I've only had the car a few days & it's going to take awhile to figure out all the push buttons.
When cycling through I see voltage, RPM's, temp, etc. But I see no oil pressure indication?
Is it there somewhere?
I've been reading sticky's & posts till my brain wants to explode. Loving this forum!
Sorry if this question has been asked a hundred times already.
I'm trying not to be a pest .

Thanks, Brad

No DIC oil pressure readout. The sending switch is an ON/OFF switch on the side of the oil filter adapter. For real-time pressure you would need to fabricate a piping T, hydraulic line, grounded mounting bracket and install the original sender plus an electrical gauge.

Your engine, on 10W-30 oil, hot, should idle at 15 - 20 psi, over 40 at 2,000 rpm. The sending switch is supposed to set the oil pressure warning at about 5 - 6 psi.

You can temporarily hook up a mechanical pressure tester, but it's a difficult royal PITA.

(No, you don't have V03 - engine oil cooler/HD Cooling option)

Well first off, Thank you for your service!
And also thank you for helping a newb Caddy owner.
I have to laugh when I go out to my shop & see my current project. A 1974 Ford LTD. I'm building a hot rod 400 engine and I can literally climb in there & stand next to the engine!! Heh..Heh

The Caddy engine bay makes packed sardine cans seem roomy!!!

Not these. We use 40' of 1 1/4" copper pipe in a double U heat exchanger configuration on the bottom of the boat. The entire engine and manifolds are cooled by 50/50 antifreeze, uses a standard automotive 180 thermostat - and it's all pumped through the copper tubing (think: water cooled "radiator").

Look closely ............... You can barely see the exhaust manifold coolant hoses running from the front of the intake water crossover and back to the water pump. Coolant passes from the thermostat housing to the s/s header tank, then out the tank's lower hose to the heat exchanger. The cold coolant from the heat exchanger is mixed right at the water pump main intake. The system is pressurized (18 psi) coolant recovery style. 4 gallons of 50/50 Green Goddess.
