A/C Repair - 2012 Honda Civic Expansion Valve Review - DIY Replacement

A/C Repair - 2012 Honda Civic Expansion Valve Review - DIY Replacement

This is my honest review and I am glad you are here.

Today I talk about the details and benefits of this OEM Denso A/C thermal expansion valve that I recently purchased on Amazon. And then I'll show you how to pull the evaporator out, remove the old expansion valve and install the new one.

But first... Will this expansion valve fit on your car?

Although this video is specifically for my car, a 2012 Honda Civic EX, this is the expansion valve that will fit all Honda Civic models...2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, and 2014 (if you have a Civic Si, double check the fit). And it is even the same expansion valve used for the 2007-2011 CR-V, 2010-2014 Insight, and the 2011-2016 CRZ.

In addition, it's used in the 2006-2011 Acura CSX, and the 2007-2012 Acura RDX. It's even used in the 2009-2010 Toyota Corolla, 2006-2012 Toyota RAV4, and the 2009 Matrix. To add to all that, many Subaru Tribeca, Legacy, and Outback models used this expansion valve in their AC systems back in 2005 to 2009.

This is a follow up to a video I uploaded last month where I evacuated and charged my AC system on my Honda Civic with R134a. But my problem of not cooling persisted, so that lead me to diagnose the problem (with the help of my new manifold gauge set) as the thermal expansion valve.

So to get the full story of my journey, watch part one here:    • DIY Tutorial - Proper R134a A/C charg...  

The bottom line is that I thought that I only had a small refrigerant leak before I started, but it turns out with the help of my manifold gauge set I found that I had a restriction in the low side of the system instead.

I wouldn't have known this if I had not of done a proper AC evac/recharge first so I could eliminate that as a source of the no-cooling problem. By reading the gauges after the charge was complete (as seen in part one...link above), I could see that the low side was way too low (going down even into a vacuum while the compressor was on) indicating that there was a severe restriction, most likely the expansion valve in my case.

Many folks are afraid to try and work on their AC system, but after you watch this video you'll gain confidence, and you'll save yourself tons of money by giving it a try on your own. This is totally DIY, you'll see! (Do It Yourself)
