We were trying to replace the heater core, the instructions were foggy to say the least. Further repairs or maintenance just as foggy, its a good book if you have a lot of experience with repairing the vehicle and don't need a how to. Amazingly the "Ford Tempo Mercury Topaz 1984-94" book by Mark Christman, which is by the same company, was a lot better for repairs and maintenance. But neither book helped with replacing the heater core, we eventually used other resources for more ideas on how to actually get to the heater core to get it out.

I've used this book for nearly three years now, and keep wondering why I go back to it. (Actually, it's because it's the only Tempo/Topaz book I own.) I have found several major errors in the illustrations, usually due to showing a 2.0 engine setup as a 2.3 or vice versa. Some instructions, like how to change a water pump, are just plain wrong. Electrical schematics, particularly of the instrument cluster are sketchy to the point of being useless when troubleshooting anything other than a hard failure. I suspect that much of the text in this book was a quickie cut-and-paste job of info that pertained to these same components as installed in other Ford products. It really doesn't do justice to the model-specific problems of navigating the limited space of the engine compartment or tracing an intermittent electrical circuit. Proofreading was spotty at best. It's better than doing a repair job blind, but not by much.

Chilton's Ford Tempo and Mercury Topaz Repair Manual 1984-94 is not for the average car owner. It is probably not even for the average mechanic. It is written in difficult language and at times seems to display unnecessarily complicated methods of performing simple tasks. From beginning to index it offers low quality information and instruction. There are too many diagrams and not enough photos. The photos available are poor. Overall this book was not very useful to me. I have used the Haynes manual for the same car and found it much more useful.
