Also battery failed load test. I’m so happy to hear it’s just the new SkyActivG engine! You made my month!!

Fantastic video. So glad I stumbled across this. Coming from a German vehicle, I was concerned about my brand new CX5, and why there were so many random loud sounds and high revs at a cold start up. So glad to learn that this is normal function of this manufacturers engine. The mechanic had indicated as such, but I was skeptical.

2 things make this engine loud, the steel timing chain (more durable and longer lasting than a rubber belt but louder) and the incredible 14 to 1 compression ratio (this is more than a few race car engines and provides more power).

Many thanks. Best explaination on this issue.

Really good video. Excellent description, sound quality, and camera work. This puts my mind at ease. After reading several forums I got a lot of different answers. This finally clears it up. I do have a couple of questions. 1) Should the fuel pump still make that sound at idle speed after the engine is warm 2) Does it quiet down at higher rpms or does it just speed up, making it harder to hear? Thanks again.

The high pressure pump gets quieter than what the video portrays when your engine is hot. (10min after the coolant temp reaches it running temp at 95c) When it is still cool it is a tad bit louder in my experience

really nicely explained! thanks

Thank you for sharing this!

These Mazda Sky active engines are literally bullet proof. I rented a 2014 Mazda 3 with 290,000 km on it and ran fine. Drives like new! I was so impressed with it and I bought a 2018 with 60,000 km and it's doing great. Love this car and will keep it at least for 10 years.

I have a 2012 mazda 3 skyactiv with 176k kms. It makes the exact same sound and rattling but only for a minute and then it lows down abit.. Thanks for this video!

This was so helpful 👍

Most modern 4cyl engines with direct injection sound like higher revving diesels. It's the injectors making the diesel style clatter. My mom has a 2012 Chevy Equinox, sounds the same way. First time I heard it I thought it was a diesel.

I have been worried for so long about that slight rattling noise during warm startup, glad to know it is normal thank you

Thanks for this video!

FIY the clicking noise at the 2:20 mark is coming from the vacuum pump not the fuel pump. In general, sound in a direct injection engine is mostly generated by clicking injectors (as the solenoid within needs to overcome a very high fuel pressure). In mazda’s case they have added a vacuum pump for the brake booster, as scyactiv engines do not generate vacuum at idle, and it is the primary source of the clicking noise you hear

@Driver67

3 жыл бұрын

I have to disagree and agree with you. The high pressure fuel pump does cause the clicking as it is directly cam driven. The vacuum pump is in fact located beside the high pressure pump but I do not know how much operational sound the vacuum pump makes. When it is very hot, the high pressure pump location does make lesser sound than the injectors. The high pressure pumps on the Mazda DISI engine does make quite a bit of clicking as well but the injectors on those are usually louder.

Very well done, thank you.

The sound is from the high pressure fuel pump and brake booster/ vacuum pump that run off the exhaust cam .

It sounds similar to my Mazda 2's engine. At first, I thought there was something wrong with the engine but after watching this, I feel a bit better. Anyway, I have my car service coming up next week and hope the mechanic can give me a good news!

Great Video! Thank you.

High compression engines will give you that ticking sound on startup. My 3 does it before settling down to a nice little burble. My VVT-i Corolla did the same thing.

Great video, very interesting and helpful. My European Mazda 3 2L 150 sounds a little different and seems to rev a higher at start (maybe because it's brand new).

Actually, just as an addendum these types of quite loud cold start noises are fairly common these days. Even an old 2007 2.0 litre Hyundai i30 with the G4GC engine is amazingly diesel-like in sound on its first cold start of the day. Lots of loud clacking in the Hyundai mainly attributable to solid bucket tappets makes it sound exactly like a diesel for the first 15 or 20 seconds. So the Mazda SkyActiv is actually quite a sweet and smooth sounding modern engine. No worse and actually quite a bit better than most but still fairly typical in the type of noise its making. Good reliable motors that someone elsewhere mentioned they had put nearly 400,000 miles on (nearly 600,000 km) in their 2015 Mazda 6, so that's good news

Thank you very much for this video

Really helpful thank you

We bought new the 2017.5 Mazda 6, 2.5L Grand touring. We love the car but I have not been a fan of the way the engine sounds. Thank you for outlining what and why it sounds the way it does and that it is normal.

I own the same car for 3 years and I think it's normal sound while cold weather. Don't worry.

It sets the ignition timing to -20⁰ (or 20⁰ ATDC) to speed up engine warm-up, namely the exhaust system. It doesn't do it as long in warmer weather. There is a TSB on it. A small amount of noise (like piston slap/valve noise) when cold, that stops when warm, is normal and OK.

Yeah I noticed that the engine always sounds really loud on a cold start but then quiets down after a few seconds. And if I restart the engine shortly after turning it off again, it goes straight to the quiet phase.

That's Oke, don't worry!Can be the belt tensioner and water pump cause attach outside from the engine, those can make noise.Just normal running sound.No engine light, that is the most important thing

The sound better when you modified your exhaust and every morning you always get excited to start your car in the morning and your mood will turn good

also be sure that the engine cover is on correctly, if not the vibrations will make it shudder and make you think you have a head gasket issue

Awesome video - thanks for posting. I've known about the high revs during cold start - but was not aware of the retarded timing to allow gasses to heat the catalytic converter. The car does warm up super fast. I can feel heat warming the cabin in less than one mile after startup. Gas mileage is amazing on these engines.

Mazda's Skyactiv petrol engines are the first I've seen, that if something was going wrong I wouldn't be able to hear it - no matter cold or warm. They don't sound nice (idling under the hood at least) but as far as I know they are very reliable.
