No Oil Pressure After Replacing Water Pump
Does anybody have any idea why my dash gauge would show oil pressure all the way down?
I had oil pressure registering before replacing my water pump. Any help would be greatly appreciated, as I need to drive the car tomorrow, and I am worried if there really is no oil pressure that will end catastrophically. |
Possibly pulled the wire off the oil pressure sensor located just above the oil filter, or even damaged the sensor. Take a look.
|
I see, my PS Pump knocked it off, or maybe broke it?
If it screws in the chances are I broke it, I'll try to get pics of what the sensor looks like as it is now. |
Ya, check the oil sender unit. It sticks out and can be broken easy. https://www.gmforum.com/trouble-shooting-test-procedures-141/oil-pressure-sensor-location-284737/

Thanks for that link Danthurs, I broke it when I sat my PS Pump down on it.
Would it hurt to make a 6 mile trip to the grocery store before I can get this replaced, or would that be bad? |
Am I going to have to drain my oil to replace this?
|
No problems at all. It only reads the pressure, not control it.
No need to drain the oil. A small amount will come out. |
Sweet, good to hear, thanks for the help Dan!

Question, do you know of anybody that has had success using the cheaper sensors?
Like the Airtex/Wells, or SMP one? I ask because I read some had issues with inaccurate readings with non OE AC Delco sensors, so I'd normally just get the OE one, but money is beyond tight, so if I can get the sensor for around 20.00 instead of 40.00 my wallet would be happier. |
Any should be fine. It's only giving you a reading, that is all. You want accurate, you will need a mechanical gauge.
