Not enough heat in the winter

[4rcFed]

It has been in the low 20's all week, and it just seems that the HVAC doesn't blow really hot air now, even after it is fully warmed up. I end up keeping the blower on high my whole ride to and from work.

Anyone ever try one of these from Geno's garage?

Have you tried the utilizing the high idle feature with the exhaust brake engaged???? How long is the truck idling??? Any chance you might have an air pocket in the system since your warranty work was performed??? How many miles do you travel one way to work???

[4rcFed]

Yep, I do use the high idle feature, with the exhaust brake enganged.

I idle the truck before I leave the house, and before I leave work's parking lot. Not sure on the time, but I wait until the temp needle starts moving.

Air pocket would be possible, but I don't think they had to do any work in the coolant system.

It takes me about 30 minutes to get to work. I'd have to check the mileage.

What rpm's are you setting high idle at??? If your turbo was replaced.......there was a loss of coolant as the 6.7L VGT turbos are water cooled.

[4rcFed]

I think my high idle is set at 1000-1100 rpm.

I forgot about the liquid cooled deal. There might be an air pocket in there. I need to figure out how to burp this system, to at least try something.

I *think* there's a bleed screw around the EGR cooler (highest part of cooling system) and you might also want to try using the accel feature and bump it up to 1,300 or 1,500.....

[4rcFed]

Sometimes I bump it up to about 1300, but I usually just keep it around 1100.

I'll check into the bleeder screw this weekend most likely.

Thanks Southern Bro!

Just a few things to think about.....maybe some others will chime in as well. Is block heater usage a feasible option for ya????

[4rcFed]

I never thought about it when I was in KY. But I have thought more about it this week. I never checked for the cord, but I believe that these didn't come with one. So I was thinking about ordering one, just in case anyways.

I thought they came stock in 08 but I may be wrong. Mine was on the lower right side (passenger) of the radiator. it was tucked in behind the radiator so I fished it out through the bumper for easy access. I will tuck it back in in the spring.

During use the heat gauge just moves a hair. But it still takes a few miles to heat up the truck.

Two 10" pieces of cardboard in front the radiator has done the trick for me. We've been below freezing and sub-freezing for a few weeks and engine temps climbed fairly quickly using this technique. I kept an 8" gap in the middle of the radiator and two cardboards chunks on the outer edges (zip tied to the hose above the rad)..

Get the Mopar one, it has way better flaps that you can open depending on how cold it is so you can let more or less air in if needed. I love mine, warms it up nice and fast and even when its stupid cold......This picture is fully open by the way
Mopar part number for the Cold Weather Kit 82208646
Got mine at the local dodge dealer

This is not my picture by the way but I do have the exact same one
