New refrigerant HFO 1234yf service for cars

What is HFO-1234yf Refrigerant?

Scientifically speaking HFO-1234yf is 2,3,3,3-Tetrafluoropropene.  But we’re not scientists here at Highline, we are mechanics.  So let’s talk about what R1234yf is to the rest of us.  If you’ve been around the car industry for anyHFO-1234yf-AC-Service-Mesa-AZ-Highline-Car-Care length of time here in Mesa AZ, you may remember 1994 when refrigerant R12 ceased production and R134a became the standard automotive refrigerant.  Scientists had found that R12 depleted our ozone layer and was bad for the environment.  R134a was significantly safer, and has a GWP (Global Warming Potential) of 1,430, compared to R12’s GWP of 10,900.

While refrigerant R134a was significantly safer than it’s predecessor, it still has a considerable global warming potential of 1430.  In 2006 The European Union implemented directive 2006/40/EC that required all newly manufactured automotive AC systems to have a GWP below 150 by 2011.  It turns out that HFO-1234yf has a GWP of less than 1 and fit the bill.  As far as commercially produced refrigerants go, this is likely THE safest for our atmosphere that will ever be developed.

HFO-1234yf does have one nasty little character trait though – It is mildly flammable.  Automotive refrigerants are constantly exposed to high temperatures, and car AC systems can spring a leak in many common circumstances.   A front end collision will likely puncture your car’s AC condenser which will release refrigerant.  A failed AC component can do the same.  Road debris may also create system leaks.  All of these scenarios make scientists nervous – All it takes is a heat source to cause a fire and furthermore, create very toxic by-products.  This being said the European Union performed real world tests, as did several other manufacturers (Mercedes and Chrysler), along with Germany’s Federal Motor Transport Authority.  Results varied between tests, but generally speaking it was found that HFO-1234yf will not ignite without a heat source greater than 1650 degrees Fahrenheit.  This is significant because at 1650 degrees every single fluid in your vehicle would be on fire as well, in which case it would not really matter if your refrigerant was flammable or not.  This being said, auto manufacturers have unanimously agreed HFO-1234yf is safe for use in automotive AC.

 

Which Vehicle Manufacturers use HFO-1234yf Refrigerant?

If you are living in the European Union, any vehicle that was made in 2011 or newer contains HFO-1234yf.  But what about back here in Mesa AZ, and the US?  General Motors started using this refrigerant in 2013 in certain Chevrolet, Buick, Cadillac, and GMC models – All models will be converted by 2018.  Chrysler, Honda, and Subaru began switching over in 2017.  One key difference with the switch over of HFO-1234yf vs the previous switch to r134a is that there is currently NO deadline for manufacturers to make the switch.  While we have no factual data, we at Highline Car Care believe most vehicles will contain HFO-1234yf by 2025.

 

How Do I Refill, Service, or Add this new refrigerant HFO-1234yf to my car or truck?

We’ll spare you the lecture for now, as to why you should not service your own car air conditioner.  But if you’d like to read exactly why, click here

That being said, we recommend you visit a 609 MACS certified AC shop whenever having your air conditioning serviced or repaired.  HFO-1234yf machines are specific to this refrigerant and you cannot use a r134a machine to service your new style system.  At Highline Car Care in Mesa, AZ we have done our homework.  We invested in a dedicated HFO-1234yf machine even though 95% of the shops in the Valley do not own one.  We pride ourselves in being leaders in our industry.

HFO-1234yf service is very similar to the old system.  Refrigerant must first be evacuated, the system will be pulled into a vacuum to remove any air or moisture, and the proper amount of refrigerant will be added to the system.  Remember, a discrepancy of +/- .5 ounces can cause system malfunction or failure.

 

Is HFO-1234yf AC service expensive?

Short answer – You bet!  This new refrigerant is currently over $150 per pound – Most new vehicles take 1-1.5 pounds.  Previous r134a refrigerant averages about $20 per pound.  We expect the cost to head downwards once availability grows, but in the meantime expect to pay a bit over double what your old system costed to service.

