I assume you checked to see if the oil filter is tight since it's on the passenger side of the car and on the bottom side of the car where the oil is.

My small OBD scanner has a temp1 and temp2. As far as I can tell, temp1 is the engine coolant temperature and temp2 is the coolant temperature leaving the heater core as measured by the sensor on the heater hose "manifold" on the passenger side firewall that both hoses attach to. Monitoring...

These low levels from the factory aren't something recent. I've been on this board for some time and remember reading about this IIRC 6-8 years ago, maybe longer. Then there's the discussion about underfill of transmission fluid, coolant (low overflow bottle level) and engine oil level on the...

Yea, check out the one's about the old veteran being harassed by younger military dudes. Some of these "feel good" videos are enough to gag. No warm and fuzzy feelings here. LOL

You bring up a good point about the "heart attack" and I've had (or installed myself) gauges in some prior vehicles, so I'm not criticizing your choices. And I've actually thought about adding some sort of readouts for different parameters(engine and trans temps and oil pressure being the main...

I'll plead ignorance here as I don't remember much being posted in the past. My understanding is that some (must be a minority I'm guessing--never see much about it anywhere else) heater cores plugged and Mazda attributed it to corrosion and increased the amount of "something" in the revised...

Going by the headline it seemed the usual sensationalized youtube stuff but then it seemed plausible after listening to the reasons. Guess I'm too gullible then. Welp, gotta go buy a bridge some guy wants to sell me. MODS: delete this if you choose so as to not waste members time clicking on...

Saw this and decided to post this as we drive ( or consider purchasing) other brands) beside Mazda. Right up front --- Mazda is not included and after viewing this we should feel fortunate we own Mazda. The scary part mentioned is that these models can't be registered/registration renewed...

Never gave it a thought. I drained a full gallon from the radiator petcock before changing the hoses.

I don't know either and I'm not particularly concerned for the following reasoning. Last summer when changing the thermostat and radiator hoses, the 4 year old Zerex from the previous service was clean and no buildup/deposits inside the hoses either. Prior to that ,the original factory fill was...

Can't see the coolant making any sort of difference in operating temperature since that's the thermostats job and have no idea what the coolant temperature is at any time unless I plug in my scanner, which isn't very often. Don't have any gauge readouts of any sort other than what came stock on...

I've always gone with servicing the coolant to the bottom of the filler neck on level ground after any air is worked out of the system. Which means checking the level cold for the next few days as operation works the air out and adding more if needed. The constant cycling of coolant back and...

First thing I'd suggest is a new radiator cap. Yours is 9 years old if original. If for no other reason it's good insurance. You didn't mention any leaks but I could see that a leaking radiator cap can allow coolant to slowly "boil away" causing a low level in the radiator. When cooling down...

Last year I pre-emptively replaced some cooling system parts on my 2014 at the 10 year mark. I used Mazda radiator hoses and thermostat. Thermostat was a chore and chose Mazda part because I don't trust aftermarket for such a critical item. Not worth risking overheat/engine damage. The original...

Your MINI no doubt had a heater valve the opened to allow hot coolant into the heater core. The displaced colder coolant then caused the temperature to temporarily drop as you have stated. Our Mazda's (and probably all newer cars) lack a heater valve and coolant is continually flowing through...

I agree with the above posts about changing the gasket. It's good to have one available if there's a problem, that's why I got one out of habit. I'm not specifically recommending to reuse the old one but only that mine could have been if needed. Had no indication of it leaking beforehand. It was...

To answer your question, it's the piston seal (in the bore) that retracts the piston. The seal has a square cross section (as opposed to a round cross section in an o-ring) that distorts when the piston extends and then reverts to it's square shape pulling the piston back (it's only a tiny...

I cleaned my 2014's throttle body about 5 years ago and replaced the gasket only because I already had purchased one ahead of time. I bought a Beck-Arnley brand online for just a few bucks and it was identical, I mean identical (including made in Japan) to the Mazda one that the dealers wanted...

The guy at the parts store (always a source of trusted professional wisdom ---sarc) was half right in the sense that there's sufficient grease if the pins pop out and aren't binding. But the other half is that the air still needs to be burped out by lifting the edge of the accordion boot. You do...

The threaded hole in the rotor typically takes a M8-1.25 bolt (8mm diameter with 1.25mm thread pitch)to act as a "jack screw" to loosen the rotor.
