Heater valve location
Hello
I have 2004 F250 with 6.0 powerstroke. It is -20 celcius degrees outside and it does not blow hot air, even when it runs like hour in idle. I googled heater valve location but i dont have it on top of passenger side cylinder head. My truck is not us model, door sticker says export model and it is cheapest model. 6.0 powestroke, auto trans, manual transfer box, crank windows, no central locking. It has cruise control and manual air condition.
Vaccuum pump in passenger side of engine bay works and creates vaccuum. Cooland hose which goes from front of engine to cabin looks original and there is no heater valve, it is also hot. But hose which comes from cabin which goes to driver side y split is cold.
I couldnt find heater valve easily and it is freezing cold outside so i gave up. Does anyone here know where it might be?

You've got the location of the heater valve correct. Not all trucks have them. You would have seen it in the line going to the heater core on top of the passenger-side of the engine.
Your cold return hose is important. It could mean 2 things:
1. You have a blockage somewhere in the heater core or hoses. Feel around see see if you can locate the point where it goes cold.
2. Your heater is working just fine and sucking all the heat out of the coolant. In this case your low temps would be due to low coolant temperature.
To determine actual coolant temp you would need a scanner. It should be around 190F once warmed up. The stock idiot gauge can be helpful hear, it generally hits middle right around 180-185 which should be plenty hot enough to give you heat.
6.0's create very little heat at idle, so sitting there for an hour in -20 it may not have fully warmed up. The stock gauge should at least tell you this if its getting to the middle.
