Getting Rid of Exhaust Fumes in Attached Garage

Picked up a '24 dually on our last trip to Florida and now that we're home, I wanna get the new truck in our 2 car garage. When I pull the truck in nose-first, it gets pretty tight between the truck hips and my wife's car ...too tight to be honest. Backing the truck in gives way more room and is a great solution - except the exhaust pipe is now right next to the door going into the house. Its not so bad when I back the truck in when the engine is fully warmed up. It's the morning cold starts that are too much. Right now widening the garage door so I can pull in nose first is out of the question. Have any of you installed some kind of fan to help with the fumes? My other thought is a piece of exhaust tubing that automotive shops use. Would be a piece of cake for me route tubing outside an exterior wall in the garage.

Depending on your layout and carpentry skills, a vent fan with outside auto louvers near the exhaust outlet might do the trick. Open the garage door several inches, hit the fan switch and you would be good to go. You could even put a bath fan type timer on the fan so it runs a bit after you leave.

I probably should get a photo or two, but what you mentioned is similar to what I was thinking. I'd use 6" round HVAC metal duct that would run just above floor level from the truck exhaust pipe area and exhaust out the back garage wall with a damper in it. Total run length would be no more than 10 feet. I'd use a round inline fan on a bath timer to move air through the duct. Distance from the truck exhaust pipe to the 6" metal duct intake would be 2 feet or less. I'm thinking this would remove a bulk of the exhaust (which would be heavier than air I believe).

How long are you idling in the garage for? It should be no more than fire up, let oil pressure build, and pull out.
Good question. In the past I've always idled a bit for warmup before backing out. We're in MN and it gets pretty cold some mornings. Now that I'd be backing in, I'd basically do what you are saying. Start, wait a few seconds and then start pulling out. Pulling out though is a little slow....the dually hips get close to things as they move past the garage door area. Minimal exhaust problem when starting and pulling out with a warm engine. When cold however, that first start of the morning is pretty strong exhaust....
 
I also back in my garage so the exhaust is near the door into the house - but there is almost nothing coming out of these tail pipes with these modern emissions systems - I hardly notice any smell at all in the garage when I start it up and pull out (and smell nothing at all inside the house.

You want to idle these trucks as little as possible, so if it’s cold and you want heat faster plug it in.

When we lived in MN, it was in pre-DEF days. So starting a diesel in the garage in the winter left a lot of fumes. Wife complained about it quite a bit. So I insulated the attached garage and hung a natural gas heater in there. Always kept some minimal temp like 45. That way I could start the truck up and immediately get it out of the garage. Worked for us.

Another to-do for me. Bought the truck from a dealer in Atlanta, and it does not have the winter package. Gotta order one of heater cords and get it installed.

I lived in north Iowa until fall of 2018, on cold sub zero nights I put the block heater on a time to come on between 2-4 hours before I had to drive the truck, thus at -25 below I would set the timer to come on 4 hours before I needed the truck that way I could just open the garage door an back out and if I felt it needed more warm up time I did so outside the garage, its much cheaper then running a gas heater and insulated the garage...
 
We have a 2 car garage with a standard 16' garage door. The only way my trucks have ever fit is because one of the bay's is 8 feet deeper than the other bay (where my wife's car goes). Since the truck has to be on the deeper (right) side, I can't switch sides with her. In my case, a wider garage door would allow me to pull the truck in nose first - but this 16' door makes it just too tight between my truck and the wife's car due to the dually hips. As much as this issue of the truck barely fitting in bothers me, I try not to whine much as I know not everyone has a garage that they can even pull into.

Probably, although those block heaters eat some power. Over a lot of years of up north winters, it would probably add up. I did all the work to insulate the garage and install the heater myself, so it wasn't too expensive. And then I had a place to work on my bikes or other projects in the winter. A total win-win for me. I lived up there for 35 years and there is not a lot to do in the winter (once pheasant season ended anyway). So being able to work out there helped pass those painfully long winters.

Which should be pretty dang quick with synthetic.

I back my daily into the garage (makes it easier to get in/out of), and do exactly as quoted. Start it up, wait just a second, then pull out and shut the door behind as I let the car warm up further.
