150 high 75 low
High side and low side refer to the pressure in the ac system. Ie The high side is the high pressure line and low side is the low pressure line.
At 80 degrees air temp expect low side in the 20-40 range and high side 200-300
No, the liquid (discharge) line is the high pressure side. The suction line is the low pressure side.
Red is the high side.. The low side is blue..
The compressor changes the low pressure gas into a high pressure gas which then has the heat of compression removed in the condensor to turn it into a high pressure liquid.
This has a lot to do with the ambient temperature and humidity. but a ball park figure outside temp 90 degrees F. and low humidity could be High side pressure 180 - 225 PSI and low side pressure 30-50 PSI. at idle speed with a/c on high
On a manifold gauge set, there are two gauges. The gauge encased in red measures pressure on the high pressure (discharge) side. That's the "high side gauge". The other will be incased in blue, and measures vacuum pressure on the low side.
The high pressure side.
Newer (post 1993) A/C systems using the current 134a refrigerant need a low side pressure of 35 to 45 psi, and a high side of roughly the outside air temperature plus 100. Say it's 95 degrees outside as it is today - then a high side pressure of 195 psi is about right. Use gloves and safety goggles for the event that something lets go in oyour face. IT happens! Be safe - or go have a pro do it for you.

its can be a restriction in liquide line
The correct tire pressure as listed on the front side door panel is 33 LBS.
