My exhaust brake comes on as well. It creates back pressure heating up the engine. It remains on while parked.

My Jeep Liberty CRD has a Viscous pump with an electric clutch. When the parameters are met, it creates warm water and pumps directly to the heater core. Works great over 1000 RPM. Once it gets to temp, then it pumps engine coolant to the heater core.
From Green Diesel about the EcoD
Quote:
For those that are not aware, the Ram ecodiesel is equipped with 3 PTC heaters in the HVAC system designed to provide quick cabin heat after starting the engine. A PTC is essentially a coil heating element in the air system ducts, similar to a hair dryer. All three PTC can pump out about 1000W.

The stock tune will idle at 1400 rpm is the HVAC requests the PCM to turn on the electrical heating elements (PTCs). For this to happen, it generally needs to be 50 F or colder outside and the coolant not warmed up. If you have the single-zone HVAC system, the temperature selector needs to be at maximum heat setting and the blower fan on at any level above zero. If you have the dual-zone HVAC it should only need the heat setting above the middle point and the blower on.

Granted, the 1000W PTC output is a bit low for the size of the cabin, this will help provide quicker heat than waiting for the coolant temps to rise.

Hey. LostJeeps seems to be down. I am also on the Ram1500Diesel forum. One of the first to join (#60). Now, they are getting close to 7500 people who joined. Just got my EcoD after GDE had a tune finalized.

If you really want a warm truck and cab; installing an ESPAR Heater is the only way to go. Especially if you live in the land of the frozen tundra (north of the lower 48 states).
See this link from "Turbo Diesel Register. Com". A member added this to his truck and posted this write up.
