blowing cold air

[winogak]

i have my ram 1500 2013 heater core replaced 3 years ago and now im getting cold air seems like just a little warner in the passenger side than driver some people say it could be bend door actuator but when i set temperature to cold it way more blowing cold air

i think my core is clogged and if its the case after 3 years my coolant might be comtaminated?

could it be something else than bend door?

i just changed my thermostat and added coolant in rad and in tank

thanks

Can the heater core be flushed?

Did you just get cold air after you changed the thermostat? if so ., you may still have a air block.
If it was real low, you could also get air in the system.
you can try flush it , flush both ways, I have seen a water gun with a low pressure air line hooked into the water stream, some times works, other times not so much from what I read.

Did you replace the thermostat due the problem existing before replacement and problem continues or did problem start only after replacement? As asked above, this is important to know.

First thing I would do is plop thermostat in boiling water and see if it opens up just to check if it is a bad thermostat. Not sure why you replaced thermostat thinking core was plugged.

Wait wait wait. You went with a *hotter* thermostat? Why???

i had the coolest one 190 f now im like 205 wich is the middle in the gauge its is just better for the engine running a little warner better oil flow in engine etc even with their hemi lifter problems i see zero reason running cooler
