I do not understand a few things:
If the Thermostat is 185°F to 190°F, does that mean that the water in the hoses is the same temperature ?
If the water inside of the hoses does reach that temperature, where the hell does that heat disappear to after passing through 5 foot of hose ?
I can tell everyone, that the heat in my Ram, even when new, never came anywhere near that temperature, even with the Recirculation door closed.
Take a ride in a Ford truck that is 5 or more years old & you will not want to keep the heat turned up to full heat.
The same when it comes to the hottest part of the summer, our Rams do not really cool off the inside of the cab when the outside temperature is over 100 - 112°F plus
The temperature inside the hose better be close to the thermostat value, I'd guess within about 5° or 10° depending on the outside ambient but don't forget, we're measuring the temperature of the outside of the hose.
IIRC, I saw about 175°F where the hose goes through the firewall and into the heater core.
So maybe, the thermostat value less 15°?
I've read countless reports that describe poorly performing HVAC on Ram trucks, mine is not one of those.
It takes no effort to make it meat locker cold in the summer or blazing hot in the winter.
I have no idea why my Ram's HVAC is excellent and others are not.
