Automotive Cooling System

The cooling system in your car works to keep your engine from overheating, and that is a very important job. If your vehicle overheats, it can mean the death of your engine.

If steam starts coming from under the hood of your car, turn off the air conditioner, open your windows, and turn your heater on wide open. This will help draw some heat from your engine though unfortunately, it will draw it into your car.

You do not want your vehicle to overheat, so if a service station isn’t in sight and the other measures didn’t work, you need to pull over and shut off the engine immediately.

Here are some reasons your car may get hot:

• Leak in your cooling system
• Thermostat problem
• Fan belt is loose
• Water pump problem
• Low oil level
• Bad hose
• Dirty radiator plugged with debris
• Timing needs adjusting
• Needs coolant

Actually, there are two types of cooling systems found on motor vehicles: Liquid cooled and Air cooled. Air cooled engines are found on a few older cars while modern vehicles use liquid cooling.

The Components of a Cooling System:

• The Radiator
• Radiator Cooling Fans
• Pressure Cap & Reserve Tank
• Water Pump
• Thermostat
• Bypass System
• Freeze Plugs
• Head Gaskets & Intake Manifold Gaskets
• Heater Core
• Hoses

CV Joint Repair

By regularly using a good service centre with certified technicians, a damaged boot will probably be detected before too much damage occurs. In this case, the technician will repack the joint with new lubricant and replace the boot.

The parts might not be too expensive, but the repair requires a significant amount of work, so you’ll end up paying a few hundred dollars to replace the boot. However, if you wait too long, you might need to replace the entire CV joint or maybe even the drive shaft, a much more expensive repair.

Unless you are an experienced mechanic, you probably shouldn’t consider joint repacking/boot replacement a DIY job.

A worn-out CV joint must be replaced – it can’t be repaired. You might be able to get hold of a reconditioned joint, but most likely you’ll end up with a new one.

You want the service center to ensure it is using the proper part for your vehicle and one that meets the OEM specifications. Cheap parts are a false economy, and should always be avoided.

Common CV Joint Problems

For smooth running, a CV joint uses a special lubricant that is packed in and then sealed by plastic or rubber boot secured with a pair of clamps. As long as that boot is undamaged, the CV joint should last a long time without maintenance.

It is more likely that your car will rust through before the CV joint goes. However, a damaged or cracked protective boot opens up a whole world of pain as lubricant spills out and water infiltrates the joint.

This causes the CV joint to corrode and fail. Outer boots seem to be the more vulnerable ones, probably because they must withstand more motion than do the inner boots.

A properly trained and certified technician will inspect your CV boots for tears, cracks and other damage whenever you bring your vehicle in for scheduled care.

Transmission Repairs Brisbane

A transmission system in which the gears are operated by the driver by means of a stick shift and clutch pedal. Manual transmissions are generally preferred for high-performance driving, or as a lower-cost alternative to more expensive automatic transmissions. They are also simpler, and less costly to repair as well.

Transmission Components

The modern automatic transmission consists of many components and systems that are designed to work together in a symphony of clever mechanical, hydraulic and electrical technology that has evolved over the years into what many mechanically inclined individuals consider to be an art form. We try to use simple, generic explanations where possible to describe these systems but, due to the complexity of some of these components, you may have to use some mental gymnastics to visualize their operation.

The main components that make up an automatic transmission include:

• Planetary Gear Sets which are the mechanical systems that provide the various forward gear ratios as well as reverse.

• The Hydraulic System which uses a special transmission fluid sent under pressure by an Oil Pump through the Valve Body to control the Clutches and the Bands in order to control the planetary gear sets.

• Seals and Gaskets are used to keep the oil where it is supposed to be and prevent it from leaking out.

• The Torque Converter which acts like a clutch to allow the vehicle to come to a stop in gear while the engine is still running.

• The Governor and the Modulator or Throttle Cable that monitor speed and throttle position in order to determine when to shift.

• On newer vehicles, shift points are controlled by Computer which directs electrical solenoids to shift oil flow to the appropriate component at the right instant.

Automotive Engine Repairs

Automotive engine repairs and engine replacement might be very expensive, so it is advisable to understand the varied components of your car and educate yourself in regards to the engine necessities to keep away from untimely repair and engine substitute of your car. The automobile engine, brakes and brake liners endure innumerable put on and tear and usually break down simply, so it’s essential look out for his or her upkeep frequently and preserve yourself up to date about your automobile health.

It is best to regularly put your automobile for engine tune up and examine the ignition system and emission controls of your car, in order that the motors of your automobile remains in healthy condition and your automotive engine runs easily for an extended time. Nevertheless, ultimately, problems would come up and also you will surely need to switch sure parts of the ignition system such because the contact breaker and distributor cap or rotor button.

Adjustments in the cylinder head bolts and the substitute of filters and spark plugs can also be necessary, so you need to verify along with your automobile mechanic to find out extra about your automobile engine and usually change parts which are worn out.

New automobiles don’t want common engine tune-ups and may run easily for years without replacement or repairing, however, it’s essential to not take any possibilities and usually send your automotive for servicing.

At times, even with correct engine tune ups, you would find that your automobile engine is wearing down and will even breakdown eventually. When this happens, you would have to decide about both replacing your automobile engine or repairing it to tug on for a few extra years

Fuel Injection System

The fuel that powers you down the road. The fuel system is critical in storing and delivering the gasoline or diesel fuel to your engine. Typical components are the fuel filter, fuel pump and fuel lines. Read more below to find out how it all works.

The fuel system feed your engine the gasoline/diesel it needs to run. If anyone of the parts in the system break down your engine will not run.

Let’s look at the major parts of the fuel system,

• Fuel tank: Basically a holding tank for your fuel. When you fill up at a gas station the gas travels down the filler tube and into the tank. In the tank there is a sending unit which tells the gas gauge how much gas is in the tank.

• Fuel pump: On newer cars the fuel pump is usually installed in the fuel tank. Older cars have the fuel pump attached to the engine or on the frame rail between the tank and the engine. If the pump is in the tank or on the frame rail then it is electric and is run by your cars battery. Fuel pumps mounted to the engine use the motion of the engine to pump the fuel

• Fuel filter: Clean fuel is critical to engine life and performance. Fuel injectors have tiny openings which clog easily so filtering the fuel is the only way to prevent this. Filters can be before or after the fuel pump, sometimes both.

• Fuel injectors: Most domestic cars after 1986 and earlier foreign cars came from the factory with fuel injection. Instead of a carburetor to mix the fuel and air, a computer controls when the fuel injectors open to let fuel into the engine. This has resulted in lower emissions and better fuel economy. The fuel injector is basically a tiny electric valve which opens and closes with an electric signal. In the picture below you can see the injectors towards the outer part of the intake. By injecting the fuel close to the cylinder head the fuel stays atomized ( in tiny particles ) so it will burn better when ignited by the spark plug.

• Carburetors: A carburetor take the fuel and mixes it with air without computer intervention. While simple in operation, they tend to need frequent tuning and rebuilding. This is why most newer cars have done away with carburetors in favor of fuel injection.
