I have upgraded or retrofitted older cars with r134a before with the ester oil and never had any problems with the refrigerant working with the old oil, as long as you put a few ounces of the new oil in.

The kit for r134a conversion from R-12 has everything you need to upgrade without removing all of the old oil.

Of course, in the early days of r134a conversion in the early 1990s there were people who recommended that you take the whole system apart, compressor, piping, receiver drier, etc. and replace the receiver drier and dump out the old oil.

In my opinion, this is a very expensive proposition, and good to excellent air conditioning can be had by following the R134a conversion kit instructions and installing 2 or 3 cans of refrigerant into your system.

This can be done by yourself.

Watch, if you're in California, you have to return empty cans of R134a to the store because they say that it is harmful to the environment and they want to keep track of it.

Good luck staying cool with R134a.

My ford f 150 ac clutch is surging every 5 to 10 seconds.


Usually that means you're low on refrigerant(commonly called Freon).Get someone who knows how to check pressures and do this.
It's very simple to have some added. I usually add a 2 oz. can of refrigerant oil also. Then I add the r-134 or whatever it takes. Probably needs two 12-14 oz. cans. don-ohio

2008. Why isn't the air conditioning working better?


When the compressor is replaced it should have had at least 2oz of oil inserted into it. The entire system should have been flushed to remove any foreign debris ( especially if the original compressor/clutch failed ). The system then needs to be vacuumed down to remove any moisture for a minimum of ten minutes and then leak tested to ensure vacuum holds. The system is then filled with the proper charge of freon and oil and then monitored for guage pressures and signs of leaks to ensure proper operation and effective cooling

Did you use the proper gauges to measure the high side and low side pressures as you added the 134 (I assume not Freon)? If not, it's possible you put too much 134 on the high side and either you kicked a breaker for the pressure or you just burned up the compressor.

89 s10 how much freon ac shop said 30 ounces and auto parts store said 54 and 8 of oil


The ac system should be between 30-40 psi. If your doing it yourself one small can should be enough. You can buy a kit that has the can with a hose the has a pressure gauge on it. That gauge will tell you if you have enough freon in your system. When you charge it make sure the ac is on full max before charging

My friend's AC in her 89 Cutlass is blowing warm. Can I fix this (even if only temporarily) by adding freon? If so what type do I add?


89 is R-12 unless it has been converted to R-134. If the recharge ports are threaded on the outside than it is R-12, if they are smooth it is R-134.

R-12 cannot be purchased over the counter in the U.S.

Added freon to ac and car will not cool


Needs to be checked for a freon leak, best way to do this is to recharge and add dye, with a uv light you will be able to fine the leak, most auto parts sell the dye, and the flash light you will need to fine the leak, good luck.

LOCATION OF LOW PRESSURE AC VALVE ON 1992 FORD ECONOLINE 150 TO CHARGE AC


Valve is between accumulator and evaporator on the passenger side. Your van originally came with R-12 freon, so you will need to verify that it has been converted to R-134 before adding freon. The different gasses (and especially the lubricating oils) do not mix well.
