ..............13.7
• 3/8"NPT ..............17.1
• 1/2"NPT ..............21.3
• 3/4"NPT ..............26.6
• 1"NPT .................33.4
• 1 1/4"NPT ...........42.1

On the edelbrock manifold its behind the thermostat housing, NPT as Rich says

Thanks AK.

We have the edelbrock performer manifold. I had a look last night and couldn't see where the sender could go. The only possible place seems to be a plug on the offside, just behind the carb. However, that seems to go into one of the inlet chambers rather than a water jacket. Any ideas??

cheers

Steve,

is it possible that the take off for the water heater has been put in the water temp sender hole? There is a pipe tail, in pretty much the position that you suggest.

[rich]

There should be another plug/hole across from the heater take off,
as you say the one at the rear is for your servo vacuum.
If you still cant find it I'll try and get a piccy.

See Pic hope this helps?

Heres a piccy, I had to move the coil on my Engine Factory supplied 351 to get to the plug

[dingocooke]

On my set up thats the heater return, but it doesnt matter which you use really, although near the stat is more useful for temp indication???????

[rich]

well now you have two options, the one that Dingocooke is showing is where my heater return is, where have you returned yours Dingo'?


EDIT
we'll have to stop overlapping these posts, its getting confusing
