Let Heat Out From Under the Hood

Friends that have been in my garage have noticed that my hoods are usually open. It’s not because we drive clunkers, altough I suppose that’s a relative term, but no it’s to free the heat!

Let the heat out!

Did you know that your car’s engine electronics and wiring will last much longer if you open the hood when parked in the garage? Modern cars have their more than their fair share of plastics and electronics in the engine compartment, and excess heat is not good for their longevity. The difference between having to replace sensors and control modules after a few years on a new car, and having them last a decade of more, could be due to avoiding repeated heat spikes.

When you’re driving around the heat in your engine compartment is carried away, and when parked outside the heat also gets carried away by air currents. However, in your garage, especially in the summer, there is little air circulation and your engine compartment becomes a virtual oven. With a closed hood components will be heated to very high levels, and they will remain hot for a much longer than usual time.

Now I know that some people get a new car every few years or lease their vehicles, so they may be thinking that this doesn’t apply to them. We’ll, while they may not have to pay for the repairs they could consider the next owner. That would be good carma, pun intended.

Now go open your hood, and save money. Does it need to be said that you should close it securely before driving away the next day?
