  1. Living in Florida, my windows are always up and A/C on. But I will check the airflow next time I drive the car.
  2. After 5 months of driving the Spark with tinted windows, never been stopped by a cop. As I explained in a previous post, I used darker tint for 2 rear windows and a lighter tint for front 2 windows. The tint film has not come lose even after rolling the windows up and down several times. Before this glued on tint film, I was using a screen attached to the window with a suction cup. But that was no good when window needed to be rolled down, and had to be detached every time.
  3. Is your A/C system checked out for normal operation? Is there enough refrigerant in the system? Is the compressor functioning properly? The belt which drives the compressor in good condition? I am in North-East Florida, and it is 90+ high every day now with lot of humidity. My 2017 Spark is always parked outside and the A/C keeps comfortably cool inside. When first getting into the parked car in sun, I turn up the blower fan one notch higher, and after a few minutes it is down to minimum blower speed.
  4. Thanks for clearing that up, since I have not opened a car manual in 20 years. Without actually studying the mechanics of how the friction bands work, my guess is they may not be transmitting full load of moving the weight of whole automobile from standstill to match engine speed in the next gear, which is what the clutch in a manual transmission has to do. I am amazed with all the cars I have owned and driven from new to 100k miles, never had a problem with the automatics. I think even the A/C has a mechanical clutch to engage and disengage. That is why I avoid engaging A/C at high motor RPM. Because engaging the compressor load through the clutch at higher RPM's has to be harder on the clutch.
  5. lol I wanted something on top of the hood so I can see where the end of hood is. When parking, I have a hard time guessing where the front of car is. I can not see the front end of hood because it slopes down so much. So my purpose was purely functional. And no racing stripes or fancy hub caps for my Spark...I want the car to look inconspicuous Anyways that hood ornament does not look bad and it was cheap on eBay.
  6. Let us hope the new design is a genuine improvement. I never had to design any plastic components during my 23 years working for an outfit which designed and manufactured machines subjected the most brutal loads in machinery world. So I know nothing about designing parts made from plastic. But physics is physics no matter what material is used. Our machine structure was put together by welding together mild steel plates upto 12" thick. One category of machines we designed and built were cold extrusion presses. You start with a cold rolled steel bar and whack it between 2 dies made of tool steel with such force that the cold metal becomes plastic and flows to take shape of the dies. The impact forces generated on the welded steel structure of the press are unbelievable. Now that you understand where I am coming from, one thing I always avoided was to avoid any critical welded joint to bending stress. Bending stress during each cycle cause alternating tensile and compression stresses and that is a short cut to fatigue failure. I always strived to design any welded joint with shear stresses (instead of tensile stress). Looking at the coolant overflow tank the return hose is attached to the horizontal nipple of the plastic tank. Which means every bump the car hits will cause bending stress on the plastic nipple extension from tank. The designer had 2 options..either beef up the plastic enough to lower bending stress below fatigue stress level..or design the return hose coming in from the top which will minimize bending stresses in the plastic. Just my 2 cents worth. Incidentally our largest customer for our machines was General Motors, who used them in mass production of metal components for the their automobiles.
  7. I had frequent problems with clutch wearing out and throw out bearings wearing out on manual transmissions. DO not recall a single problem with automatics in all the cars I have owned. The automatic transmission is basically a fluid clutch and fluid does not wear like 2 friction disks rubbing with each other.
  8. Me too. Within my family have Owned 12+ different new cars and 6+ used cars, but never had a coolant tank leaking or cracking. Can't believe the designers do not learn from history or try to cheapen the design to save a few pennies.
  9. Eric, if children are NOT traveling in front seats, the airbags are not an issue. The problem is not that the airbags won't deploy, it is opposite. They deploy with too much force for a child in front seats.
  10. If your power train warranty is alive, by all means have the dealer fix it. Any GM dealer can repair it, if under GM warranty. I prefer local Cadillac dealer because they have better customer lounge and free breakfast.
  11. Thank you so much old gear head, for your service! I come from a family of career military, but I skipped the chance. Career & marriage issues took precedence. Yes, do not give up a car which works as good as you describe. Never divorce a working car or a working wife hehe. I retired early but wife worked full time for 15 years during my retirement. Gave me lots of time to play golf haha. I am encouraged to hear Spark power train can last with proper maintenance. So far I have zero issues with my 2017 LS. What I like the best is instant response to gas pedal operation and the very precise steering. The gas mileage is not critical for me since I put on only 600-700 miles in a month, but it is nice to fill up for less than $15.
  12. dear RoG, I know my memory is no longer what it once was, but I do remember that 1967 snowstorm because many of my co-workers were stranded at work place for almost 2 days. My own car (1964 Corvair) got me home but then the snow drifts buried it for 7 days until city crews plowed our street. I traded the Corvair for a 1967 Chevy Impala in early 1968.Here are some pictures and links.. "The Chicago blizzard of 1967 struck northeast Illinois and northwest Indiana on January 26–27, 1967, with a record-setting 23 inches (58 cm) snow fall in Chicagoand its suburbs before the storm abated the next morning. As noted in 2016 and 2017, it was the single greatest snowfall in one storm in Chicago history." The Chicago blizzard of 1967 struck northeast Illinois and northwest Indiana on January 26–27, 1967, with a record-setting 23 inches (58 cm) snow fall in Chicago and its suburbs before the storm abated the next morning. As noted in 2016 and 2017, it was the single greatest snowfall in one storm in Chicago history.[1][2][3] As the blizzard was a surprise during the day with people already at work or school, it stopped the city for a few days as people dug out. "The storm was a full-blown blizzard, with 50 mph-plus northeast wind gusts creating drifts as high as 15 feet."
  13. I have problem with rear seat headrests blocking some vision through the smallish hatch window. I should just remove them. The kids are grown up and gone, so back seat is used more for placing groceries, left overs from restaurants, beach chairs etc. I have no issues with front seat headrests. The front seats are more comfortable than my previous car.
  14. But does your grandma's Equinox have a hood ornament? My Spark does (see photo above)
