It’s hot almost everywhere in this country right now.

Air conditioners are straining. The words “heat dome” are in the news. Climate change is being discussed.

Piston Slap: Vapor Lock and the Hot R32?
Nick writes:I bought a used 2008 Volkswagen Golf R32 with 48,000 miles in January 2010 (5,000 only in the U.S., 3.2-liter NA V6). Every summer since then I’ve had issues as the weather warms up. Basically, it starts to act up when driving at around 85+ miles-per-hour or so, and it gets even worse if I’m stuck in any kind of stop-and-go traffic. The only sure fix is letting it sit and cool off for 30 minutes or longer.

Down Under You Can Cook Christmas Dinner In Your Car, And That's Not Good

Australian chef Matt Moran made a video to highlight the dangers of leaving children unattended in cars during the holidays — and for the rest of their summer — by cooking lamb in the car, according to Australian newspaper The Age.

The video was produced for Kidsafe Australia, a group that highlights the dangers of leaving children in hot cars. Moran calls the car his new “ unconventional oven.”

The lamb was actually overdone in the 90 minutes it baked in the sweltering heat near Bondi Beach.

Piston Slap: So Hot, Yet So Cold!

Nick writes:

Hello Sajeev,

(I really wanted to put the “n” in there.)

I have a ’97 Prelude that will sometimes cycle on and off its air conditioning when it’s unbearable hot outside (June-September here in Phoenix). Air will come out nice and cold, then it will get real warm suddenly for about 30 seconds before getting cold again. It only happens when it’s extremely hot outside and I’ve been driving for awhile. It works fine the majority of the time. What do you think?

Baby Dies After Being Left Alone Inside Hot Car

A 10-month-old baby is dead after being left alone Thursday inside a hot car in Austin, Texas, KTLA reported. Police haven’t charged the male driver, who was found at the scene, with a crime. It’s unclear how the driver and the baby may have been related.

According to police, employees at a Waffle House spotted the baby around 2:45 p.m. in the car. After calling police, the employees pulled the baby out of the car, which was unlocked, and attempted CPR. Local reports say the temperature was around 98 degrees.

Coroners said the baby died of hyperthermia, or elevated body temperature.

Piston Slap: The Heat Is On!

Sajeev,

I am not a TTAC member, but I read it almost daily. I suppose I should join soon. Anyway having read your “piston slap: we need your help” post, I have one that has been stumping me for about a year now:

The car is an 08 Impreza STI. For the past year or so, the power steering struggles and whines. It is much worse when the car is cold, doubly so when the weather and the car are cold. There is no belt squeal. I have tried flushing and bleeding, both with factory fluid and also with the Lucas stop-leak stuff. Modest initial improvement only lasts a little while. Subaru forum posts suggest the STI cooks its PS fluid because the fluid lines route near hot turbo components. However it seems now even with fresh fluid, the problem persists, leading me to suspect a component has gone bad. I don’t want to drop over $600 for a new pump. Are there any tricks you know of, like for example, replacing a particular gasket? Or, better yet, some advice on narrowing down exactly what the culprit is (short of replacing the whole freaking pump)?

Thanks a lot and keep up the good work – I love the site and what you all have done with it.

  • Rochester "better than Vinfast" is a pretty low bar.
  • TheMrFreeze That new Ferrari looks nice but other than that, nothing.And VW having to put an air-cooled Beetle in its display to try and make the ID.Buzz look cool makes this classic VW owner sad 😢
  • Wolfwagen Is it me or have auto shows just turned to meh? To me, there isn't much excitement anymore. it's like we have hit a second malaise era. Every new vehicle is some cookie-cutter CUV. No cutting-edge designs. No talk of any great powertrains, or technological achievements. It's sort of expected with the push to EVs but there is no news on that front either. No new battery tech, no new charging tech. Nothing.
  • CanadaCraig You can just imagine how quickly the tires are going to wear out on a 5,800 lbs AWD 2024 Dodge Charger.
  • Luke42 I tried FSD for a month in December 2022 on my Model Y and wasn’t impressed.The building-blocks were amazing but sum of the all of those amazing parts was about as useful as Honda Sensing in terms of reducing the driver’s workload.I have a list of fixes I need to see in Autopilot before I blow another $200 renting FSD. But I will try it for free for a month.I would love it if FSD v12 lived up to the hype and my mind were changed. But I have no reason to believe I might be wrong at this point, based on the reviews I’ve read so far. [shrug]. I’m sure I’ll have more to say about it once I get to test it.
