What is the need for coolant in the cooling system?
The primary purpose of coolant is transferring heat and preventing engine damage caused by freezing or boiling. Heat can only be effectively transferred with a liquid in the system, so it’s crucial to keep your coolant from freezing or evaporating.
What kind of coolant do you put in a radiator?
Using pre-diluted coolant, as opposed to concentrated or full-strength, is an easy, no-fuss way to ensure your radiator has the proper 50/50 mixture of coolant and water. Run the engine until the cooling system stops bubbling and the coolant level starts to rise, then put the radiator cap back on the system.
When do I need to top up my coolant?
Should you need to top up, make sure you use the correct coolant and mix refer to manufacturers specification. Only top up when the engine is cold. Again if you are unsure check with the handbook Check your vehicle handbook for the location of the coolant filler cap – the advice given may vary from car to car.
What do you need to know about engine coolant?
What Is Engine Coolant? Engine coolant, also known as antifreeze, is mixed with water to keep the radiator from freezing in extreme cold and overheating in extreme heat. There are many different types of coolant, so it’s important to know what variety is right for your car or truck. Different vehicles require different coolants.
How often should I change engine coolant on a Mercedes?
The interval is every 30,000 miles on some Mercedes-Benz models with some engines, but on others it’s 120,000 miles or 12 years. On still other Mercedes, it’s 150,000 miles or 15 years.
Where does the coolant go when the radiator is cold?
So the coolant in reservoir can be sucked back into the radiator when it is cold even if the level is not all the way at top. (Most cars only have one hose at the bottom of the reservoir; seeing the hose at top made me thinking that was the only one without examining the bottom carefully.)
What should the coolant level be in a Mercedes Benz?
Use MB coolant or Zerex G05 (usually carried @ NAPA). Premix to 50/50. A gallon of coolant and the rest water is probably fine. Car should not be running but afterward, run car with heater running and always check level later. Mix must be 50/50 according to MB, or else car will run higher temperature than intended.
What should I do if my coolant level is low?
If the coolant level is low, water and MB anticorrosion/antifreeze should be used to bring it up to the proper level (have cooling system checked for signs of leakage). The water in the cooling system must meet minimum requirements, which are usually satisfied by normal drinking water.
What kind of coolant do you use on a MB?
MB does not have separate pressurized cap for the radiator, so the expansion tank is really part of the system. BTW, every one seems to say that other than MB coolant, you should use Zerex G-05. But last time I took my cad to MB dealer and they filled it with “green” coolant!
