What is the direction of flow at heater core?

*note* - this is NOT the case for EA81's. Only EA82's.

I think to clarify it should be said that the outermost hose, the one that gos straight under the manifold to water pump is the inlet into heater. The one closest to the center of the car, coming from the intake body is the inlet. They can be reversed as GD said, but then the two hoses would cross over eachother, and the water is still going in the same direction through the hoses, just backwards through the heater. This is good to do when you run a cleaner through before your flush. Switch the hoses, run the cleaner and do your flush. Then switch them back(or not) and refill system.
The one on the left/bottom is the inlet.
I've also flushed just the heater core with a garden hose cut and clamped on to the outlet.
As a side note, poor coolant circulation can cause the same effect on the heater function. How sure are you that you've got good pump circulation? If you've run just water for a while, and you've got an aftermarket waterpump, the impeller may have rusted away. You would likely be overheating or running hot sometimes as well. If you've got good antifreeze with no rust in it this is probably not the case. Just thought I'd pose the question.

and not to hijack the thread... GD, what is wrong with doing it on an ea81? is there something like a 1-way valve in there? bad for the flow control flapper thing?
