We added freon to the air conditioning, it was running good then our temperature rose a little , then we noticed our oil gauge going up, the car died when the oil pressure hit 120 it was smoking alitlle, we tried to restart the car but the oil gauge was down to zero the engine turns but will not start what can it be

Are you sure that you didnt put the freon into the fuel line as there is a cap and fitting almost the same as the air conditioning. Check your oil level and check google if there is a low-oil cut off switch on that particular vehicle and if so bypass it to see if it will start. Sounds like an electrical issue more than anything perhaps wires burnt and touching something near the exhaust. Not sure if the two are related.

SOURCE: the engine seems to overheat and the internal heater blows cold

First thing to do is check the coolant level. Low coolant can cause this. Next is check the thermostat .

SOURCE: air condition blows hot air but it has freon

You may have created an over charged condition and at this point the a/c compressor will cut off on high head pressures. This can be verified by installing gauges to the systems high and low side service taps and reading the pressures.An overcharged system will start the compressor briefly but soon cuts off once pressure goes to 350 - 400 lbs on the high side. Acceptable pressures for this system should be no greater than 250 high and low suction should drop to 40-50 psi.You might recover the charge and evacuate the system,then try bringing the charge back to proper level.A sight glass in the reciever drier really helps determining proper fill.Once all bubbles have dissipated from the sight glass during charging ,one should stop at that point to avoid overfilling.Too much freon is worse than a low charge especially in hot ambient conditions....

SOURCE: 2001 pontiac bonneville SSEi 3.8 l supercharged.

I have a 2000 Bonneville - I had a problem with the car stalling out - then it did not want to start back up. (When it did it would idle up and down and then die) I changed out the mass air flow sensor - now I have not had a problem. Good luck with it.

SOURCE: adding freon to the air conditioning

look for the thick pipes vs. the thin pipes and a quick connector that goes on to the hose that fills the r134a via a can of freon.

Or, do you mean, where is the freon leaking out of? The freon leaks out of o-rings, seals, and possibly the compressor.

I had a compressor changed in my 1990 Cadillac Deville because it was leaking there. This is a common problem on older cars.

Good luck.

MY RAV4 engine stalls while slowing down. Whats the problem do you think?

well lets try inspecting your coolant temp sensor for the ecu, not for your gage it is green whit two wires going into it, if any corrosion replace sensor and pigtail, your ecu may be dumping lots of fuel thinking eng still cold when is hot, this also wahs off your rings and by adding oil bumps compression and starts, hope this helps.

How do i find blockage in air conditioner hoses after freon added and gauges dont register that there is freon

Diagram on how to install freon for air conditioning

freon is added though the suction side service port. if you don't have a manifold gauge set to check system pressures first then you might be doing more harm than good. if you took the system apart for any component change, then you will need to replace the drier/reciever and evacuate the system using a vacum pump before adding freon.

Recent coolant problem. replaced thermostat because car would not blow warm air, temperature gauge seemed normal. seem to be fixed temporarily. couple weeks later temperature gauge increases to hot and...

could possibly be a head gasket problem. check the oil and make sure the coolant is not mixing with the oil... also thick white smoke out the tailpipe is a good indicator of a bad head gasket

How many pounds of r134 and how much oil ozs.

somewhere around 1.6 pounds (1lb.14ounces) of R134a if system is evacuated and 3 ounces of oil with new compressor.
keep pressure on the low side around 34-37psi & it should blow snow. Below are normal car AC pressure readings with 134A.
  • Normal readings on high and low side with AC OFF (static pressure) – Depends on outside temperature, but normally is between 80-105 PSI
  • Normal low side reading with AC on high speed and MAX & engine at 800-1000 RPM’s – Ranges from 25-35 PSI –
  • Normal high side reading ranges from 200-350 PSI
Don’t assume that if adding little Freon is good that adding a lot is better! Overcharging just a little can decrease the performance of the system and possibly damage the compressor.
DIY recharge kit:
With the AC on the coldest setting, use a thermometer in a middle vent. Normal vent temperature readings will vary depending on the (ambient) outside temp. The vent temperature should range from around 42-55 degrees in my experience. If normal gauge readings are obtained and the vent air is cold – STOP don’t overcharge the system.

Air conditioner compressor runs - freon is up to proper level....not cooling??

BOTH High and low readings should be checked to have a better idea of what is going on with an AC system but based on the limited information… the compressor is not engaged or is not pumping. Below are some things I would check;

1. Check the high and low gauge readings with the AC on & set on MAX/Recirculate, middle vents with the engine at 2,000 RPM’s, blower speed on high.

2. Check the vent temperatures with a thermometer from the middle vents, far right & far left vents?

3. What is the outside temperature at the time the readings were taken?
4. Check to see if the condenser fan blowing strong?

5. Notice if compressor clutch is cylcling excessively.
Could be overcharged, not enough air going across condenser fins, compressor not pumping sufficiently… BOTH gauge readings are really needed to get a better idea.

The a/c on my 2006 honda pilot is not owrking and appears to have a low refrigerant charge. I want to recharge it and find the leak with die. what is the amount of 134a to be fully charged

Adding freon or topping off a cars A/C system is the most common task performed to restore performance and get cold air blowing again. However, adding refrigerant isn’t always the solution for car air conditioning problems. There can be many other things wrong besides a system being low on refrigerant. To diagnose problems, an A/C manifold gauge set is needed to read high and low side pressure readings. Avoid adding refrigerant with a simple charging kit like the ones sold at parts stores. Don’t add any stop leak, this can cause problems in the compressor, expansion valve or condenser.
Keep in mind that using an A/C gauge set and seeing BOTH high and low side readings can help in diagnosing the problem when you know what to look for. First, on a 134A system the high and low side service ports are different sizes. AC gauge sets have color coded hoses, the blue color coded hose has a connection that fits on the low side service port and the red hose has a connection that will only fit onto the high side. The yellow hose won’t hook up to anything if just checking the readings; it can be used to connect to a vacuum pump or attached to a refrigerant can or tank.

*Make sure the condenser fan comes on when the readings are being checked.

Normal readings on high and low side with AC OFF (static pressure) - Depends on outside temperature, but normally is between 80-105 PSI
Normal low side reading with AC on high speed and MAX & engine at 800-1000 RPM’s - Ranges from 25-35 PSI - Note that on many Chrysler products a normal reading on the low side may be 15-25 PSI
Normal high side reading ranges from 200-350 PSI

Don’t assume that if adding little Freon is good that adding a lot is better!  Overcharging just a little can decrease the performance of the system and possibly damage the compressor.

With the AC on the coldest setting, use a thermometer in a middle vent. Normal vent temperature readings will vary depending on the (ambient) outside temp. The vent temperature should range from around 42-55 degrees in my experience. If normal gauge readings are obtained and the vent air is cold - STOP don’t overcharge the system. The only proper way to remove refrigerant is with a AC recovery machine so if this is being done at home I can’t emphasize enough not to over charge the system. And actually the best way to insure the proper charge is in a system, is to use an AC machine to recover the R143a and then evacuate and recharge the system with the correct amount. Most cars have the specified amount on a decal under the hood. 

Hope this helps. Keep me posted, be glad to help get you cooled again.
