No Fuel-ing! (Fuel Filter Replacement)

Your vehicle has a few filters you might be somewhat familiar with.  There’s the oil filter that removes impurities from your engine’s oil, and a couple of different kinds of air filters that prevent contaminants from getting into the engine and the cabin. But you may not know that your vehicle also has a fuel filter.

The fuel filter keeps contaminants such as particles and other foreign substances from making their way into the engine.  They can result from using lower quality fuel, driving in dirty or stop-and-go conditions, or simply what happens after many weeks and months of travel. 

At some point, your fuel filter will start to get clogged up and won’t let the fuel get to your engine easily.  You might notice some signs of that: your engine doesn’t have the power it used to, it may misfire when you accelerate, it may be harder to start, or it may stall while you’re driving.  You may notice your vehicle vibrating a lot when you’re idling.  

If you notice any of those symptoms in your vehicle, you should bring it in for us to take a look.  We can run diagnostics such as a fuel pressure test that will let us know if your fuel filter is finished or still has a little more life remaining.

Even better, it’s a good idea to replace the fuel filter BEFORE you start seeing symptoms.  Each vehicle’s manufacturer recommends an interval at which you should change your fuel filter.  Older vehicles may recommend it be changed fairly frequently, such as every 30,000 miles/50,000 km.  Newer vehicles from different manufacturers have much longer intervals, and that’s something we can check so you can stay on schedule with regular maintenance.  

Make sure your fuel filter is doing its job so your engine can keep doing its job.

Power Steering Pump Replacement

When you’re driving and you hear a squeal or groan when you turn, it may be a sign your power steering pump is on its last legs.  The same is true if you feel your steering is slipping or doesn’t respond to your hands like it used to.  

Precise, responsive steering is, of course, important when it comes to safe driving, so this is something you should have one of our technicians look at sooner rather than later.  

There are different types of power steering pumps, and they all perform a similar function.  They make it easier for you to turn the steering wheel with little effort as the power steering system multiplies that force so you can precisely aim a vehicle that weighs thousands of pounds.  

The type of power steering pump your vehicle has depends on the power steering system it uses.  One works by hydraulics, taking energy provided by belts driven by the engine which pressurizes power steering fluid to the wheels.  There are a lot of components in these systems, and they can wear out more quickly than some other systems.

Another power steering system works on electricity, which is more fuel efficient and produces fewer emissions.  It works on electrical power created by the vehicle’s electrical system and doesn’t put as much of a load on the engine.  With electric power steering systems, your vehicle can change how the steering feels or responds in different driving conditions.

When your power steering system isn’t working correctly, a technician will determine where the problems are.  Not only could it be the power steering pump, but there are several other parts that may be contributing to your steering issues.  That may include leaks in hoses and seals, faulty belts and corrosion in electrical components and connections. 

When you feel the steering in your vehicle doesn’t have the solid, smooth silent response it used to have, bring it in so a technician can diagnose the problems and steer you back in the right direction.

You Are the Fluid Detective! (Leaking Fluids)

When you see some liquid sitting underneath your vehicle, your mind starts churning.  Is that normal? Is that something serious, or did I just spill my drink? Here’s a quick list of what those fluids look, smell and feel like, as well as what they might be. No, we don’t recommend you taste them to verify.

   •    Clear and underneath your air conditioner or under the end of your tailpipe. It’s likely something as simple as condensed water.  This probably doesn’t need immediate attention, but you should keep checking periodically.
   •    Oily, brown, golden or black.  That could be the sign of engine oil leaking.  Oil may also smell if it has been leaking on metal and burning.  This is one you should have checked out fairly quickly.
   •    Green, blue, red, yellow, purple or orange and watery under the engine.  Smells sweet.  May be coolant (antifreeze) and a sign of a leaking radiator, hose or clamp.  Also, could mean your water pump is shot or radiator is broken or cracked.  The more that’s there, the more important it is for us to check it out soon.
   •    Yellow, slippery and smells a little foul.  Could be brake fluid. This is one that you should bring to us quickly to have us inspect.
   •    Red or pinkish and collects under the engine or middle of your vehicle.  Could be power steering fluid.  Here’s another one that should be checked by a professional soon.
   •    Red or brown liquid from around your transmission or between your radiator and the transmission, smells sweet.  You might smell burning from around your engine area, too.  Might be transmission fluid.  Another one where it’s important to have a pro look at it soon.  

Your eyes and nose can be helpful to spotting things that need attention on your vehicle.  When in doubt, head on over to see us so a technician can check it out.  Taking care of it sooner rather than later could save you an expensive repair down the road.

In the Red (Why a Vehicle Overheats)

Heat is one thing that can damage a vehicle, especially if a problem isn’t taken care of soon.  Be on the lookout for signs that it’s getting too hot in some parts of your vehicle, starting with the most obvious one: the heat gauge/warning light on your instrument panel.

When you see that heat gauge heading into the H zone or the warning light comes on, it’s often because your engine’s coolant is contaminated or running low.  It’s important to let a pro look at it soon before serious damage is done,

The radiator is another trouble spot that can cause overheating.  It has a fan that needs to run properly, and it needs to be free of debris and dirt. Another radiator trouble spot is the core.  When it gets clogged and coolant isn’t circulating as it should, an overheated engine can be the result. Have your cooling system checked regularly, including its thermostat.

Your water pump is another part of the cooling system that can wear out, and when it’s not working right, your engine can get hot quickly.  It should also be on the list of regularly checked engine components.

Finally, your vehicle has several rubber belts and hoses that play vital roles in making sure the coolant is getting where it needs to be.  It’s important to have those inspected by a technician before they fail and heat starts to build up.

Your vehicle’s cooling system is complex and critical to its operation. Plus, it must be maintained so it does what a vehicle’s engineers designed it to do.  When it comes to your vehicle, cool is cool, hot is not.

Stop! And See Us (Brake Pad Replacement)

If you’ve ever driven a bicycle with hand brakes, you’ll probably understand how the brake pads on your vehicle work.  Bicycle brakes use a system that squeezes the bike wheel’s rim with a pair of cushioned pads activated by your hand squeezing the hand brakes on your handlebars. The friction of those pads stops the wheel.

That’s the same principle used for the wheels on your vehicle.  Step on the brake pedal and that causes pads to put pressure on discs in the wheels called rotors.  Those pads create friction and stop the wheels from turning.

Brake pads in vehicles are made from several different materials.  The pads most commonly used are ceramic or a combination of metals.

The friction that stops your vehicle generates heat and wears both the pads and, eventually, the rotors, too.  That means that, over time, both are going to need replacing to work properly.  One sign brake wear is getting noticeable may be  when you hear squeaking when you stop.  Or you might feel the vehicle pulling to one side during braking or the brake light on your dash illuminates.  All are signs to bring your vehicle in to us for inspection and service.

When your vehicle is in for brake pad replacement, our technician will check other components such as the brake calipers, rotors and lines.   

Brakes are something you should have inspected at regular intervals because they are a vital safety component of your vehicle.  Consider having us look at them every 10,000 miles/16,000 km or each time you bring your vehicle in for an oil change.
