    Warranty extension for fail-safe thermostat

    They call it water temp sensor. 😅 18840C. One is on the driver side of the engine near 15-17Z the water control valve. The other is on the passenger side near 15-010 the water pump. I may be looking at the wrong diagram though, there are variations between US/Canada and Mexico, with or without CD.

    Warranty extension for fail-safe thermostat

    Can you look up coolant temp sensor on the parts diagram for your CX-5? That's how I found out that the second value (for CX-3) was for the radiator.

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

    I thought he was really asking. 😅 Somewhere somehow there was a post or video saying that grounding to the transmission made a difference. I get the level of frustration tho. I am currently all the way up to my forehead in car troubles.

    OBD2 faults all over the place?

    I saved the list but didn't clear the codes while driving. They just went away on their own. The one for access system is saying that my key fob battery is low. Other apps (OBD Auto Doctor & Piston) didn't find any DTC. I can try a different dongle tomorrow. 😳

    CX-5 Battery Replacement recommendation?

    I checked my order history with AutoZone and it was a Duralast Gold/Flooded that I got in 2023. I recall not wanting the same one even if covered under warranty. It is either the Redtop at O'Reilly or Duralast Platinum AGM at AutoZone. 😵‍💫

    I think he did join us on the journey. He was first to advise me not to clip onto the chassis. AL are you ok what's going on? 😂

    CX-5 Battery Replacement recommendation?

    Are you still happy with your RedTop? I am planning to pick one up from O'Reilly's tomorrow morning. The OEM battery went out after 6 years. Then a Diehard from AutoZone started leaking after 2 years (it had caps on top like the EverStart Max.) Now the Mighty Max from Amazon fails to hold a...

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

    Thank you I will try again. Still need a new battery though. Soon after the maintainer was disconnected, the level fell to 12.0 (from 13.6) in less than a minute. I haven't had good luck with batteries after the OG died.

    No. More folks here are familiar with the multimeter like how familiar I am with chopsticks. 🙆

    OBD2 faults all over the place?

    Folks, are we not supposed to scan for codes while driving? I am getting a long list of codes in the OBD Scanner ELM Pro app. None of them triggered a CEL. Nothing comes up once the engine is off. Here's a list saved from one of the drives. Don't know what to think when something is stuck on...

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

    Quick question, to test for parasitic draw, must I disconnect every accessory including the OBD dongle and keep the key fob 10 ft away? I struggled for 30 minutes and couldn't get a reading after trying every reasonable configuration. The multimeter flashed a number once, when a car passed by...

    Here are some old-school clues from Haynes Manuals (NA/1998 and scooter/2014). 😅 Is there a new set of photos for plugs off Skyactiv engines?

    Warranty extension for fail-safe thermostat

    My understanding is that the temp in the engine block stays high unless/until cooler liquid is mixed in from the radiator. The radiator, on the other hand, is equipped with a fan and fins to cool itself down to near ambient temp. I don't understand how the engine temp would drop to 175 at any...

    Warranty extension for fail-safe thermostat

    Is that OBD Fusion? OBD Scanner shows two. Seeing how the two values fluctuate gave me a better sense of the system's health. I also have a rad cap that shows the temp.

    Thank you for your reply! Since no one else is playing, I will. My lay-person guess is it's F, fuel delivery issues.

    I don't know enough to play but am eager to learn. It sounds like you have eliminated battery/alternator as possible culprits. May I ask why? I was chasing a persistent misfiring in #2 cylinder on my R56. A MINI mechanic went to great lengths and determined that it must be a hairline crack in...
