Oil in Coolant Engine Oil Getting Mix With Coolant Engine Oil In Radiator Helpful Information These fluids may exchange places when these items fail due to pressures inside each system. Because engine and transmission oil pressure runs at about 40 psi and cooling system pressure runs about 18 psi oil is more likely to enter the coolant system rather than coolant entering the engine or transmission through the cooler. Step by step guide on how to troubleshoot and repair an automotive oil in coolant problem, this information pertains to most vehicles. Difficulty Scale: 4 of 10 Begin inspection with the vehicle on level ground, engine "OFF" and cooled off, in park with the emergency brake set. Step 1  - Many automotive engines utilize an oil cooler in which radiator coolant passes through to remove heat from the oil. When these coolers fail they allow engine oil to enter the cooling system and into the radiator. Oil Cooler Step 2  - To check for this condit...

Radiator Working Of Car Radiator Step by step guide on how an automotive radiator works, this information pertains to most cars. Helpful Information Radiators consist of a few basic parts, two tanks and the core. The radiator "tanks" located on the sides or top and bottom are used to attach upper and lower coolant hoses. Vehicles that have tow options will sometimes incorporate an engine oil cooler into the radiator to help keep the engine temperatures at a safe level. Radiators come with different amounts of these tubes or “rows” as they are called in the industry to support various applications. Old radiators are recycled cutting down on heavy metals and environmental impacts. History Through the years materials used in the construction of a radiator have changed dramatically. Older vehicles used a heavy brass construction, while newer vehicles use an aluminum core and plastic tanks. Brass radiators worked well for years, but material costs and the environme...

Cooling System Working Of Vehicles Cooling System Helpful Information The engine's combustion chamber can reach temperatures of up over four thousand degrees Fahrenheit. About thirty percent of the fuel is converted into actual power, and the remaining seventy percent is developed into heat. A cooling system protects an engine from damage by transferring heat to the atmosphere by using the radiator. A correct operating temperature is critical for the proper function of the engine which is controlled by the thermostat. Car manufacturers have found that a 195° thermostat is optimum for efficiency. Below this threshold the catalytic converter will not work properly which will produce increased emissions. In the beginning, water was used for cooling systems, as it's the most efficient fluid to absorb and dissipate heat. The disadvantage of using water is that it freezes at a higher temperature and, boils at a lower temperature than coolant besides causing rust. Eventual...

How To Replace Car Thermostat Helpful Information Like any mechanical device, over time, the thermostat can fail due to a weak spring or corrosion. If the thermostat is stuck closed, coolant cant flow which will result in engine overheating, if the thermostat is stuck in the open position, the engine will not reach operating temperatures in cold weather, passenger heater operations will also be weak. Coolant is toxic and can be fatal to animals and children so use caution when handling and be sure to recycle at a proper collection facility. Tools and Supplies Needed Screwdriver set Pliers Drain pan Socket set Gasket scraper or sand paper Coolant New thermostat and gasket Shop towel Best Practices Replace radiator hoses and clamps Flush cooling system When the system is hot it holds pressure, use caution. Easy step by step guide on how to replace an automobile engine cooling system thermostat, this information will vary per application but follows the sa...
