water issues

hello all,
first of all had my bmw for about 9000 miles with no probs but recently (the last week)put water in it twice because the heater was cold even on hot thought it was an air lock but not sure anymore.
there is no water in the oil, neither is there any signs of a visable leak.
any ideas??

well if you are having to put water in it that often there has to be a leak some where.
you should start by looking at the evaporator or at the heater valve or expansion tank

Definitely sounds like there is still air in the system, I would re-bleed it!




It really helps to have a friend lend a hand by sitting in the car revving the engine and keeping an eye on the temp gauge. Start off by removing the coolant reservoir cap and the plastic bleeder screw right next to it. Fill the coolant reservoir with a 50/50 mix of coolant and distilled water. Have your friend start the car, turn on the heater to full hot on the vent position and rev the engine to about 2500 RPM, if the temp gauge goes past the 12 o'clock position, shut the engine off, let it cool down and start over again. Watch the coolant reservoir, as the engine warms up the coolant level should drop, refill as the coolant is sucked out of the reservoir. Watch the bleeder screw hole also, when coolant with no air bubbles begins to overflow then you're almost done. It's a good idea to have some paper towels handy to mop up any overflow. Screw the bleeder screw back in (be careful to not break the plastic screw) and continue to rev the motor, you should see a continuous stream of coolant spraying in to the reservoir from the small hole at the top. Continue letting that spray in to the reservoir while your friend revs the engine for a couple of minutes, until the gauge hits the 12 o'clock mark, to ensure any remaining air is gone. If the heater is blowing hot air when you're revving the engine AND when the engine is at idle then your cooling system is properly bled. If your vents are blowing cool air at idle then you still have air in the system, try revving the engine more and/or squeeze the radiator hoses to help dislodge any trapped air. Once your system is fully bled, top off the reservoir and replace the cap. Check the coolant level in a day or two and top off as needed.
