    I absolutely love this workshop manual. All of the men in my life seemed to have absorbed knowledge about cars from the air. In reality, it was probably from their fathers, but my dad never saw to talk to me about cars. (Or screwdrivers) Despite my education, I was never sure what I was agreeing to for maintenance and I hated it.

    The manual has a lot of good information in it that I surely will use later. It falls short with OBD2 connectorm like other OEM workshop manuals.

    I’ve spent the past 50 years give or take working on cars, trucks and motorcycles (for only my own entertainment.) So much of the electrical was duplicating factory systems but when it came to really understanding the reasons for doing or using certain parts there was a void.

    I definitely was an auto airhead. I knew to get my oil changed on time and replace my tires in pairs but that’s about it.

    You don’t need a lot of math skills or highbrow reading and comprehension to understand and apply the information in this manual.
