Does Anybody Else Do This?
Whenever I return home and put the car into the garage, I open the hood to let the heat out more quickly to keep all the plastic and rubber bits and the electronics from soaking in that heat for hours. The hood then stays open until the next time the car is driven. Been doing that for years, and everything in the engine bay still feels supple, even after 21 years. Just wondering if anyone else does this, or if it's something I ought to tell my therapist about??

I do it all the time and even have my wife doing it although her motives are to save money.. In the winter time the heat from the engines will raise the temp in the garage a good five degrees, and our garage is separate from the house and I keep it heated in the winter. I mostly do it for the same reasons you do though.

No and this is what it looks like. I did replace the manifold vac line to the switch over valve. A friend helping me with a valve adjustment snapped it off, oh well, easy to put a new one on.

Hmmm. I never thought of this but it does not sound like a bad idea. I suppose the heat under the hood increases when you stop because the fan is not running and you don't have the ventilation from driving down the road. I'll bet it spikes up when you turn off the car and then slowly drops down.
As far as heating up the garage, I would argue that the heat is in the garage anyway and the same amount of energy will transfer into the garage whether you open the hood or not. It will just transfer faster with the hood open.

I only do it if I know I'm going to be working on it later. It takes forever to cool down to a reasonable level where I won't get burned.

I only do it when it's cool enough to actually get some results. It's been 116/110 degrees here and we have my car and my moms in the garage, when the garage closes and the engine heat from both of those cars heats up the garage... ah man that's what I would imagine hell to be like lol It gets so hot in there you can't breathe.
I want to leave my car out in winter though, so it cools quicker.

Drivers in India do it commonly till today, they call it letting the heat out, always laughed at this concept. Don't know how much heat is dissipated but if your rubbers have outlasted others, you may have a point there.

Yes, and sometimes I do this in the winter in the morning if I am the first one up and I want to warm up the kitchen. But the difference is that when you open up the door to the oven, it cools down the oven and triggers the thermostat to fire the oven again. But when you have turned off your car, no more source of heat. You are not changing the amount of kinetic energy at the source, the engine block, just distributing it at a different rate becuase you remove a layer of insulation, the hood.

How many miles on that SD? Looks like a new engine.

fast/slow
I thought about opening the hood after parking, but then I decided that allowing the heat to escape quickly wouldn't be as good as allowing heat to dissipate slowly. Less thermal shock.
