Automotive Tips from Car Doc On The Island: Making Your A/C System Last Longer

Venice drivers know that if their air conditioning system isn’t making cool air like it used to, there is a problem. It may be as simple as adding more of the right kind of refrigerant.

Your A/C requires special compressor oil, which circulates through the system along with the refrigerant, to lubricate and protect expensive components and keep seals and gaskets from drying out. If refrigerant has leaked out – so has the compressor oil. This oil needs to be replenished whenever refrigerant is added.

An air conditioning inspection at Car Doc On The Island will uncover any potential problems and identify any necessary repairs needed to get Venice drivers on the road to cool air once again.

Exhaust Service at Car Doc On The Island in Venice

Whenever they hear the term "exhaust service," most Venice residents think about exhaust pipes and mufflers. Well, actually, exhaust service at Car Doc On The Island is a lot more comprehensive these days. For example, catalytic converters were mandated in 1976 and on-board emission control computers in 1990. Governmental emissions requirements have forced manufacturers to come up with much more sophisticated ways to comply with environmental regulations.

Exhaust service has really become exhaust and emissions service. High-tech computer controlled emissions devices are now a big part of exhaust service. Because it is so sophisticated, your recommends you have your emission system checked out by a qualified Venice exhaust technician regularly to make sure everything is working right - usually every 6 months or 10,000 miles/16,000 kilometers.

If your Check Engine light comes on, especially if it's flashing, get your car looked at right away. Technicians at Car Doc On The Island in Venice handle emission problems everyday. You might have exhaust or emissions trouble if your car is difficult to start, runs rough, is noisy or smoking. Call Car Doc On The Island at (941) 786-1595 to schedule an appointment if you experience these problems.

Let's review the exhaust system. We will start from the top with the exhaust manifold. That is the part that attaches to the engine and collects the exhaust from the cylinders and directs it into the exhaust pipe. Exhaust gaskets help seal the connection with the manifold and various other joints along the way. If the manifold is cracked or loose or a gasket is leaking, gases could escape into the passenger compartment where you ride. Carbon monoxide can be deadly, so it is important that your exhaust system doesn't leak. The exhaust pipes connect the various components. They can rust or be damaged by a rock, so they need to be inspected periodically.

Next is the catalytic converter. This part looks like a muffler. It changes chemicals that are dangerous to your health and our Venice environment into harmless carbon dioxide and water. It doesn't require any maintenance itself. But eventually they wear out. Venice drivers find this out when their car fails an emissions inspection.

Now the muffler. Its main job is to quiet engine noises. Mufflers work by either absorbing or baffling sound. And you can actually customize your car's sound with different mufflers - anything from whisper quiet to bad-boy rumbley. Rusted or road-damaged mufflers can leak and need to be replaced right away. Talk to your friendly and knowledgeable service advisor at Car Doc On The Island .

The exhaust system is attached to the vehicle by a series of hangers and clamps. These fasteners hold the system in place. When hangers come loose or break, hot exhaust components can touch and melt wires, hoses and lines.

Finally, we end at the tailpipe. This is the final outlet for the exhaust. These can be plain-Jane or pretty flashy. Also, the oxygen sensors monitor the oxygen content of the exhaust so the engine control computer can adjust the fuel-to-air mix to keep the car running right.

Exhaust and emissions service at Car Doc On The Island in Venice covers plain old pipes and high-tech computers. It impacts everything from life-and-death safety due to exhaust leaks to fine-tuning the sound of your ride.

Which Item Is Most Stolen from Vehicles in Venice?

Which item is most often stolen from vehicles in Venice?

Is it:

1. Stereo
2. Wheels
3. Air Bag
4. DVD System

Well, if you said stereo – you used to be right. But airbags have now surpassed stereos as the biggest target for theft in FL – approximately 50,000 a year are stolen across the country. New airbags cost about $1,000, but go for $50 to $200 on the black market in FL.

Stolen airbags are making their way back into cars that have been in an accident. Of course, the danger to the consumer of having a stolen airbag installed is that you can never be sure what may have previously affected them and if they will work right when you need them.

Contact us at Car Doc On The Island for more information about where to get your airbags checked or replaced.

There are reports that 1 in 25 airbag replacements are stolen or salvaged airbags – or no airbag is installed at all.

That is definitely one car part you don't want to take a chance with, so Car Doc On The Island recommends following these guidelines:

• Use a reputable collision repair center that employs ASE certified mechanics (we can offer recommendations at Car Doc On The Island).

• Inspect the invoice to ensure that the repair shop purchased the airbag from a manufacturer, dealer or recycler. If you can inspect the airbag prior to installation, it should be packaged in a sealed container from the manufacturer.

• You will see the SRS light (Supplemental Restraint System) when you first start your vehicle up. This tells you that the airbag system is activated. If you do not see the SRS light, there is likely a problem with the airbag system.

Taking the Heat (Batteries in Hot Weather)

Quick question.  Which is tougher on a vehicle's battery, the heat or the cold? Believe it or not, it's the heat.  Think about it.  The battery often sits in the engine compartment next to that motor generating lots of heat.  That can accelerate corrosion in the battery and may even cause water in it to evaporate.  That will weaken the cranking power of your battery and shorten its life span.

To take care of your battery, here are a few suggestions.  It's a good idea to have it checked out to see what shape it's in.  At your vehicle service facility, they have diagnostic equipment that can evaluate its condition.  That can help you know how long you can expect it to last before having to replace it.  At the same time, you should have your charging system evaluated.  If your battery is not getting charged properly, it can be in great shape but not very useful when it comes to starting your vehicle.  A technician will also check the cable connections that should be free of corrosion and tight.

Keep in mind that under certain conditions, a vehicle battery can cause an explosion if close to an electrical spark.  This is why the safe way to go is to have a qualified, trained technician do the work. 

Your battery is important both in hot and cold weather.  When it comes to starting your vehicle, make sure it's always up to the job.

Not-So-Common Sense (Sensor Failures)

So your vehicle won't start.  What's the first thing that comes to mind?  Battery dead? Starter motor worn out? Out of gas?  Well, those are all reasons that make sense.  But your vehicle may be refusing to start because one of its computers is being warned that to do so might damage it.  Here's how that works.

You have lots of computers in your vehicle.  They need to know the status of things so there are several sensors monitoring various things going on.  These sensors send information to the computers that adjust the fuel and air mixture so you don't waste fuel.  They know when things aren't quite right and prevent you from starting your engine if that's going to damage it. 

Other sensors make sure the coolant is the right temperature, check to see you are not polluting the air and make sure other electronic components are performing their tasks correctly.

Here's an example of a sensor doing its job.  Your engine needs oil to lubricate metal components so the friction doesn't damage them.  Your engine has an oil pressure sensor that tells a computer called the Electronic Control Unit (ECU) if things are good to go or if there's something wrong, maybe the oil pressure is too low to keep things lubricated.  If it is, it gives a signal for the vehicle not to start, protecting the engine. 

Of course, the sensors can go bad, too, with some of the same results.  And so someone has to figure out if it's the sensor that's failed or if it really has detected a problem.  That is the challenge for technicians with specialized equipment to decipher the signs.  If a bad sensor is found, it may need to be replaced.  Sometimes a thorough cleaning can do the trick.  In either case, your service facility can track down the problem and get you back on the road.  Makes sense, doesn't it?
