Oil or Coolent Temp

I've got a trans. temp on my pillar and it usually barley moves (I've have a manual). I have been wondering if I could relocate the sensor to either monitor the coolent temp or possibly the oil or engine temp. I think the sensor is a 1/8 NPT thread, could this be used for this? Or do I need a special adapter of some sort?

It is the same temperature sender I think. Another option is to buy another sender, and get a switch from radio shack, and you can monitor BOTH temperatures, trans oil and coolant with the same gauge. I have a 3rd sender on the way so I can monitor coolant temperature, vegetable oil temperature AND oil temperature with my single Cyberdyne digital gauge

Where is a good location to put the sensor so I could monitor the coolant or oil (pics would be great). I've got an extra sensor so I could get a switch and monitor both. Thanks for the help Kirk!

I monitor oil temp and was thinking about adding coolant, but after watching the EOT, I decided coolant temp monitoring was useless. The PCM uses EOT to determine engine temp so I think it's a better choice. Besides, one won't go up without the other, right?

there are a couple places. I think the best bet is to tee into the OEM sensor's spot on the HPOP reservoir. The other option is down on the oil filter mount.

For me, coolant is heating my alternative fuel (veggie oil) so I like to know that temperature. Plus, it is another switch, light and gauge I can put in the Batmobile!

I am going to put my oil temperature sender in the port on the oil filter head. You can put the coolant temperature sender in a tee in the hose going from the block to the heater core.

Good point Joe. I'll check out the HPOP location.

Yeah, I can see the need for coolant monitoring if you run WVO...

Best place for the coolant sensor is that plug on the driver's side of the water pump. I have a vacuum valve that cuts the coolant flow to my heater core so teeing in there wouldn't work for me.

Joe's right, below the t-stat housing to the driver's side, you'll see a pipe plug facing the 3 o'clock position. Tap your coolant temp sender right there.

ha, ha. the pic isn't my waterpump. Found it on someone's site describing a water pump changeout.

Can't you tee into that port for the coolant filter and the sensor? I was thinking that if I ever invest into a filtration setup, that I could do just that.

You can screw the sensor directly into the port and off you go. That's what I did. I don't have my truck with me today or I would snap a picture of the sensor in there.
