Re: Evacuation Procedure

Here in Middle East most of the local mechanics are using vacuum pump made from air-condition compressor. I am wondering will it pull sufficient vacuum ?

Re: Land Cruiser 2001 Model GXR, AC Low Suction Line Pressure

Re-reading the thread, I'm concerned that air and moisture might remain in the system, which will raise pressures and reduce cooling, just as you're experiencing now. You are right Dear JohnHere, It must be air and moisture as you said, probably due to insufficient vacuum as the Oil was clean and n...

I didn't find any particles in the oil, may be some added UV dye as you said.

The oil was similar to light green.

Re: Land Cruiser 2001 Model GXR, AC Low Suction Line Pressure

It will be hard to determine whether the condenser is blocked or partially blocked by examining it. Blockage typically occurs when a compressor begins to disintegrate internally and sends debris downstream that lodges in the condenser. But that hasn't happened to your compressor. If you have any do...

Re: Land Cruiser 2001 Model GXR, AC Low Suction Line Pressure

" I am flushing the condenser time to time with pressurized water." Pressurized water, as in a garden hose, or as in a electric powered so-called pressure washer... Dear tbirdtbird, good question. It is not an electric pressure washer, we have a water pump fixed to the water line for wate...

Re: Land Cruiser 2001 Model GXR, AC Low Suction Line Pressure

I didn't find any dead insects or plastic bags on the front as I am flushing the condenser time to time with pressurized water. The system is working much better now, my only concern is the high discharge pressure, I guess some blockage inside the condenser or the dryer filter. I am planning to use ...

Dear JohnHere, Thanks for your time and detailed reply. Yes the fans running at a high speed was making a roaring sound. The OEM TXV was not available, I found aftermarket TXV and replaced the old one. When I removed the Old TXV, the Adjustment Screw was lose not fully tight, Last year while replaci...

Re: Land Cruiser 2001 Model GXR, AC Low Suction Line Pressure

All the components are original never changed except the evaporator and expansion valve. I have checked again with the engine at 1800 rpm with the doors open and fan on high speed, I got the following : Low Side Pressure : 25 High Side Pressure : 380 Vent Temperature : 23 at Ambient Temperate 40c an...

Re: Land Cruiser 2001 Model GXR, AC Low Suction Line Pressure

Thanks to all for your value able answers, Its Middle East the Temperature is between 40 to 45 C and the Humidity is 70-80%. Last year the mechanic replaced the leak evaporator but didn’t change the expansion value and from that day the ac cooling was very poor, I asked several mechanics to replace ...
