When I bought my HHR I tried to find a Chiltons repair manual so I could keep the maintenance up on it but to no luck. So figured built on a Cobalt chassis a Cobalt book would work for engine problems. Much to my dismay so far I have found that something as simple as the air filter is not installed in the same manner as the HHR. Not sure what other lovely things I will run into trying to use the book. So I am definitely thankful for this forum.

 

PM me for info about a service manual. Not a commercial.
