How to find the O-ring set for 1986 volvo 245 (wagon) from ACKIT.COM?
Also, how many OZ mastcool vacuum pump oil I need for my 1.5 mastecool vacuum pump?
Thanks for help.
Do you think one bottle oil (18-ounce) is enough for one time running? my vacuum pump is a 1.5 CFM mastercool vacuum pump.
Yes, even the larger pumps only need one bottle to drain and refill. But don't let that stop you from buying more.
Thanks for the support!
Thank you. Just ordered 3 bottles vacuum pump oil(3x18OZ). I think it will be enough for this years AC project.
By the way, I will flush my old car and need flush gun. There is "Pulsator" DIY Flush Machine(Price: $283.50).
Does it need one additional air pressure tank? I did see the demo video and did not see any one mention it need air compressur tank or not.
The pulsator needs an external air supply; not a tank.
I just used one of these. It's a nice machine. It holds one gallon of fluid in the tank.
I used about 1.5 gallons of flush fluid for the evaporator and lines. I replaced the condenser. I could have used less than a gallon had I reused any of the flush fluid after the first round through.
OK, sorry for being late to the party. It does seem that your questions have been answered but I will add...
The Pulsator Flush Gun is not a charge up with pressure and flush device. It uses a continuous flow of compressed air to operate the pulsating flushing action, at about 4-5 CFM. No worries if you have a small home shop compressor. It will run it until the flusher outruns the compressors ability to recharge the storage tank. Just stop flushing and allow the pressure to build back up and then you can continue flushing.
The flushing tanks capacity is one gallon and at least one gallon will be required per component. You may need more depending on the severity of the failure and the contamination load.
Dry, dry, dry air is required for A/C work (when Nitrogen is not available), make sure you have a good filter on your compressed air supply. Attach direct air line to the component and blow for 20-30 minutes to remove all the solvent. Use the "pop" method to be sure all debris, oils , and solvent is removed. If the "pop" test reveals more issues, more issues must be resolved before you reassemble.
See the "Navigation" window at the bottom of this page; you can read a lot more about flushing in the "procedures forum"
