Help with my honda

mybuddy on Mon October 15, 2007 9:31 PM User is offline

Year: 2000
Make: honda
Model: civic
Engine Size: 4
Refrigerant Type: 134
Ambient Temp: 90
Pressure Low: 30
Pressure High: 300
Country of Origin: United States

My 2000 honda civic ac compressor clutch is engaged while the ac is turned on and the car is running. But the inside air is not getting cold at all. my high side does seem to be high in my eyes on my gauges does this seem to be a weak compressor or is there something else i can check. What kind of readings should i be at with this type of system. Can anybody tell me where i can look to see this system on the internet. AnyHelp Please Thanx

Check your condensor fans & air path. Your high side is too high for that ambient temperature.

The compressor is good if it can push 300 psi. Do NOT add anything to this system! your pressures are already excessive.

Make sure the fan(s) are running, and that the condensor is clean & free from restrictions like mud or paint.

You could very well be way overserviced, bleed some off and pressure and vent temp should come down, of course we all recommend that you have it recycled and the correct amount of gas put in.

Give all the dirty details
and dont forget the LO & HI pressures
Year, Make & Model would be nice too

250 PSI is about maximum at 90*F, but go along with Bohica in checking the fans and condenser rather than bleeding it off, assuming the system was not serviced. Vent temps are only half the story, are the evaporator inlet and outlet tubes ice cold? Can also be a heater related problem, find out what's wrong first before making changes, but never hurts to clean things up. Often commented the only difference between a brand new system and an old system, is dirt.

You should have been getting some cooling w/ those pressures, although the high side is high. On Honda's w/ manual heater controls a frequent problem is the heater core flow control valve is mis-rigged allowing the valve to remain open when temp setting is full cold. Not familiar w/ civic arrangement but Honda tends to use same arrangement on all models. You can manually close the heater control valve to see if this has an effect on cooling.

good luck

See you down the ROW.

OR safely and gently pinch off the heater hoses going into the firewall, just one is fine, it doesnt matter which one, as long as the flow of water stops. Several inches from the firewall, not too close.
