    Does size matter?

    I have seen bigger filters on bigger cars and thought the oil filter on ours is adequate. 🤷 Those who use after market oil filters are usually familiar with the larger size that still fits. I have used all sorts of after market filters and while they all look about the same size on the outside...

    Grounding Cylinder Head Test Results (2024 CX-5 Turbo)

    Been driving around with 3 extra cables and still haven't obtained the readings yet. It looks like I am more muscles than brains. 😭

    2016~2023 CX-9 Transmission fluid level questions

    My car wouldn't start if the MAF sensor was disconnected. 😅

    2016~2023 CX-9 Transmission fluid level questions

    Yes, I reset the shifting pattern after filling with red fluid. Do you mean it doesn't shift right after your drain/fill with Aisin FZ, or that you aren't comfortable yet? 😅

    2016~2023 CX-9 Transmission fluid level questions

    My first drain/fill (on a 2017 CX-3) was with the wrong fluid, red Idemitsu M5. Within a week or two I did a second drain/fill with the Aisin FZ and two more rounds after that. Not sure what harm comes from the mix of old OEM fluid and red, they mix fine, no jelly or sludge. I didn't do a flush...

    How insane is a 140mph+ speedometer?

    I would have been ok if my speedo stops at 90. 60-80 right at the top, and nothing after 90. Give me engine temp or oil pressure in that space. 🤷

    2017~2025 CX-5 Cold Engine Oil Check

    It says to wait at least five minutes. I check whenever I want to, sometimes ten hours after. I wonder if this procedure is to make sure that the new oil gets into the new filter too.

    Coolant overflow hose

    Ideally the open hose on your overflow tank should point downward. If you keep the level below max in the overflow, there shouldn't be any excess coming out of it.

    Coolant overflow hose

    My understanding is that the overflow tank is the same thing as the reservoir. The radiator (under the cap with the PSI rating) becomes pressurized when the car is running. When coolant in the radiator expands and reaches a certain pressure, the cap allows the excess to enter the overflow. When...

    Grounding Cylinder Head Test Results (2024 CX-5 Turbo)

    Thank you ALL especially AL! Being in a warm climate, the wires are probably OK. I have put away the extra cables for now and will focus on driving. 😁

    So I changed my battery and my instrument cluster flipped itself

    I have never seen anything like this before. It sounds like you've done all that there is to do. I read that it might fix itself: 😬 I thought I included a Reddit thread about this problem on Hyandais. 🤔

    Grounding Cylinder Head Test Results (2024 CX-5 Turbo)

    While browsing broadly to learn, I came across grounding kits that are meant to replace factory wires, for the same reasons you replaced functioning sensors. So far the only factory grounding wire that I found to be stand-alone, is the cylinder-to-chassis on the passenger side. It looks thin...

    The discussion was so technical that I didn't know it was less than friendly. 😂

    How insane is a 140mph+ speedometer?

    My speedo goes from 0 to 140 mph and puts 70 at the top (12 o'clock). 60 at 11:55 and 80 at 12:05. It makes sense to put the range of safe speed at the top. 55 mph is for trucks and vehicles towing.

    What 5W30 oil brand do you use in your CX-9?

    I wonder what gave him the confidence, at 100K miles, to say no transmission service, and again and again at 200K, 300K, and 400K miles. Most people don't expect 400K from anything that is supposedly a "closed system" and "lifetime." 😅 He seems educated and diligent about other aspects of the...

    Grounding Cylinder Head Test Results (2024 CX-5 Turbo)

    I added one cable from the top skinny bolt on the alternator to the factory bracket (shared with factory cylinder-to-chassis cable). On the HKS Japan website, I didn't find simple kits like what are common here. They install a round plate on the battery ground terminal to grow an octopus of 12...

    Grounding Cylinder Head Test Results (2024 CX-5 Turbo)

    Thank you! With the clamp on meter, is 1 amp too low? A better connection point would read higher? Can I use this one with probes? Got it when I had electrical problems in May. When I monitored engine load in the past, the value was constantly changing. I recall that between the options of...

    Grounding Cylinder Head Test Results (2024 CX-5 Turbo)

    The alleged benefits and ease of installation convinced me to try. If you were my neighbor, I would have installed the wires for you already. Time is what I have. I assembled two wood models in two days like an addict. That's an expensive hobby because the models I want to build are priced over...
