R1234YF

R1234YF is the new mobile refrigerant. It was introduced in 2015, and it has been mandated for use in cars and light trucks produced for the 2021 model year. R1234YF is similar to R134A, but there are a couple of key differences. R1234YF is listed by the EPA as “mildly flammable.” R1234YF is also more expensive than R134A, and servicing R1234YF vehicles requires special, new equipment. On the bright side, R1234YF is more environmentally friendly, and the capacities of R1234YF vehicles are typically less than the capacity of R134A vehicles.

 The new refrigerant is more expensive, but less is required. Often, we are asked “Why is the new refrigerant so expensive,” or “what repair shops work on R1234YF vehicles?” R1234YF is expensive because manufacturers have not been able to ramp up production to meet demand. Also, shop owners, faced with the decision of whether or not to purchase new R1234 YF equipment want to earn back the cost of their equipment as quickly as possible. Once independent car repair shops see more R1234YF vehicles, shop owners will need to purchase the equipment, and the price will drop. 


Sant Automotive has invested in a Polartek Dual air conditioning machine that can handle both R1234YF and R134A vehicles. We are eager to use it, and our price will usually be about half of what you can expect to pay for the same service at your friendly dealership. Don’t lose your cool over R1234YF refrigerant.

Do Tires Expire?

Image
  Do tires expire is a question that our customers often ask. For years many motorists have relied only on tread depth to know when it is time to replace them. Unfortunately, the age of your tires is also a factor. Over time, tires can dry out and crack. Excessive heat and sunlight contribute to this and can cause tire to unexpectedly fail, even when there is plenty of tread remaining on the tire . Tire manufacturers offer different opinions regarding how long tires will last, but the National Highway Transportation Safety Administration (NTHSA) recommends that you replace tires after six years . How do you know how old your tires are ? The best way to know the age of your tires is to check the Department of Transportation (DOT) code. The manufacturer stamped it in the sidewall of your tire. DOT numbers identify the manufacturer and the make of tires, but they also tell you when the tires were made . The last four digits of your tires’ DOT code tell the month and year of manufa...

What is a Belt Tune Up?

Image
A Serpentine Belt is the rubber Drive Belt that causes the pullies on your car's Alternator, Air Conditioning Compressor, Water Pump, and Power Steering Pump to rotate and to create electrical and mechanical power. Rotation of the alternator creates your car's electrical power. Gas powered vehicles have one or more Drive Belts, at least one Belt Tensioner, and they may have one or more Idler Pulleys. Belt Tensioners insure that the Alternator, A/C Compressor, Water Pump, and Power Steering Pump continue to spin with the rotation of the engine. Idler Pulleys are simply pulleys that do not drive other components. Idler Pulleys are used to route the Serpentine Belt.  With use, a Serpentine Belt will stretch and wear.  Belt Tensioners and Idler Pulleys also wear, and this will cause additional belt wear. When a Serpentine Belt breaks, the components that it drives will not longer function. Because of this, Sant Automotive recommends that you replace your Serpentine Belt(s), Idler ...

What Do Spark Plugs Do?

Image
  Spark Plugs are the small electrical parts that provide the power to ignite the fuel in gasoline powered devices. As electricity passes between the Spark Plug's electrodes, gasoline ignites causing an explosion that powers your vehicle. Spark Plugs fire once every two engine rotations. This means that if your engine is running at 800 RPMs, your Spark Plugs will fire 400 times per minute. The heat produced by these explosions causes the Electrodes to wear which increases the gap between the Electrodes. The increased gap causes your vehicle to use more fuel to produce the same amount of power.  Worn Spark Plugs reduce Gas Mileage, and unburnt fuel will damage your car's Oxygen Sensors and its Catalytic Converter. Also, the longer that plugs stay in a vehicle, the more likely they are to become stuck in the engine's cylinder head. If a spark plug breaks, it can be very expensive and time consuming to extract it. For these reasons, Sant Automotive recommends that you change y...
