Changed thermostat, too much heat from air vents?

[wikdslo]

I've not had the truck very long, and I haven't driven it much since I have. Recently I did the thermostat which was failed open, and reused the coolant that was in there. Didn't need to add much in to the system to top it up and the level looks good.

However, the heat coming out of the air vents is pretty damn hot! I always thought these diesels didn't make good heat, especially in winter. Is this indicating some problem or am I just over worried?

I have an insight cts monitor and the ECT looks good and doesn't fluctuate much at all.

Thanks!

You are paranoid, there is a thermostat of sorts in your truck. All the way to red is hot, middle is warm, and all the way to blue is cold.

AC is better in the GM's IMHO

but when your normal ECT coolant temps are 180-210 ish

that is just as hot as a gasser ,, We just take a little longer to get there with our oil burners

Great heat, no doubt about it.

The phenomenon is called heat/cold soak. If you have the auto system, it will blow hot until the sensor is at the selected temperature, then start to regulate. If you are in the front seat, you will get very warm, while the rest of the cabin warms up, including the metal under the dash. That is why you can manually adjust the fan or the temperature.

I'll relate this to an escalator... you are part way up and it stops... your choices are:
1) Do you wait for it to start again to take you to the correct level, fearing you will be trapped on the escalator, or
2) Do you take action to finish the walk with human power?

These days...........most people wait for the escalator to start up again........

I'd say if the escalator is that big of a piece of cra.p that it stopped

I just want the door to open so I can find the stairs

However you have lost Me in the comparison ,, and I am OK with that !

Escalators with doors? I'm so confused

But thx for the input folks. The PO told me that the heat was not so good in the truck. Maybe that was on account of the stuck open thermostat

My only other diesel experience was an 81 VW rabbit which, bless her tiny motor, was not the creme de la creme of heat boxes come winter.

Good to know that everything is normal then. Was afraid of an air pocket in my heatercore or something, despite the fact that I can feel the coolant coming out of the heater core return hose and all.

And to twoicebergs, thx for the explanation. That makes a lot of sense on how the system works. One of the vents was pointed down to the center console where my phone was and it was damn hot when I picked it up!

Cheers.
