Where is the low side coolant fitting on a GMC Yukon?
Locate a canister wrapped in silver insulation at the back passenger’s side of the engine — this is the air-conditioning accumulator. Trace the pipe that runs over the top of the accumulator from the fire wall forward, and locate a dust cap marked with an “L” approximately 5 inches away — this is the low side charging port.
What kind of hose does a truck air conditioner use?
Like refrigerant hoses, theyre usually stamped to show the kind of liquid and the level of pressure. Some truck air conditioning systems use hydraulics instead of the engine to power the air conditioner compressor. These hoses have different requirements from standard refrigerant hoses.
What happens if the a / C hoses stop working?
If your A/C system stops working, hoses or fittings could be the problem. These parts keep your system running efficiently, and they do wear out over time. Fortunately, finding replacement parts is fairly simple.
Why does my GMC Sierra have a leak?
Just a thought…. 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak…… They use the same part on many cars. From Chevy’s to VW’s. Chick, i have a 1997 GMC Sierra K1500 with a 5.7L that has the same problem.

Why does my GMC Truck have a low coolant light?
The truck now has about 35,000km on it and the low coolant message is appearing at almost every start up. The tank is not low but I topped it off right to the cap and the message still pops up. I stopped by the dealership and they said this is common as the sensor is in the surge tank and the fix is to replace the surge tank to the tune of $600.

Can a PCM turn off a low coolant light?
Yes. If the light goes out then the switch is bad. If not then you could possibly have an open wire and the pcm isn’t seeing that the switch is closed thus keeping the light on. A multi-meter can tell you if a wire is open. Yes.
How does the low side coolant work on a GMC Yukon?
The liquid is then passed through an expansion valve where air, cooled by the Freon, is blown into the cabin. Occasionally, the Freon in the air conditioner needs to be recharged; the low side charging port allows this.
Raise the Yukon’s hood and prop it open. Locate a canister wrapped in silver insulation at the back passenger’s side of the engine — this is the air-conditioning accumulator.
