thanks guys, got it off, just need to test it now, do you just hook it up to test it or can a radiator shop test it a better way?

I have this problem that when my elky arrived in Finland, she had heaterhose connect to each other, so that heater core was cut off. Basically it runs straight from cooler to engine(or vice versa) and there are two open hose that were cut off running from heater housing. And now I am wondering, could I just reconnect them and expect hot water running through the core? The fan is working so there would be heat from the vents. But the question really is that is there anyway to make sure that the core is solid and won't leak, before I'll do this reconnecting? Thanks for advice, didn't want to start a new thread.

Lemmy,
Do you have a small hand vacuum pump? If so seal one of the tubes completely and rig the pump to the other one and pump it down and see if it holds.
You could also rig some way to pressurize it (NO MORE THAN 15PSI) and see if it holds.
Odds are that with it cut out of the system it is going to leak.
