I commute 60 miles each way for work, and recently puchased a used 2014 Summit GC as my daily driver. Prior vehicles were Ford Fusion and Audi S4.
When I get home in the evenings I've noticed the GC heats up the garage like a MOTHER! I come home, park, close the garage, change/get cleaned up, then head out to the garage beer fridge and it's like 15-20 degrees warmer out there.
Never had this problem with my other vehicles, or even my wife's black 2015 GMC Yukon.
I've recently started leaving the garage door cracked open for an hour after I get home. Next step might be installing space shuttle tiles all over my parking spot!
My wife's 3.6 does the same thing. I have a thermometer in the garage. When she comes home from work in the summer time, it usually gets up to around 100 to 105 in the garage.
Mine is Granite Crystal Mettalic. My wife's Yukon is Black and doesn't have the same effect. My other two cars were also black and still didn't heat the garage up that much. It's crazy. I'm wondering if it's because it's full time 4WD...
4WD won't make it hotter but the 3.6 does run hotter than other vehicles I've owned. My theory is that the GC has a ton of insulation in it and it holds heat better than other vehicles. I noticed this in sort of the opposite way- we had a few 90+ degree days this week and when I got in to drive somewhere after it sat for a while and the interior was nowhere near as hot as my past vehicles in the summer though to be fair my most recent previous vehicle was a Wrangler which is about as well insulated as a soda can.
Was out with the wife today and got home around 6:30. I went out to check something (related to the oil change I had) around 9:15 and the engine was still putting off a pretty good amount of heat. I felt my catch can and it was still pretty hot. My garage was probably around 75 today.
I've noticed that my 17 GC gets super hot as well. The temp needle inside isn't even half way but still the GC throws off a lot of heat. Noticing it a lot more now that summer is here and it's hot in Houston.
Same here. Last week I pulled into the garage to change the oil after a trip across town. It took 4 hours just to reach a point where I could touch the filter without burning myself, and the garage went up 20 degrees.
Then again, I have a black 5.7l in west Texas [emoji15]
Cast iron block will put out a lot of residual heat when turned off. Though it's pale in comparison to the heat that my previous 2003 Ford SVT Mustang Cobra and 2010 BMW M3 Coupe would throw off. Yet those had smaller aluminum V8's by at least 1 liter. Go figure.
Here's a thermal image I took in my previous garage about 30 minutes after arriving home on a day where the outside temperature was around 30 degrees F.
I took the pic to check the efficiency of the insulating job I did on the wall that leads into the house, so it wasn't directly meant to photograph the Jeep.
As you can see, though, there's still a lot of heat coming from the engine area even on that cold day.
The only other real source of heat was the overhead light that was turned on at the time.
