    Change spark plugs strictly by mileage?

    I changed mine at the 10 year and ~71,000 mile mark using the NGK plugs. Even though the original plugs looked good and the gap was basically unchanged, the idle became smoother and the throttle response improved. Glad I changed them. It was also a good time because I changed the valve cover...

    Fuel Rail Pressure A Reading 1440.22 psi at Idle

    Without checking, I'd think that wouldn't be too high if the fuel has to be forced through tiny injector orifices with enough pressure for it to be atomized against cylinder compression pressure. I know my 2014's fuel pressure can reach ~2900 PSI (which I believe is the max spec) at high rpm...

    2013~2016 AWD CX-5 Replacing Rear Shocks - Questions

    The studs I'm referring to are the one's that fasten the BOTTOM of the shock to the knuckle not the top. Take a look at where the bottom of the shock mounts to the car. You should see a big nut and the tip of a stud that will accept a small hex socket to remove /install the stud. My...

    2013~2016 AWD CX-5 Replacing Rear Shocks - Questions

    I didn't see what model year the OP's Cx-5 is but mentions 12 years so I'll guess 2013. My 2014 was built in 9/13 and does not have a bolt retaining the bottom of the shock ( although service manual shows bolt)) but instead has a stud threaded into the knuckle and a 19mm(?) nut. I think the bolt...

    New 2025 CX-5 with highway vibration problem; tires?

    I had those Geolandar's which came on my 2014 when purchased new. I grew to hate them and they were gone at 3000 miles. The good: decent ride and good handling on smooth roads. Good dry traction. No heavy rain to check hydroplaning. The bad: rough road really harsh ride and they wore quickly. At...

    What the heck happened in my engine bay?

    How should we know. I mean ,really, is something this trivial even worth taking up the bandwidth to post and expecting answers.

    Valve Cover Leak

    Was it an actual leak or just seepage that develops given enough time. Did you actually see it beforehand and where was it located? With normal seepage that really isn't much more than a smudge that can be wiped off and takes a long time to reappear, some dealers will call it a leak and quote a...

    2013~2016 CX-5 Rear shock removal question

    Good writeup! Handy info to know. Thanks for posting. Do you think it would be possible to loosen the stud/sleeve (after rubber removal) with a pipe wrench. Also, maybe the possibility of using a "twist" socket on the end of the stud and an impact wrench. Would appreciate your thoughts on these...

    Check your rear shock mounts

    Are they even available separately as a genuine Mazda part?

    TPMS light keeps coming on when I start the car

    Check to see if the valve "core" inside the valve stem is screwed in tight. In fact check them all. Air can still leak out even if the little cap is on the valve stem.

    Car says it's overheating but it's not overheating

    It's best to use OEM factory sensors (MAF, IAT,O2,ECT, etc). Although more expensive, the aftermarket sensors can be a crapshoot. I'd hate to have a defective cheap sensor not alert me to an engine overheat or cause other problems. Source them cheaper online from a Mazda dealer. Mazda's are...

    CX-5 Battery Replacement recommendation?

    I'll second all of the above recommendations for the Walmart Everstart Maxx. Much better price for a lead-acid than the auto parts stores. My Costco won't even remove the old battery and install the one they just sold you. I said to them" what about if some little old lady needs a battery". The...

    Cabin Filter = Gross

    Three years! One year max for mine and more like 7-8 months. No charcoal versions. Every one I tried restricted the airflow too much. We all do whatever works for us. And yea, you're right. That is nasty. LOL

    Car says it's overheating but it's not overheating

    Engine won't even be warm yet after only a minute after starting. It takes time to warm up hundreds of pounds of metal much less get it to overheat temperature. At that point it wouldn't be water pump related if it ever was. I'd guess sensor or wiring/ electrical connector issue.

    Engine does not cool down when parked overnight

    How is the "diagnosis" going to proceed further if the OP is afraid to even quickly touch the engine for themselves. Feels like a lot of "wheel spinning" has gone on already. Also feels like we're being led. This thread has gotten ridiculous.

    What have you done to your CX-5 today?

    Agree on the lack of a glove box light. Some other annoyances due to Mazda's cost cutting are the lack of window switch button lighting except for the drivers window. Also no courtesy lights on the front floor foot wells or at the bottom of the door panels. The cargo area could have had more...
