Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
The Labor Time Guide calls for 4.8 hours to replace the timing chain (add 1.2 hours if the vehicle has A/C). It's not "that" bad of a job, but a lot of other items need to be removed to gain access- exhaust, oil pan, front cover, etc. If you have previous timing chain experience, this may be a job you can handle. Due to the year, the repair manual isn't as detailed as it could be... but I can give you what I have so you can take a look and see if it's something you'd like to tackle.
