I am planning on adding temp probes for engine coolant and engine oil. I will wire them through my selector switch to the tranny temp gage(100-280*F), which currently has inputs from both differentials along with the tranny.

I have a coolant filter and think that there's enough flow through it to give an accurate reading if I install the probe in place of one of the plugs on the housing that holds the filter. This would allow installation without having to alter anything except changing from a pipe plug to a bushing and running the wire. Does this sound like a reasonable point for the probe?

As far as oil temp, I am not sure yet where I want to locate the probe. I have a ESP pre/post luber system that I will be installing but it has no flow most of the time so placing the probe inline anywhere in that system will not work. The ESP uses a replacement oil drain plug that is like a tee fitting with one side being the suction port for the system and the other used as a normal oil drain point. Once the replacement oil drain plug is installed it is not removed, only the pipe plug off one side is removed to drain oil for normal oil changes. I could drill and tap the replacement oil drain plug to accept the temp probe. Would a probe located at the oil drain plug give an accurate indication?

I am also thinking about a bypass oil filtration system, which would be another likely point to install it. Placing a tee fitting at the filter housing and locating the probe in the side leg would give a fairly accurate reading, wouldn't it?

Anyhow, those are my thoughts on where to place the probes. Any input is of course welcome and appreciated.

 

it's not where to put them it's getting her to bend over thats the trick.





but seriously i would recommend placing the coolant temp probe in the block. theres a plug on the drivers side that you take out and install the sender. as for oil temp the easiest would be to replace the oil filter housing on the top of the motor with a billet design that has a threaded hole ready for the sender built in you can get it from elite diesel

"water temp: the plug for this is little trickier. this is also drivers side rear of engine and mine was a female 8mm hex plug below exhaust mainfold and near freeze plug. be sure you have the correct adapter for the sender as it needs a seperate adapter from what most gauge will give you. you will need autometer part #2268 found here http://autometer.com/cat_accessoriesdetail.aspx?vid=58 that convers your 1/8" npt sender to metric 16x1.5 threads be sure to have the new one ready to go before removing old as it is a lake of coolant"

 

Raptor131: With the billet oil filter cap and the gauge in the cab, how do you remove the cap when it's time for an oil change? Is there a swivel fitting that can be put on the cap?

 

http://www.elitedieseleng.com/engine60.htm I'm looking for the site that had 90 degree connectors. i havent installed mine yet but i did buy the billet fuel and oil filter housing caps

 

Just an update...

I got the Autometer adaptor(part #2268) and installed the temp probe in the block as Raptor131 suggested. It was a fairly easy install and I did spray the plug with PB Blaster a day or so ahead of time just to be sure it wouldn't be trouble.

I poked a small hole through the boot for the tranny shift cable and fished the wire up through it, routing it up under the dash to the terminal strip behind the fuse panel cover. I already had all six inputs to the selector switch wired to the terminal strip so all I had to do was land the incoming wire. I used some small diameter wire loom from the probe to the boot to protect the wire and spade lug on the end.

When I went out after the install was completed, I watched the OEM dash gage and compaired it to the temp gage. When the OEM needle was at the bottom mark(C) the temp gage read about 140*F. At normal operating temp the gage was reading around 185*F. It went up slightly when I was stopped at a light, maybe up to 190*F.

As far as oil temp, I will be getting a bypass filter form Oilguard and installing it in tandem with the ESP luber. I will install a fitting at or near the billet oil filter cap and place the probe there.

Once again, thanks for your help and input guys.

 

I've had my oil temp sender mounted in the top of my oil filter (drilled - tapped original) and in summer, it's fine. Now that cold weather is here I made a trip to upstate NY and engine oil temp never got above 140! The cold air coming under hood is keeping the dang correct temp down below what normal should be...somewhere near engine coolent temp. I think I'm gonna drill, tap and mount mine in the oil tank as soon as I can find someone else that has done it or if someone has a pan off to tell me where so I don't hit something inside when I drill it. I'll have my son braze the bung on at that time.

 

Try here for fittings of every shape size and style...

Bud, that's interesting. Does anyone else have any experience with it located at the filter cap or alternate locations for the oil temp probe to be located?

 

I can't believe that no one else has noticed a lower than normal oil temp in cold weather with a probe in the filter location....
