retarded coolant everywhere

[a_thomasmr23]

So I just finished up a head replacement (timing belt) Everything is together but i have coolant dripping from somewhere i can't find. It in the very front of the block and the back. There is some pooled on that flat area on the passenger side where the block sticks out a little more but it doesn't grow, move or drip from there.

Also, I only got about 7L of coolant in there started running it and I get no heat but the coolant in the reservoir does not go down either. Engine temp will change when reved and the heat will work then.

I'm at a lost here what should I be looking at?

As to the leak, a pressure test of the cooling system should quickly reveal the source. As to the lack of heat in the cabin, that's probably caused by air in the cooling system. The procedure I use to bleed the cooling system on a BMW is:

1) Using ramps or a jack get the front of the car 1' or more higher than
the rear. That will make the radiator and bleed screw the highest point
on the engine and facilitate removal of air.

2) With the bleed screw open, add coolant until no more air comes out of
the bleed.

3) Leave the filler cap off, or at least loose, and set the heat for max
temp and fan speed. Leaving the cap loose will prevent air that's still
in the system from causing a "coolant fountain" once the engine heats
up. Start the engine and allow it to warm up to operating temp. As it
warms up occasionally crack the bleed screw to release any air and top
up the coolant as necessary.

4) Once the engine is at temp bring it up to 2000-2500 for a few seconds
several times. Then crack the bleed until no more air is released. At
this point the heater should be throwing lots of hot air, which
indicates that the heater core is filled with coolant. You may have to
repeat this a few times to get all the air out.

5) Drive the car a bit, allow it to cool back down, and recheck the
bleed for air. Over the next few days you may get very small amounts (a
few bubbles) of air out of the bleed screw.

pressure test good call didn't think of that

thanks!
