Coolant Levels Dropping Consistantly with NO STAIN ON DRIVEWAY

405

Asked by Dec 16, 2008 at 10:01 AM about the 1985 BMW 3 Series

Question type: Maintenance & Repair

Any trip I take over 20 miles my coolant light kicks on.  The level is going down, but not onto the ground as far as I can see.  There is NO water in my oil.  Any ideas on what may be wrong?  I thought i would have an answer if I saw white in the oil, but I don't.

Take it to a mechanic to have the coolant system pressure tested for leaks... Many cases it's about the only way to find it.

could be burning it... might have a bad head gasket

OK. I did some digging and think I have it figured out. 1) Noticed a slow leak at the new water pump I put in a few weeks...need to reinstall cause I'm an idiot. 2) 2 fan blades are broken off and missing...no idea how this happened. 3) Newspaper test...my fan clutch is shot. I think my fluid is short for two reasons. One is the leak. Two, it is running too hot and running back into the fill tank and blowing off. Any ideas on what happened to my fan blades? I see no interference with close-by parts...they're just gone

Ahh your culpriate is broken motor and transmission mounts they caused the motor to go side ways under torque and pushed your fan blades up agiants the shround shattering them. This in turn causes over heating and destroys your fan clutch. hope this helps

Your head is cracked. Same thing happened to my '88 325ix, no coolant in oil until about a month later I started noticing coolant in the oil. The head was cracked above the exhaust port so most of teh coolant was going out into the exhaust. Do a pressure check on the coolant system and take the valve cover off when doing it. I did that to mine and I saw the coolant leaking out of a crack about 2 inches long.

The coolant check light comes on every 400 miles .in my BMW 1999 323is...I put about a 1/2 cup of coolant in until about another 400 miles when coolant check light comes again...what do you think problem is?
