Almost all automotive engines require a circulating liquid to remove the excess heat. Although water is an effective heat transfer liquid it has major shortcomings to become an engine coolant
- •It boils at a very low temperature ( 100°c )
- •It freezes also at relatively high temperature ( 0°c )
- •It is highly corrosive and damages all engine metals especially alluminium when at high temperature.
These problems make it imperative to use proper Antifreeze coolant in engine cooling system for a complete trouble free operation of the vehicle.
Purpose : The combustion of fuel and air inside the engine produces enormous heat, only a part of which is converted to mechanical energy to drive the vehicle and the rest is left to engine body and exhaust for removal. High speed driving of today’s engine can produce enough heat to melt an average engine in 20 minutes. All other parts of the engine also may run at very high temperature, much above the normal boiling temperature of water. The purpose of automotive engine cooling system is to control the engine< metal temperature within safe limits by removing excess heat produced by the combustion. When metal temperatures are not controlled by adequate cooling the consequences are lubrication failure and serious engine damage.
The enormous heat generated in combustion chamber utilizes only one-third of it to convert into mechanical energy for driving the vehicle, one-third is removed through exhaust gas and the remaining one-third is released to the engine body which eventually heats up the vehicle. The liquid cooling medium flowing through the cooling system absorbs this heat and dissipates to the atmosphere through radiator.
The popular belief of usefulness of coolant is :
Liquid when mixed with water and used in automotive cooling system, prevents overheating of the engine. In olden time's this definition was fairly adequate.
The present days’ automotive engines, however, demand much more from Coolant. The chemistry or technology of antifreeze coolant has therefore undergone a sea change with the continuous improvement & modernization of automotive engineering.
Golden Cruiser has always been the pioneer & in the forefront of such technological evolutions in antifreeze coolant chemistry worldwide.
Although water is a very good medium for cooling, it has many serious shortcomings which does not make it suitable for as a coolant for engines.
Antifreeze Coolant is therefore used in combination with water as engine cooling medium which not only overcome all the demerits of using only water but also makes the system efficient and long lasting.
The basic functions of Antifreeze Coolants are as follows:
- •Protection from Boiling and Freezing of cooling medium.
- •Effective Transfer of heat
- •Protection from Rust and Corrosion
- •Lubrication of Water pump
- •Compatibility with hard water
- •Non foaming and Less evaporating
- •Compatibility with Plastics, Rubber, Paint and other cooling system materials
- •Chemical Stability at low and high temperature.
- •Low ecological and toxicological hazard for the environment
Whereas, the functions like Boiling point, Freezing point, Foaming, Evaporation and Water miscibility are the inherent properties of conventional antifreeze coolants, the main stress of performance efficiency came on :
- •Effective High temperature Stability
- •Protection from Rust & Corrosion
- •Effective transfer of Heat
- •Chemical stability / longevity aspects of the system.
The Golden Cruiser range of Brake Fluids are hydraulic fluids whose main purpose is to transfer force into pressure and amplify braking force .Golden Cruiser Brake Fluids are manufactured primarily using glycol ethers and patented corrosion inhibitors.
The Brake Fluids currently available in the market generally conform to D.O T (Department Of Transportation, U.S.A) 3 & 4 or SAE (Society of Automotive Engineers) J 1703 & J 1704 Specifications. These specifications provide for a minimum requirement for critical parameters such as Boiling Point, Wet Boiling Point, Viscosity, and Corrosion Protection among others.
Automakers however specify much more stringent specifications than those laid down by the above organizations. Golden Cruiser Brake Fluids meet and exceed the specifications laid down by these automakers .It is a testament to the quality and performance of Golden Cruiser Brake Fluids that Golden Cruiser Brake Fluids are used exclusively By Maruti Suzuki, Nissan, Toyota, Mercedes, Honda among others as their original fill in India. Globally 25 % of the vehicles manufactured come factory filled with Golden Cruiser Brake Fluids.
The main distinction between Golden Cruiser Brake Fluids and other available in the market are their very high boiling point and their wet boiling point (when the brake fluid naturally absorbs water during usage). These two properties ensure that there is there is no possibility of the brake failure due to the fluid boiling over.
Golden Cruiser Brake Fluids are manufactured using patented corrosion inhibitors which protect the metal and rubber parts of the braking system thereby preventing any possibility of brake fluid leakage from the system. Unlike other brake fluids available in the Indian market Golden Cruiser Brake Fluids are low viscosity fluids which can operate in extreme temperatures and are capable of good conductivity required of such brake fluids.
Brake Fluids are required to be changed every 2 years. In India however it is one of the most neglected components of the vehicle resulting in many avoidable accidents.
Given below are some of the critical parameters which brake fluids are supposed to meet. alongside the typical results for Golden Cruiser Brake Fluids are also provided .
It can be seen that Golden Cruiser Brake Fluids are far superior than others Brake Fluids available in the market.
