- What is VR-12 and how it Works?
- VR-12 is a concentrate of organic chemical components, mixed through a synergetic process, whose cutting edge design and conservationist concept, have created a product that protects your vehicle’s cooling system, and saves you money, while you preserve the planet. For more information see the following explanatory video.
- When and how to use VR-12?
- - On every oil change
- After a flush.
- For topping off use a bottle of VR-12 and complete fill with water or the product of your choice.
- Recommendation for maintenance of the antifreeze, coolant and water use VR-12 every 6 to 9 months.
- One bottle of VR-12 will protect 3 gallons of any fluid in the cooling system.
- How to diagnose problems in a car's cooling system?
- You pull up to a traffic light and see steam coming from under the hood of your vehicle. Now the coolant temp light has come on. Perhaps you are driving down the road in cooler weather and you note that the car seems to be using more gasoline and the heater does not work. Both of these scenarios are systematic of cooling problems. The good news is that it does not take a trained mechanic or special tools to diagnose a cooling system problem and it only takes an hour or so to check it out. For more information see the following explanatory video.
- How the correct maintenance of the car’s cooling system contributes to protect the environment?
- Your vehicle’s cooling system is vital to the operation of your vehicle. Driving at freeway speeds and hot summer days put a lot of stress on your vehicle’s cooling system. Basic checks can assist in maintaining your vehicle’s cooling system. For more information see the following explanatory video.
- What are the consequences of engine overheating and its associated costs?
- If your car’s cooling system is not working properly, heat can destroy your car’s engine. If you notice your car starting to overheat, the following explanatory video can help you to prevent harm to your vehicle.
- How a car’s radiator works, which are the most common faults are and how to avoid them?
- A radiator is a type of heat exchanger. It is designed to transfer heat from the hot coolant that flows through it to the air blown through it by the fan. Most modern cars use aluminum radiators. These radiators are made by brazing thin aluminum fins to flattened aluminum tubes. The coolant flows from the inlet to the outlet through many tubes mounted in a parallel arrangement. The fins conduct the heat from the tubes and transfer it to the air flowing through the radiator. For more information see the following explanatory video.
- Do I need to do flushing?
- Maybe you’ve taken your car in for some recent service and the mechanic let you know you needed a cooling system flush.Or perhaps you noticed your vehicle was a little low on coolant and when you went to top it off you noticed some gunk floating in the overflow tank or radiator. These all are good indications that it may indeed by time for a radiator flush, or more accurately a cooling system flush. For more information see the following explanatory video.
- What are electrolysis and oxidation and how do they affects the engine's proper functioning?
- If dirty or mineral-rich water is used in a cooling system, you can quickly accumulate scaling and sediment build-up on the interior of your radiator.
Electrolysis is the process by which this accumulation occurs. This build-up can be cleaned out with radiator cleaners and, for some radiators, with a rod and brush. For more information see the following explanatory video.
- What is the water pump and how do I keep it from failing?
- The water pump is a simple centrifugal pump driven by a belt connected to the crankshaft of the engine. The pump circulates fluid whenever the engine is running. The water pump uses centrifugal force to send fluid to the outside while it spins, causing fluid to be drawn from the center continuously.The inlet to the pump is located near the center so that fluid returning from the radiator hits the pump vanes.
The pump vanes fling the fluid to the outside of the pump, where it can enter the engine.
The fluid leaving the pump flows first through the engine block and cylinder head, then into the radiator and finally back to the pump. For more information see the following explanatory video.
- Should I remove the thermostat to keep my car cool?
- The thermostat’s main job is to allow the engine to heat up quickly, and then to keep the engine at a constant temperature. It does this by regulating the amount of water that goes through the radiator.
At low temperatures, the outlet to the radiator is completely blocked, all of the coolant is recirculated back through the engine. For more information see the following explanatory video.
- What are the cooling system's hoses: materials, types, possible failures and how to avoid them?
- On most vehicles there are two radiator hoses. A top radiator hose is attached to the thermostat housing, which allows the heated coolant to enter the top or inlet side of the radiator.The bottom or lower radiator hose is connected between the outlet of the radiator and the inlet of the water pump.
The heater hoses are normally pre-shaped for the particular make and model of vehicle you are servicing.The construction of the heater hose is the same as the radiator hose, with a reinforcing material embedded into it. The hot coolant comes in through the hose attached to the thermostat circuit, and as it sheds some of its heat into the vehicle, it cools down and returns to the engine via the water pump inlet. For more information see the following explanatory video.
- What coolant is, why it’s necessary, how it’s made, maintenance and environmental hazards?
- The cooling system on liquid-cooled cars circulates a fluid through pipes and passageways in the engine. As this liquid passes through the hot engine it absorbs heat, cooling the engine. After the fluid leaves the engine, it passes through a heat exchanger, or radiator, which transfers the heat from the fluid to the air blowing through the exchanger. For more information see the following explanatory video.
- Can I use tap water into the radiator?
- The difference between using the proper mix of coolant or just using tap water is huge. The most obvious difference is the freezing point. Tap water’s freezing point lies at 32º F and coolant’s freezing point is a lot lower.
If you live in a cold climate and use tap water inside your car’s cooling system, you can cause damage because water freezes and expands which can crack your engine block, radiator and other system components. For more information see the following explanatory video.
- How to transform Tap water into radiator water?
- In race cars everything changes regarding the use of coolant, some race tracks do not allow the use of ethylene glycol-based coolants because they can be very slippery if spilled on the racing surface. You’ll be forced to use only water as coolant.
Fortunately, the use of water to cool racing engines is not entirely harmful. For more information see the following explanatory video.
- How can I keep the cooling system in good condition?
- The engine is a controlled explosion system, that needs to run in a specific temperature range, to operate correctly. This is very important for todays electronically controlled emission engines in order to maintain peak performance, maintain fuel mileage and emission standards. For more information see the following explanatory video.
- What should I do if my engine overheat?
- No matter how modern or reliable your car is, engine overheating on the road isn’t an uncommon occurrence.
Excessive heat can completely destroy your engine, therefore…
…if you are driving your car and note that:
- the temperature gauge is high,
- the temperature light is on,
- Steam coming from under the hood and
- Unusual noise,
Then you are facing engine overheating.
In this situation, see the following explanatory video for what to do.
