Reply to "Erica needs to get hosed....."

OK, Erica has been on "time out" for being such a Beyonce..... I need a sanity check here cuz I'm going a tad crazy....can't afford to lose more hair!

Whut I done so far....

Repaired Evap/Heater core is back in car, holding 28+ inches of vacuum for several days while I have been trying to get heater core to work.....

Today determined that core has no obstructions, valve is adjusted for full flow capacity (about a 3/8" passage), and my home brew heater line filter is not plugged up already.......

I need a sanity check here......

Heater core is connected as follows....(similar to other post two up the list)....

The open line on the core is connected directly to the back to the pump which should be "sucking" water from the core..... (Left hand tube)

Valved side of core goes back via RH tube and hits my filter and is then connected to the block outlet. This is the pressure side...

Water pump "pumps water" into the block, from radiator, which is heated, then is pumped out the block fitting and forward to the heater valve...into the core...and back out...returning to the water pump. It should be as simple as that.

Pressure side of core is valved connection, suction side is the open connection.

But for me....no love. The two metal hoses up at where they come out of the tunnel are barely warm.....engine is warm enuf to turn both fans on......

I had flushed these lines several times, although had lots of crap in them......seemed clean.

SO, is this something unique to our cars, that the core needs to be bled????? Air bubble issues?????

I would think that with a suction on one side, and pressure on the other, that water would displace air and these lines should be cooking in no time......

What stupid simple thing am I missing?????

Cheers!
