No heat.....
This is the first time, when I have problem with heater core. One hose is hot, the other is not. Coolant level is OK. How to flush it correctly? Can I use compressed air?

I would reverse flow flush it out carefully with a garden hose. I had this problem in Alaska a few years ago and did some good with the rv water system pump. I was never able to completely clean it out though. You must be careful because the garden hose can produce more pressure than the core is designed for.
I think you will see quite a bit of debris flow out of the unit. Always use distilled water in the radiator, I believe this keeps clogging to a minimum.

I have new thermostat. But coolant streem of heating core goes not throught the thermostat. Radiator is cold, it is hot inside, and when I put the blower to hight on "vent" regime temp. gauge drops. ECT read 75-80 dgr C, not the usual 90-95.
