    Holden In the latter models of the Holden Commodore the Echotech engine was substituted for the Alloytech. For many reasons this engine was mechanically problematic, one such issue was the placement of the thermostat.

    The Thermostat is a component that requires replacement semi regularly. What would normally be a simple job in most cars is a nightmare in the Alloytechs. The Thermostat is located on the back of the motor. A position that makes no sense until you discover that the motor was originally designed for front wheel drive east west mounted vehicles.

    There are several methods to getting to this component and all of them are about as much fun as a Jehovahs Witness themed fancy dress party. Most advise removal of the transmission and whilst this sounds like an excessive amount of work it is probably the easiest method to approach this job. Once the transmission is out the job is a piece of cake. The second choice in the list is the removal of the top half of the inlet manifold.

    To do it this way you still require small hands and lots of patience. We have once gotten away with doing this by removing the rear transmission mount, bracing the transmission and pushing the transmission to the side and getting your hands up between the transmission tunnel and the gearbox but the time involved to do this, it would have been quicker to remove the transmission. Some have gotten away without any of these such methods and just got hands in there to do it.

    Is beyond us but it can be done. It is strongly recommended that genuine parts be used for this job. The pipes coming out of the housing are sealed with O rings that if not the correct size down to thousands of an inch will more than likely leak.

    We advise buying the genuine housing, thermostat and O rings. Whilst doing this job we also strongly recommend you carry out a cooling system flush and changing the coolant from the factory red to green coolant.

    Make sure a full flush is done including the heater core. We have found the red coolants are more prone to leaking than the green ones. Browse more blogs on our website www.

    And this is one of the most common problems that every car owner in Australia faces — the fluid leak. A tiny little spot under your car may be trying to tell you something. Any car leaking fluid can lead to expensive car repairs and dangerous situations or accidents if the problem not sanitized in time.

    There are many different types of fluids which find use in your car. Fortunately, the car fluids differ in colour, texture and smell. With little knowledge and understanding about the car fluids, finding the source and the cause for the fluid leak will be much easier.

    Here are some of the most common fluid leaks and how to identify them. Oil Leaks Oil is definitely the most common fluid that you will find under your car. Unused oil usually has a gold colour, but this depends on the brand. Some oil brands feature a dark amber colour like a light beer. The texture of the oil is quite slippery, and it is quiet difficult to remove it from your hands with water only. Soap or other cleaning solution is necessary. The motor oil gets very dark when it is in the engine for a quite long time, because it collects all the debris and unburned gases from the engine.

    Motor oil smells like cooking spray or burnt butter. It gets extremely hot which is why it gets that burnt smell with a little hint of fuel. The most common areas for oil leaks are the timing covers, the valve cover gaskets, the oil drain bolts and the oil filters. If you notice oil leaks under your car, place a cardboard under the car in order to identify the leaking area.

    It is always recommended to visit your local mechanic workshop to fix the oil leak on time. Automatic Transmission Fluid Leaks The automatic transmission generally uses red or pink fluid. If it is very old, the automatic transmission fluid turns into brown and dark gray colour. The texture of the transmission fluid is similar to the motor oil, and it smells like cooking oil. A sign that you might have transmission fluid leaks is when the transmission starts to slip and eventually the car stops moving.

    Again, you can place a cardboard under your car to identify the leaking areas. The most common areas for transmission fluid leaks are the axle seals and the output shaft seals. This depends whether the car is using front wheel drive system or a rear wheel drive system. If you notice a red or pink fluid under your car, remove the transmission dipstick and check the level of the transmission fluid, or go to your local mechanic to identify the cause for the transmission fluid leak.

    Brake Fluid Leaks The brake fluid is clear and usually has a light yellow colour with dull mechanical smell. The brake fluid is described as highly corrosive to paint.

    If you ever pour a brake fluid on your car paint you need to quickly wash it with a window cleaner. This way, you will neutralize the corrosive elements in the brake fluid. When the brake fluid is not changed for a long period, it gets green because it collects the moisture from the brake fluid reservoir. The areas for brake fluid leaks are the master cylinders and the flex lines. If the master cylinders are leaking brake fluid, it will usually appear near the brake pedal.

    If the flex line leaks it will appear near the wheels. If you notice signs of brake fluid leak, act quickly! Visit your local mechanic and resolve this problem immediately. Power Steering Fluid Leaks Some cars use transmission fluid as power steering fluid, but you can also buy special power steering fluid for your car.

    This fluid has light yellow colour and medium thickness. It has a unique smell which cannot be compared with other fluids. Most closely it has some kind of burnt smell. The most common areas for power steering fluid leaks if you have rack and pinon steering are the ends of the steering rack, and the rack end seals. If your car has steering gear box, the power steering fluid leaks would appear at the bottom of the seal of the steering gear box.

    If you notice power steering leaks, check the steering rack boots and see if they are wet. If they are, this may be a sign that you need to replace the entire steering rack. Differential Fluid Leaks The differential fluid is very thick lubricant used in cars. It has strong and stinky smell, and if your hands get dirty with differential fluid, they will smell for days. The differential fluid has a colour of honey, but it tends to get gray because it absorbs metal dust when the gears are meshing.

    The most common areas for differential fluid leaks would be the pinon seal and the axle seals. If the axle seals are leaking, you will most likely see spots at the hub area close to the wheel area. If the pinon seal is leaking, you will see spots at the u-joint near the differential. Coolant Leaks Coolant fluid leaks are most likely the second most common right after the motor oil leaks.

    This fluid can either be green or pink, but most commonly it comes in green colour. It has sweet smell and it is highly viscous. Usually, coolant leaks appear beneath the radiator or near the front end of the engine. Coolant leeks can be very dangerous because they can cause engine overheating. Ensure you sanitize the problem in time to prevent future costly repairs.

    How to Change the Thermostat in a Holden Commodore Alloytech V6

Once the transmission is out the job is a piece of cake. The second choice in the list is the removal of the top half of the inlet manifold. To do it this way you still require small hands and lots of patience. Usually, some amount of water will come out of suspension and form white gummy masses in various areas of the unit.

    This is why the unit cannot be flushed to remove all of the water.

    In addition, the presence of water will start rust forming on the ferrous metal parts throughout the unit. The amount of water and the length of time that it is inside of the unit will determine the extent of the damage, but the resolve to the problem will be to overhaul the transmission. How does water get into the transmission? There are plenty of ways for water to find its way into the transmission. Figuring out where the water came from is tricky. Water can come from the radiator or an external source.

    All transmissions have a cooling line that runs to the radiator. A separate fluid passage circulates the transmission fluid through a portion of the radiator to cool the fluid. The brake fluid is described as highly corrosive to paint. If you ever pour a brake fluid on your car paint you need to quickly wash it with a window cleaner.

    This way, you will neutralize the corrosive elements in the brake fluid. When the brake fluid is not changed for a long period, it gets green because it collects the moisture from the brake fluid reservoir.
