Re: 1970 Oldsmobile AC Woes

If I understand correctly, you had the shop recover the original 3.2-pound charge and then recharge the system with 2.5 pounds. I don't think you mentioned pulling a good vacuum on the system for at least a couple of hours. Was that done as well?

Re: toyota corolla ac not cooling

Incidentally, 7.75 fluid ounces also converts to 229.2 milliliters.

Re: toyota corolla ac not cooling

what is the correct amount in grams of r134 freon and compressor oil to recharge a 1990 toyota corolla diesel engine 1c 1800cc with a 10 p 15 denso compressor? My source says your car originally called for 27.0 ounces net weight (765.4 g) of R-12 and 7.75 fluid ounces (229.2 g) of mineral oil. Figu...

Re: toyota corolla ac not cooling

It appears that the original Denso 10P15 compressor on your car has a single-groove V-belt pulley while the 10PA17 variant has a serpentine-belt pulley, which won't fit your stock setup unless you change over completely to a serpentine configuration...or change the clutch.

Re: Thankful for our member support.

Tim, Just catching up with your last post. Since transitioning to the system enhancements in July, my notifications have been 100-percent accurate and timely, while previously, they were sometimes hit-or-miss. You done good :D

Re: 93 Toyota Pickup recharge challenges

I'm not sure, but Al must have meant charge through the LOW side. Attempting to charge through the high side is ill advised and downright dangerous, especially for a newbie. So keep that high-side (red) handwheel closed at all times while charging, and charge refrigerant only through the low side (b...

Re: toyota corolla ac not cooling

this car was originally r 22 so only has low pressure valve. I don't believe I've ever seen a Toyota Corolla without a high-side port, even on an original R-12 car like yours. Typically, it's near the receiver/dryer on a high-side refrigerant line adjacent to the condenser at the front of the car. ...

Re: 93 Toyota Pickup recharge challenges

Other than the seized bearing, this situation doesn't make sense to me. Are you sure the manifold gauge set is working and that it's hooked up right? Did I understand correctly that this is a loaner gauge set?

Re: 2008 F350 specs

Revisiting your topic, albeit a little late. What is the ambient temperature for those pressures? Was this at idle or 1800 rpm? Which engine in this truck? Answering these questions will be very helpful in diagnosing this. Also, a few additional questions and observations. If the under-hood sticker ...

Re: Forgot more than I know

The cause of the surging blower fan could be the relay, the blower motor itself, or faulty/corroded wiring someplace. I don't think the issue has anything to do with the blower resistor or refrigeration system. It just decided to rear its ugly head at this time for reasons not known. I would start b...
