New Heater core but still no heat!!!!

[mikeinmaine]

Hi ALL, So my daughters car(1993 318is coupe)had no heat when maine winter hit and i have been trying to figure it out since. New water pump and new heater core and thermostat and still don't have heat. I took the water(heater)valve out and put a T in its place to rule that out and i can feel some heat on one side of heater core(haven't put dash back together yet)but its not really enough to blow any heat once fan is on. I have bleed it a TON of times and jacked front up to help too. The only way i could get it to take in more coolant is to warm it up and shut it off then it sucks the coolant out of the expansion tank but last couple of times ive done this it hasn't taking any more coolant into the engine.
PLEASE someone smarter than me help me out as i am stumped and my daughter who is a single mom really needs heat

The factory method is to use the air bleed with the temp controls full hot and the heater on as you fill.

You should be filling until the bleed leaks coolant..

Try doing this on a slight uphill incline to force the 'air pocket' to the highest point of the motor.

Tried that without car running but would not draw coolant in. At temp i have loosened bleed screw till steam has escaped and coolant starts to come out. But as far as getting coolant into engine i had to warm to temp then when shut off and as it cools it draws the coolant in but is not drawing anymore in and still no heat. Have tried bleeding with front end slightly inclined and now have it jacked up about 1' on front end,still no heat and not taking any more coolant in.

Also with the heater valve removed and a T in its place it shouldnt matter if heater controls are on high,they are anyway but imo it shouldnt matter as there is no valve to stop coolant.

[Turbohugh]

Are you sure the T is open to allow flow to the heater core?

[mikeinmaine]

Turbohugh, Yes the "t" is just a 3/4" open t with no shutoffs or anything so wide open. Thanks for helping though bud

Still cannot figure it out and the closest BMW dealer is over 3 hrs away

I am having the same issue but when i as a say"burb" the system i leave the fill cap on, the heat on high and remove the bleed screw completely, i also bring the RPMs up at the throttle body while doing this. I usually get heat back for a few. then it goes out again. I have to burb the system one to two times a week. it also goes thew a bottle of coolent a week. head gasket is good the cooling system is all new including water pump. the only components that are not new is the exspantion tank and heater core. but sence the heat some times works I figure the core is good.

sorry for hijacking your thred I am at a lose on this too.
