Keeping Your Cool (Coolant System)

No matter what the weather is like outside, your internal combustion engine expects to keep its cool all the time, even when it's really cold.  That's because engines create the power that moves you to your destination by a series of tiny explosions of a fuel and air mixture. In turn, that generates a lot of heat in a small space.

Your vehicle has a complete cooling system with a lot of different parts that work together to keep the temperature at a point where the metal engine parts won't heat up enough to warp.  Its lifeblood is coolant, a liquid that circulates through the engine (and, in most vehicles, the transmission, too) through a series of hoses and tubes. 

In order to get rid of the coolant's heat, your vehicle has a part you probably recognize: the radiator.  It does what its name proclaims: radiates heat.  The radiator has a series of thin metal fins that coolant goes through, and when outside air passes over them, the heat is dissipated from the radiator into the air.

The water pump (which is technically a coolant pump) is what propels the coolant where it needs to go. 

When there's a problem in the coolant system, it may because it's leaking somewhere.  A few things to look out for are the temperature gauge heading into the hot, or red, zone, fluid leaks under your vehicle, or the sweet smell of coolant under your vehicle after it's been parked.

If your vehicle has any of those signs, bring it in so we can check things out.  A technician will inspect the water pump and hoses for any signs of leaks.  They'll also look for leaks or holes in the radiator core or cores. 

One other potential trouble spot is the radiator cap that can sometimes fail to keep the required pressure in the radiator.  Once the problems are fixed, they'll add the correct coolant and you'll be on your way.  We want you to always keep your cool.

For 4x4s (Maintenance of 4x4 Vehicles)

Some people love 4x4 vehicles, the true 4-wheel drive works of engineering like Jeeps and 4x4 pickups that allow you to seemingly go anywhere on the planet. You can climb up a 40-degree rock trail with some planning and skill (always careful to protect the environment, of course), or you can get through the deepest snow.

But with that added capability comes additional complexity, drive-train components and other systems that less capable vehicles don't have.  And that is why when it comes to 4x4s, you have to maintain them a little differently from those vehicles that spend their lives on pavement.  Here are some of the key things to keep an eye on:

• Transfer case—This transfers power from the engine to the wheels.  A transfer case has fluid in it that needs to be changed at intervals recommended by the manufacturer.  Your service advisor will let you know how often that is and will keep track of your service dates.  You will need to make sure the transfer case seal is working properly.  Otherwise, transmission fluid could get in and cause damage that is costly to fix.  Some transfer cases have an electric motor that shifts it through gears, and its connections are often exposed to the elements, making them vulnerable to damage and corrosion.  Proper maintenance will keep those connections working like they should
• Front and rear differentials—These also have to have the right amount of fluid and should be checked regularly.  Your service advisor can let you know when you need that fluid changed as the owner's manual recommends.  It's important the service is performed correctly with the proper lubricant so it will work the way it is designed to.
• Brake lines—Those 4x4s practically beg to go into wet spots. They also are great machines to conquer snow: road salt, brine and all.  Moisture, salt and brake lines are a recipe for corrosion, so brake lines need to be inspected regularly.  There are anti-corrosion sprays or white lithium grease that can retard corrosion.  Remember, getting there is half the fun, but not being able to stop is no fun at all.

So enjoy your 4x4 and what it can do that other vehicles can't.  Just remember that even though it's tough on the outside, it needs special care to keep it going.  Oh, and remember to take care of the environment when you go off-roading, too.
