Is Bleeding cooling system necessary?

You need to bleed the air out of the cooling system in your car. Air pockets — or hot spots — are dangerous. Besides causing little or no heat to come out from the heater, it may cause: Engine overheating.

How do you bleed a Mercedes cooling system?

  5. When the car is warm (about 81 C) get in to the car And turn on the heater (red line) on max.

What is reverse flow cooling system?

One of those developments was reverse-flow cooling—the practice of circulating coolant from an engine’s cylinder heads into its block, rather than the other way around, to reduce the risk of detonation.

How does reverse flow cooling work?

Coolant flows from the lower radiator hose into the water pump at the thermostat through the heads on the way to the block. The reverse flow pump acts as a vacuum pump in drawing the water out of the block. It then passes the thermostat and returns it to the radiator via the upper hose.

Where is the thermostat located in a reverse flow cooling system?

The thermostat is located between the engine and the radiator. This little temperature-sensitive spring valve stays closed during engine warm-up. When the thermostat is closed, it prevents coolant from leaving the engine and circulating through the radiator until the correct running temperature is reached.

Why do I need to bleed my coolant system?

Oftentimes whenever you change a part on the coolant system such as a radiator hose, water pump, or thermostat you will need to bleed the system of whatever air you introduced. Air can also get into the system through a faulty water pump gasket or through a faulty radiator cap.

Can a bleed screw be removed from a cooling system?

Warning! Don’t remove a bleed screw while bleeding the cooling system or you may seriously burn yourself with hot coolant. Once the engine has reached operating temperature, turn the coolant bleed screw one to two turns counterclockwise using a wrench of the correct size.

What’s the difference between manual and air bleed?

The manual method is the old style variant of bleeding the coolant system. Some cars have an air bleed valve to get the air out from the system, and some cars don’t have this air bleed valve which makes it a lot more difficult. However, the method for both of them is the same.

How to Bleed your car’s cooling system-axleaddict?

Fill the radiator with a 1-1 ratio mixture of distilled water and antifreeze up to the bottom of the radiator neck. Mix only distilled water with the antifreeze. Add coolant to the reservoir container to bring the level up to the “Cold” mark as well. Leave the radiator cap off and start the engine.
