Piston Slap: Cool Thoughts on Electric Fan Conversions

Hi Sajeev,

Back with a topic that might be real to many Texans and others of warmer climes. I’m close to 220,000 miles on my 94 Nissan D21. She’s still motoring along and I’m doing my to keep her maintained.

We’ve just come through the dog days. Back when it was hitting 112° in Dallas, I was finding myself stuck in afternoon rush hour traffic on 75 and the coolant temp was pushing upwards into a zone that definitely had my attention. Fortunately, the traffic cleared and I could get back up to speeds that moved sufficient air across the radiator.

  • Daniel J Cx-5 lol. It's why we have one. I love hybrids but the engine in the RAV4 is just loud and obnoxious when it fires up.
  • Oberkanone CX-5 diesel.
  • Oberkanone Autonomous cars are afraid of us.
  • Theflyersfan I always thought this gen XC90 could be compared to Mercedes' first-gen M-class. Everyone in every suburban family in every moderate-upper-class neighborhood got one and they were both a dumpster fire of quality. It's looking like Volvo finally worked out the quality issues, but that was a bad launch. And now I shall sound like every car site commenter over the last 25 years and say that Volvo all but killed their excellent line of wagons and replaced them with unreliable, overweight wagons on stilts just so some "I'll be famous on TikTok someday" mom won't be seen in a wagon or minivan dropping the rug rats off at school.
  • Theflyersfan For the stop-and-go slog when sitting on something like The 405 or The Capital Beltway, sure. It's slow and there's time to react if something goes wrong. 85 mph in Texas with lane restriping and construction coming up? Not a chance. Radar cruise control is already glitchy enough with uneven distances, lane keeping assist is so hyperactive that it's turned off, and auto-braking's sole purpose is to launch loose objects in the car forward. Put them together and what could go wrong???
