I just spent $ 785 to repair AC on 2005 PT Convertable with Turbo...it is an orifice system. Reason for AC failure was failed motor mounts and the engine torque pulled on the AC hoses until they failed and leaked suddenly.
On that truck you do not have an orifice tube but what you do have is called an expansion block or also known as an H-valve and there are two if you have a dual a/c system..........
That sounds like the expansion valve.
The accumulator is a component on the low pressure (vacuum) side of an air conditioning system which uses a fixed orifice tube - they won't be found on a Thermal Expansion Valve system.
There is no expansion valve. There is an orifice tue. It is located in the inlet tube of the evaporator core.
I need to find the orifice tube on a 2001 pt cruiser.
The orifice tube on a 1996 Ram 1500 is typically located in the liquid line of the air conditioning system, just before the expansion valve. To replace it, first, discharge the AC system safely and remove the refrigerant. Then, locate the orifice tube in the liquid line, disconnect the line using appropriate tools, and slide out the old tube. Insert the new orifice tube, reattach the line, and recharge the AC system with refrigerant.
Some units use orifice tubes and some units use thermostatic expansion valves to meter the refrigerant, but in either case it will be found between the condensation coil and the evaporator coil. Usually just before entering the evaporator coil.
A '99 Olds Delta 88 doesn't use an orifice tube system for the air conditioning it uses a thermal expansion valve. The location is under the passenger side dash in the heater/evaporator box. Unfortunately, you have to remove the dash to replace it as well as discharge the a/c system.
The ac system on a Ram doesn't use an expansion valve. It uses a fixed orifice system.
The orifice tube on a Peterbilt 379 is typically located in the expansion valve assembly of the vehicle's air conditioning system. To access it, you may need to remove the dashboard or components of the HVAC system. It's important to refer to the specific service manual for detailed instructions and diagrams, as the exact location can vary slightly depending on the configuration and model year.
You need to have a system performance test performed on the vehicle. If it turns out to be a leak, and the system needs to be opened up in order for parts to be replaced, you'll also have to replace either the receiver-drier or the accumulator (which one you'll have depends on whether or not you have a fixed orifice tube system or a thermal expansion valve system).
All model years of the PT cruiser will use R134a refrigerant in their air conditioning system, and PAG compressor oil.
