Low coolant
Typical of worn bearings....crank, cam and rod bearings.
The schrader valve on the low pressure side of the system.
One of the causes for low oil pressure in a Chevy Tahoe could be a clogged or dirty oil filter. Changing the filter may get rid of the problem.
Should be on the low pressure line, just in front of the accumulator. It'll be capped with a black plastic cap.
Trouble code P0522 means:Engine oil pressure/switch low voltage
new body or old body? does it look the same as the 08 and 09?
The high pressure fitting is the larger of the two. The adapters and fittings used to add refrigerant can only fit the low pressure side. I have a 2003 Silverado 2500HD and the low pressure port is just above the accumulator/ dryer on a line that attaches to the fire wall.
The 2000 Chevrolet Silverado truck has two ports on top of the air conditioner compressor. You will add Freon through the low pressure port.
Low oil pressure is caused by your main and rod bearings being worn out. Most people think that their oil pump is bad but more than likely it is the bearings that are bad.
Not sure, i would say oil pump or cam bearings
If you mean a low fuel light, then NO.
