how long for heat

my haney acert takes about 1 hr to blow heat. but thats with a 4 row rad and 180 stats on a cold morning.

 

It shouldn't take that long, the coolant circulates to the heater core whether the thermostat is open or not, an hour to warm up isn't good.


Also, for any diesel in cold weather, speed up the idle on it, letting it idle at low speed will take forever to warm up and if you idle for long periods, cause condensation in the engine and exhaust.

 

I always do that but I leave it at low idle until I feel it's stable enough and steady enough to raise the idle...I dont want to cause engine damage...

 

it's normal for me on a 10deg day. last truck did the samething.

 

I don't see a choice on low or high idle when starting cold. if the engine is cold, it will idle high until warmed up. when engine is at operating temp, then you have a choice to idle high or low.

 

Not my 99 Detroit. She will idle at 700 cold or hot. No such thing as a 'cold fast idle', like my cars have.
I can kick it up to fast idle by engaging cruise at any time, which is usually set at about 975-1000 RPM
- just enough to calm the vibration down when you need to sleep with it running.


Maybe you have a newer rig with a different setup...

 

Are you around Tioga ND ???

 

No, the Idaho side of the Tetons, by Yellowstone.

 

You don't need a winter front when going down the road until temps hit atleast BELOW 0F. Anything above that and you are wasting fuel and doing potential damage.

 

Care to explain that theory? Warm engine will burn less fuel than running too cold and no damage unless the driver just really dummies up and overheats the engine by closing off too much air. Seems that everything about a truck requires a dash of common sense.
