Orifice tube use .062 instead of .067

bteddy on Wed August 06, 2008 1:13 PM User is offline

Year: 1994
Make: Ford
Model: Explorer
Engine Size: 4.0l
Refrigerant Type: R134a
Country of Origin: United States

92,93,95,96,97,98 Ford Explorers use red color code orifice tubes .062", 94 Ford Explorers use Blue color code orifice tubes .067", why?

What would happen if I installed a red color code .062 orifice tube in the system?

The system uses 46 pag oil. Someone stated that the oil circulates thru the system.
I thought the majority of the oil stayed in the compressor and only a little of the blowby moved thru the system?


Does anyone know where I can buy or have custom made a PARALLEL FLOW 4-PASS CONDENSOR?
Width: 19 to 21 inches
Height: 16 to 18 inches
Thickness: 1 in
inlet: #8 male
Outlet: #6 male


Thank You

Changing the orifice tube size by .005 will probably have a negligible effect on cooling performance.
The lubricant does indeed move thru the system. The compressor is the motivator for migration of lubricant. The correct charge rate is essential to insure complete migration of lubricant thru the system. An undercharged system will 'starve' the compressor of lubricant...and of course, the end result will be a severely damaged or destroyed compressor. Excessive noise is normally the first indication of lack of lubricant flow....and over heated or burned clutch is also possible.....and the final...complete compressor failure.
Why not check with site sponsor, they may have just what you need for a condenser.

I tried the site sponsor first (6 weeks ago) they couldn't help me.

Thanks for the response.

Closest one we would have is the 24-50001

Question...what is wrong with the unit TRB is quoting? Is this condenser for use in the Exploder....opps Explorer.........?
Location of a 1" thick PFHE condenser may be a bit difficult. Most of the units today are 5/8 in. thick. These units are multi-pass units with flow orifices 21-23 per tube, .015 id.
