I purchased a kit from the auto parts store. It has sealer, coolant, oil, etc. It says to drain the whole thing. I dodn't but just found the low side and put it in. That's been three years ago and it is still going strong. Some will tell you that it will ruin the system. I have done it in over twenty cars and never had a problem. If it does anything, it swells the seals which helps seal things up. The kit has adapters for any car but just make sure you put it in the low side as it can be dangerous which I'm sure you know. Hope this helps.

Freon for 1990 oldsmobile 98


This car uses R12, it is no longer available, you must convert it to R134, this requires the compressor and reciever dryer be replaced and the system flushed out and the new PAG R134 refrigerant oil be added and new charging port kits installed. Is that car worth this effort?

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.
Thank you for using fixya and be safe.

What type of freon does my 99 chevy blazer require


Should use r134...Large quick disconnect service ports will verify that and generally there is a label on the compressor.

How do I recharge the AC freon on my own?


You should have R12 freon in a 1990 but you can put R134 freon into that system the only problem your going to have is the adapter for R12 is different from R134 after you get the adapter you need to put the freon in the low pressure valve not the high pressure, you will know which one because the adapter only fits the low pressure valve which is located on your AC lines under your hood, theres a little cap thats either blue or black you unscrew. You can't buy r12 anymore because its not good for enviorment so buy R134. you can buy at any parts store for like $5 to $10.

AC is not working


Sounds like the A/C system just needs to be recharged. When was the last time you had this done? Just take it in to your mechanic and he can do it for you and if that's not it for some reason, then he will be able to find the problem but most likely you need more freon added.

R12 to R134


You have to have the R12 completely evacuated. This is done at a repair facility that works on A/C. The only thing after that is screwing on 2 fittings to your existing lines and charge your system. Companies make retro-fit kits so the owner can do it themselves. These kits are available at most part stores.

FILLING UP THE FREON IN MY 2000 NISSAN MAXIMA SE


2000 maxima is filled with R134, not freon. You don't need retro fit kit. Get couple of cans of R134 and pump it into the low side valve /small fiting, while A/C compressor is engaged. If your compressor is not coming on, jump the low side pressure switch to make the compressor come on and than the R134 will get sucked in to your system through the low side line. The proper way to do this is to put a/c system under vaccum for 15 minutes at least and watch for leak/gauges coming/loosing vaccum. Than pump R134 into the HIGH side valve with engine OFF.
