High Performance Four Seasons 38641 Orifice Tube for Enhanced Efficiency and Reliability Review

This automotive replacement part is a game changer. Durable and efficient, this orifice tube ensures smooth operation of your engine cooling and climate control. My car's A/C started working again the moment I got it installed. The only downside is that it requires professional installation. Overall, highly recommend it!

Looks good but I haven't installed it on my 3.9 liter Dodge Dakota V6. It is housed in a thicker aluminum tube that comes from the supercharger, where it runs through the body panel to the right of the engine's radiator and leads to the condenser in front of the vehicle's radiator. It might sound confusing, but it's hard to put the place into words. I had to clean and use the old one.

I bought this when I was rebuilding the air conditioning on my 1994 Jeep Grand Cherokee. Unless you are an air conditioning technician, do not buy this. For the 1994 model (and possibly similar ZJ models) you will need to purchase a complete fluid line that includes a hose with an orifice. You can't just line this up, you need special tools to take out the old bore tube and crimp this. Revain should not sell this part for this vehicle. At least it was only $3 wasted.
