Tank 250cc motorcycle bleeder for radiator

Try using a vacuum bleeder to draw the fluid through the system.

There's trapped air in the cooling system.

• You need to remove the bleeder screw on top of the radiator when adding water to the expansion tank.
• With the engine running, pour water into the expansion tank till you see air go out through the bleeder screw's hole.
• Just keep adding water until no more air bubbles come out then just put the screw back in place.
• Then fill the expansion tank to it's normal level/line.

Just did my 95 525i. Most importantly, make sure all of the air is out, then tighten the bleeder. Let it run. If the reservoir is over flowing than it's over full. Keep an eye on the temp. gauge for bout 15 min. If it goes over normal operating temp. you still have air in the radiator and need too bleed more.

bad thermostat and coolant maybe low. when a engine gets to hot at certain boiling point it evaporates

SATURN USED A PRESSURE COOLANT SURGE TANK AND A INLET SIDE THERMOSTAT.THEY DONT HAVE BLEEDER SCREWS.YOU NEED LET CAR SET A LITTLE AT A TIME CRANK ENGINE FOR FEW MINUTES TURN OFF ENGINE.CHECK COOLANT LEVEL WHEN ENGINE SET LONG ENOUGH NOT TO SCALD YOU REMOVE PRESSURE CAP.ADD COOLANT TO SURGE TANK UNTIL LEVEL STAYS AT HOT FULL.WHEN COOLANT LEVEL QUIT DROPPING YOU HAVE THE RIGHT AMOUNT COOLANT.YOUR PRESSURE CAP COULD CAUSE OVER HEATING AND THE THERMOSTAT COULD BE BAD ALSO.

There is no bleeder screw near the thermostat. There is a bleeder screw on the expansion tank... It's by the radiator, it's about a size of a dime, and you use a large flathead screw driver.. Becareful it is plastic, so don't force off or on. In some rare e46, there might also be a bleeder screw on the upper radiator hose.

not too difficult just make sure you bleed the system properly. two bleeder screws. one near the thermostat housing and one at the expansion tank(where you would fill the coolant) i would recommend replacing both bleeder screw and don't lose the four rubber pieces that are used to mount the radiator properly(can reuse the old ones)

the thermostat (on bmw replacement parts) have an arrow that has to be installed facing upward.if this was done correctly,to bleed the system usually there is a bleeder screw on or near the expansion tank(where you fill the coolant) and possibly on the thermostat housing. i would recommend opening both bleeders and keep filling the system with coolant closing the lower bleeder first and then allow the rest of the air purge from the other bleeder screw.make sure the coolant stays full and be patient you can't wait TOO long.

There should be 2 bleeder screws in the system, one on the expansion tank, and one on a thermostat housing. Open both screws all the way. Turn the key to the On postion (but dont start the car). Then turn the heater to max heat, but have the fan set at the lowest setting. Fill the expansion tank til coolant comes out of both bleeder screws with no bubbles. After that close the screws (be very careful not to over tighten them!!). Then completly fill the expansion tank. (dont mind the full mark, if theres air in the system, it will drop the level in the expansion tank) And thats it. Drive the car around then check the level.

there can be a yellow light in the cluster that looks like a small radiator or box with waves inside of it to indicate water. This light means that the coolant level sensor has detected a low coolant level. Typically the expansion tanks inside of these cars will crack from heat and age. A simple diagnosis is to check your coolant level and top it off. Do not forget to bleed it by unscrewing the bleeder screw found on the upper radiator hose while filling up the reservoir found on the right hand side of the radiator. once the coolant has been filled, tighten the bleeder screw back down but be careful not to over tighten. and finally screw on the expansion tank cap. run the vehicle to operating temperature and use a flashlight to inspect the engine bay for leaks. If there is a leak, it will need to be repaired. possible leaks are a cracked expansion tank, leaking radiator hoses, or a leaking water pump or thermostat.
