I'm installing a electrical oil gauge, but I am unsure of where to tap into the motor to get the temp. I'm figuring on dropping the oil pan and drilling a hole into it to put the sending unit. Anyone do a oil temp?

 

The best place would be tapping into the oil pan... Good luck

 

I'm doing an oil cooler incunjunction with the temp gauge. I will be placing the sender in a "T" fitting in the line coming out of the motor. I have to do this because the area behind the oil pan where the pressure switch is already has the SC oil feed line their and soon the oil pressure gauge sender.

 

Idea #1) Leave the pan in place. Drill through slowly and carefully. The idea is to clear away the drill chips several times before you finally drill all the way through. Then, when you punch through, the outpour of engine oil will wash the few remaining chips out.

Idea #2) Leave the pan in place. Use a good epoxy such as JB Weld to fasten the temperature sensor to the exterior of the pan. If you do this the gauge will read a few degrees cooler than the true oil temperature.

 

mine has a hole drilled into the oil pan... it works good for me...

 

what temps do you see?

 

Good ideas!

Do you need to weld put a threaded fitting on the hole you drill or just wrench it in with some sealant gooped around the threads?

 

The answer is provided by the installation instructions of your sending unit. If it calls for a threaded fitting you probably ought to drop the pan for drilling and welding. If you try to do the welding with the pan remaining on the engine you risk starting a fire inside the pan.

There are threaded blind fasteners which are liquid-tight. A blind fastener is one which installs from one side of the work piece without access to the other side. One example is called Rivnuts. I don't know if they come in sizes large enough to accommodate the sending unit. If a suitable blind fastener can be used, a plain round hole will suffice and no welding is needed. The threads are part of the blind fastener.
