Oil Temp Sending Unit Location - AVIAID Oil Pan

tkb289 · #1 (**permalink**) 08-28-2011, 10:27 PM

I am running an AVIAID 155-55355 (8) Quart oil pan on my 302 and have a question. If I understand the setup correctly, there are (2) possible places to install the oil temperature gauge sending unit.

- On the front of the pan on the driver's side (the drain plug is on the front of the pan, passenger's side).

- On the upper portion of the sump, on the passenger's side … somewhat in line with the dipstick location.

-- Can either location be used?

-- Is one location better than the other, if so … why?

Thanks guys!

Tim,
If I read the positions correctly, the sensor if fitted on the passenger's side is installed vertically and is closer to the centre of the pan (in the longitudinal direction), while if fitted on the driver's side, it is horizontal and is closer to the bottom of the pan, yes? Does that mean that one could be closer to any sludge buildup?
By that 'bushmans' logic, I'd go with the one on the passenger side.
Cheers,
Glen

Glen,

Good reasoning.

In looking closely, the threaded hole on the front of the pan on the driver's side, sits slightly higher than the drain plug hole ... must be for the 'sludge factor'.

I actually decided to just ask Aviaid, short answer is:

- The hole on front of the pan (driver's side) is for the oil temp sending unit

- The hole in the upper portion of the sump, on the passenger's side is for a dipstick tube.

So there it is!

Yes we use the location on the front of the oil pan which is what they designed it for.

Good luck, Keith

Thanks Keith, that's where I have then sending unit connected ... it looks good!

The bung on the front of the pan is 1/2 Female NPT. The old Stewart Warner adapter is what it was originally used for. The bung on side of the rounded side section is actually intended for a dip stick, but is still positioned low enough to work as a temp sender bung. It is 3/8" female NPT.

PS. The drain plug bung is lower because it needs to drain the oil from the pan. The temp sender bung is higher because it's easier to weld that way. If you change the oil regularly sludge should never be an issue.

As I remember, with the earlier Aviaid pans, most of the times my oil changes were only good for 5 to 6 seconds----However, with the cam driven oil/fuel pump, the changes were quicker and easier---

Miss those old days of going up there to visit with Tom and Rodney and hash ideas--

I have the Aviaid gt40 pan on a 347 and could not get a good consistent reading using the hole on the right front of pan about 1/4 way up. Moved it to one of the ports on the remote filter and works great. This gives me the most accurate reading as oil is headed back into the engine. Love the Aviaid products.
