If you have the Mazdaspeed 3 this book does NOT have any coverage of this vehicle. There’s no mention of turbos, intercoolers, or any model specific items. General maintenance might be ok, but it doesn’t show you how to remove the turbo or intercooler to get access to what’s underneath.
If you have a Mazda 3, then this book will be just fine like any other Haynes manual.
The owners manual doesnt tell you everything about the car if you need to know how to perform some types of maintenance. This manual will allow those that are mechanically inclined to do routine and not so routine work on on whatever vehicle you buy it for. It is also cheaper than what I would have paid if I bought it at an autoparts store.
Do it yourself is almost a necessity in today’s economy, buy this book !! Just the maintenance info is worth it!!
If you have a Mazda Speed, this isn’t for you. It doesn’t cover supercharged engines. I recommend mazda247 for turbo questions.
Otherwise, this is a fine product for basic “how to” on your Mazda.
I’m a professional mechanic and I know the value of having a good shop manual when you’re getting “down and dirty” with a car or motorcycle. Normally, whenever I buy a new car, truck or motorcycle for myself, I buy the OEM service manual to have BEFORE I need it. But when I bought my 2011 Mazda3, I found that the OEM manual costs hundreds of dollars! That is just nuts. So I caved and bought the Haynes manual instead. It wastes too much space with generic mechanical information which applies to every vehicle on the road, as opposed being specific to the Mazda3. That info may be helpful to a total “newby”, but it’s a waste of paper and ink to an experienced wrench and it occupies too much of this book, leaving too little real, in depth, model specific information to rate more than a few stars. But it is better than nothing and a LOT cheaper than the OEM service manual.
I’m a big fan of Haynes Repair Manuals, but I was a little concerned when I looked at picking this one up for my 2010 Mazda 3. You see, in 2010, Mazda redesigned the 3 virtually from the ground up – it was a FULL model redesign. Often, when this happens, Haynes releases a completely new manual for the new model (e.g. 2010+) instead of just slapping the entire run of the car together. I took a chance and ordered the guide.
Haynes impressed me once again – this book deftly describes the differences between the 2010+ model of the 3 and the 2004-2009 model; it truly covers both series of the Mazda 3.
It’s worth noting that another user mentioned the book doesn’t cover the Mazdaspeed version of the 3. Since I own a i Touring, this didn’t affect me at all, but if you own a Mazdaspeed, take heed of the note.
This manual has a lot of info for a person that’s not a mechanic. Enough to do most at home repairs.
I have had Haynes shop manuals before. They are good reference material. The photos are very helpful. Will get one for my next car.
Bought manual for reference when working on a 2010 Mazda 3i as manual’s description says it’s covered therein (2004-2010).
The Manual appears to be a ‘general’ service manual with specifics to the 2010 model absent. Questions about specific scheduled service items listed the 2010 “Owner’s Manual” are not shown in the Haynes manual.
I’ve found that there are better sources on the web/you-tube for specifics and that this manual can be put aside.
This is a great detail book, and hope in the future it can be color printed and have the arrow to point out some detail parts that a non-mechanical person can easily to follow it. Overall speaking, a good book to recommend to the Mazda3 owner who like to get the car fixed by itself.
