Heater Core Info

 

Many people driving around Costa Mesa have never even heard the term “heater core”. You might wonder what a heater core is. To put it simply, it is part of your car’s cooling system. It looks like a miniature version of your radiator, and functions like a small radiator itself. It is responsible for the function of your climate control system’s heater and defroster.

Your heater core works by circulating coolant through tubes within it. The coolant comes in through one heater hose and out of the other, radiating heat into your cabin through the air vents. It is connected to the air conditioning system. In most cars, heater cores are behind the dashboard, under the center or passenger side. They usually are contained in some sort of case or housing, and are not very easy to get to.

Do New Vehicles Still Have Spark Plugs?

 

Spark plug - the name itself is pretty self explanatory. To put it simply, your vehicle’s spark plugs are parts that plug into the top of your engine’s cylinders and create a spark which ignites the air and fuel mixture inside to start the engine and keep it generating power. The number of spark plugs in your car’s engine is usually the same as the number of cylinders, although some automakers will use two spark plugs per cylinder. 

Spark plugs are responsible for igniting the fuel that your engine needs to run. When you turn your key, a small amount of electricity is sent to the ignition coil, which transforms it into a high voltage current, which travels through your ignition cables to your spark plugs and create a spark, igniting the fuel. If your spark plugs malfunction, they will not be able to create this spark and ignite your fuel, causing your engine to run poorly or not at all. If you continue to drive your vehicle with malfunctioning spark plugs, it may also cause damage to your catalytic converter due to unburnt fuel and more particulates in your exhaust gases.

Fuel Pump Repair and What it's For

You probably already know that your vehicle’s gas tank is most likely several feet away from its engine. You may have also heard that the Ford Model T had a gravity-fed fuel system, which would result in owners having to drive backwards up hills to prevent the engine from becoming starved of fuel and stalling. Of course, today’s cars are much more advanced - they use a component known as the fuel pump to keep gasoline flowing into your engine. If your car stalls out nowadays and there aren’t any mechanical problems with it, you’re probably just out of gas, no matter how steep of a hill you’re driving up.

There are several ways you can tell if your fuel pump may be going out. Some of the most common symptoms are your vehicle hesitating to start, loss of power or stuttering during acceleration, a whining sound, and an illuminated check engine light.

Rack and Pinion Steering

Most vehicles have a steering system that consists of a rack and pinion. The rack and pinion is the part that converts the rotational movement of your steering wheel into the left and right motion of your car’s front wheels. It works by a pinion gear on the end of the steering shaft, which moves along teeth on a horizontal rack. Rack and pinion systems have a simple design, and are usually not too hard to repair if any issues arise.

The first sign of an issue with your rack and pinion system is often a change in the way your vehicle feels as you drive. The steering wheel may feel loose or start sticking at certain points while you turn, or your steering wheel may pull to one side even while you're driving down a straight, level road. There are several parts of your steering system that may wear out and cause issues with your rack and pinion, including the ball joints, control arms, tie rods, coupler, knuckle, and pump.

Keeping You And Your Engine Cooler

This week on ExperTec Costa Mesa’s Cars 101 Blog, we’re keeping you and your engine cool. We’re gonna cover your vehicle’s engine’s cooling system, how it works, and the reasons why it might need some work.

Coolant, also widely known as antifreeze, is essentially the fluid responsible for absorbing and dissipating heat from the engine by flowing through passages within the engine, then out of the engine and through the radiator, where it is cooled off by fast-flowing air going through your grille and is cycled back into the engine again. It is made from a mixture of either ethylene or propylene glycol and water, usually in a 1:1 ratio. Coolant service means draining and flushing your car’s cooling system, then refilling it with new coolant.
