ACDelco Gold 15-5754 (19189768) Air Conditioning Orifice Tube

Work great.just be patient and a little knowledgeable it Work coming out and inserting for a 2008 chev express 4.8l 2500 model

Works as it should.

The size of this was smaller than I imagined. But it does work well and helped my older Tahoe's AC system. Someone had put stop leak in it at some point, and that all coagulated on the screen of this part. Swapping it out seems to have helped. But keep in mind you absolutely must vacuum pull the system first before installing this.

Good

It's an orfice tube

Came quickly and worked as good as OEM. Good purchase!

Great fit good quality good price for the money

This ACDelco part number 15-5754 is for a front AC system only. My 2003 Express van under went a rear AC delete and while the system was going to be opened and evacuated, I replaced the orifice, the high side valve, and the low side shcrader valve before the second evac. and recharge. The old orifice suprised me that it even worked, I expect it was the original unit, and had the build up to support that thought. When I was done the AC system performs like a new van. The removal and installation of the orifice only taks a minute or two (be sure your system is professionally evacuated first) and for the $10 or so, there really is no reason not to replace this underated player in your AC system.

Excelente lo recomiendo

Replaced this in my 2016 GMC Savana as it was plugged. Located right at the evaporator piping entrance. Symptoms were: AC worked when you were moving but when you stopped, most dumped out on a high pressure relief. Very little refrigerant was left over so AC never started. No existing leaks plus condensor and evaporator were spotless. Replaced the o-ring to part# 13579648 Pressure test with nitrogen after replacing; 100lbs for 30 min and evacuate for 30 min. Weigh in charge of R134a. AC is ice cold now!

works well

This tube works great! DO NOT Buy a variable tube as it made my AC system groan each time the compressor came on. The orifice tube location on my 4.3L S10 is in the high pressure tube directly under the accumulator dryer. Use needle nose plier, get a firm grip and pull it straight out. Installation of new tube goes in with the filter facing towards your pliers (the orifice tube oring goes in first).
