Escalade oil pressure low when cold, ok hot.
I have a 2006 Escalade ESV 6.0 engine. Oil pressure low when first started.
Very low when temps get to freezing. But when warmed up, the pressure
rises. I thought the sending unit, but changing that didn’t make a difference.
Everything I know is pressure should go down when warm.
This has me stumped.
Changed to different oil and filter too just in case something wrong but no
I'm not gonna lie to you, you wasted money. The oil pressure gauges in the GM vehicles are slow and don't catch pressure right as it occurs and takes time to adapt and even in cold weather can shut off completely and when the engine starts its obviously gonna be low at idle and when you start driving.
So is it ok to drive? Mine is doing it as well