Nissan GTR R35 Bellhousing Repair

GT-R R35 Bellhousing Highline Car Care Mesa AZ

Bellhousing failure is an all too common issue with the R35 Nissan GT-R.  It first manifests itself as a faint rattle at idle, but will eventually become an unavoidable clanking sound that reverberates in your head and sucks the pleasure right out of your Sunday drive.  Let’s take a look at what exactly the bellhousing is, what it does, how it fails, and how the folks at Highline have made them more durable:

First off, the R35 GT-R is an all wheel drive vehicle with the transmission located at the rear of the vehicle (as if you didn’t already know!)  That being said, a simple bellhousing is mated to the rear of the engine in lieu of the contemporary transmission placement. The bellhousing is an aluminum housing with a shaft running through the middle.  This shaft is connected to a damper at the engine end that bolts to the engine flywheel – It looks like a sprung hub clutch disc at a quick glance.

GTR Bellhousing Center Shaft with Bearings Highline Car Care Mesa AZ

Center Shaft Assembly with Support Bearings

 

 

The other end of the shaft bolts to the driveshaft which travels rearward to the transmission/transaxle.  The shaft is supported by two small bearings inside the bellhousing, and herein lies the problem….  This shaft is subject to 500+ horsepower, and well over 6,000 RPM’s at times.  The resulting torque will cause the bearings (made of steel) to wallow out the aluminum bellhousing over time.  The bearings will eventually float freely from the housing, and the clanking sound is caused by the bearings (and shaft) rattling around.  Believe it or not, Nissan has YET to devise a cure for this.  Even a brand new $1600 Nissan OEM bellhousing may only last a handful of launches.  This is where Highline stepped in with their expertise.

A Modified Bellhousing that is Cheaper AND Stronger than OEM – Only at Highline Car Care

A Bellhousing being milled for new sleeves at Highline

If you’ve followed our blog, you might already know that Wes (Our Owner) picked up a 2010 GT-R project a while back.  It had the “rattle” from the very beginning, which progressively got louder.  It eventually got loud enough to sap the joy out of driving and a solution was to be devised!  In typical Wes fashion, he did not rest until the matter was resolved.  The bellhousing was removed from the car – The Nissan labor guide calls for removal of the entire engine to replace this item.  However, we are able to remove it by supporting the engine and lowering the subframe.  Much less invasive, and quicker!

Once the bellhousing was removed and disassembled, we devised a fix.  Replacement bearings were ordered, and the bellhousing itself would need to be repaired so that the new bearings would not come loose.

The “Highline” Bellhousing is bored out and fitted with steel sleeves that have been retained by set screws

The Highline bellhousing uses precision milled steel sleeves and only high quality replacement bearings to ensure trouble free operation.  Nothing is 100% bulletproof, but we have yet to see one of ours fail.  That’s saying a lot,

considering Nissan hasn’t been able to solve the problem in 10+ years.  Give us a call or shoot us a message today if you’d like to have your bellhousing replaced – The experts are standing by

Your Toyota Prius MFD Display Plays a Vital Role in Function and Convenience, Let the Pros at Highline Keep it Functioning Properly

Is Your Toyota Prius Multi Function Display Touch Screen on the Fritz?

Toyota Prius MFD Navigation Touch Screen Repair Mesa AZ Highline Car Care

A non responsive MFD will not light up, but will not respond to touch

Let the Pros at Highline take a look.  We are currently able to repair non responsive MFD touch screens on all 2004 through 2012 Toyota Prius models for a FRACTION of the price you have likely found at Toyota.  This is a specialty service that we have been offering since 2012, as we saw the need for an economical solution to touch screen failure.  Some cell phone repair companies claim to be able to “repair” your touch screen by cutting your digitizer open and using a solder circuit pen to patch the failed connection.  The question is though, do you really want an unqualified cell phone salesman disassembling and patching your $6,000 navigation unit?  Sounds risky to me.  Our technicians are ASE certified and will actually replace the failed touch screen in order to offer a 24 month/24,000 mile warranty on our repair.  We feel this is the only way to do it right.
