low suction and low discharge pressure!

jazz on Mon May 04, 2009 9:59 PM User is offline

Year: 1996
Make: honda
Model: accord
Engine Size: 2.4
Refrigerant Type: r134a
Ambient Temp: 80
Pressure Low: 5
Pressure High: 50
Country of Origin: United States



System was not cooling well. Checked pressures and low side showing a vacuum (static).
I had the system evacuated, changed the expansion valve and pulled a vacuum for 30 mins.
Checked the system for leaks by leaving it for 1 hr. No leaks.
Filled the system with 23oz.(as per info on engine compartment).
Pressure was 0/35 psi. Added 6oz more, pressure went up to 5/50psi. Outlet temp 50F.

This is on the low side and the car used to cool down to 40F before. The dryer outlet side
felt warm to hot. I would assume if it was clogged, the outlet would have been cooler?

Any ideas as to what may be going on? Dryer, Discharge hose, compressor????

Thanks
Jazz

2.2 L uses 23 ounces and the 2.7L 21 ounces.

With as much refrigerant you claim to have in the system it sounds like a weak pump. Pressures should be around 20/210 at that ambient.
