Oil temp sending unit mounting

[BBotham]

I want to install an oil temp gauge and need to know if there is somewhere I can mount the sneding unit without drilling into the pan?

I'm reading oil temp through the "extra" 1/8 npt hole in the oil filter base. My Attitude monitor has the wiring and probe for trans temp, but with my manual I wasn't too concerned. Instead, I plugged it into the filter base.

Thanks BD I will give it a try!

I have a port for one if I ever decide to go that route. Its on top of the filter housing.

That is exactly where I put mine it seems to work great thanks for the help!

Mine has two extra ports. I used one for pressure, one for temp.

Hey AH64ID, I have that exact setup. The problem with mounting the oil temp sending unit that high is it doesn't read anywhere near accurately. Reads very low all the time. I'm planning on changing my configuration at some point.

Tinman - how the heck did you get access to the port that's closest to the block!? It's got a cooling pipe going right over top of it. Can you post a picture?

How low? That seems really odd as thats fresh oil and flowing all the time.

If you really want an accurate reading, like after it has gone thru the block I would pull oil from one of the plugs by the ECM and then dump it back to the pan or the oil fill cap with a "T" in it for the sender.

It usually reads less than 140°F (lowest reading on the gauge).



I've always assumed it's because the sender is transferring heat to the air because it's elevated.

Hmm... That seems very odd. . my filter, which is 6 feet from that "T" gets to be quite hot. . I wonder if you have a sender issue. It's miliseconds from when the oil leaves the filter housing to when it hits the sender, I highly doubt that the sender cools any.

Have you tried putting the sender in hot water to verify its accuracy?

Also do you have a bypass? Or just the sender in the "T"?

I've never tested the sender, I just assumed it was correct.



My plumbing is just like yours - a tee with a branch going to a pressure gauge and the temp sender in the other branch.



BTW, by experiments with a thermocouple I've found that "too hot to touch" is between 135°F and 140°F (depending on your pain tolerance, of course).

Thats why, there is no flow thru the "T" so your just getting radiant heat. If your other branch had a bypass on it, like mine, then you would get accurate heat. You need the temp sender in a flow of oil to read accurately.
