If you’re going to do any serious engine, drivetrain, or suspension repairs I would recommend a factory repair manual if you can afford the $200.00 price tag. I have compared a factory repair manual to Haynes on Chevy Astros and I found serious incorrect information on front suspension disassembly procedure that not only doesn’t work but damaging the front coil springs. The authors of these books seem to presume one size fits all ( or in this case all front coil spring suspensions are the same) As far as this repair manual for the HHR they have left out views of the engine compartment with the sheet metal body parts removed or drawings depicting areas that can’t be photographed easily. They use to include this in their older manuals. Also in flipping through this book I noticed several Toyota pickup photos standing in for the HHR regarding cleaning the engine. Once again This is probably due to that pesky sheet metal that with the large air filter housing completely covers the engine.
I always use Haynes Repair books. It was getting hard to find this book since they stopped making HHRs but like always the sellers on Amazon don’t disappoint. This book is great quality and always making repairing vehicles a breeze. Anyone can do it with these books. Thanks Haynes for what you do! Keep it up!
This is the first book I have ever had that has no diagnostic information in it. Others have information on how to check parts to see if they are good or bad.
Considering that the factory manual for the HHR now costs $200, this is a bargain. All the average owner will ever need. This manual covers the things that most owners will attempt on their own and has many illustrations. I have many factory manuals that I have bought over the years. Most of the information in the factory manual is not needed unless you are a professional mechanic dealing with the car daily.
Anyone who does all their own maintenance or just wants to back up what mechanics tell them will find this book more than just useful.
I have only used it once so far. It was good to me on that repair. Harder paper would have been nice.
Finally found this book that is a great reference manual for any DIY. I had been unable to find it locally going back to 2007. Immediately was able to find what I was looking for making the routine maintenance procedure much easier and quicker.
