I have a Dodge Journey and I'm about to do a timing belt service which replaces the timing belt, water pump, and the hydraulic tensioners. Now this is preventive maintenance, there isn't anything wrong with my belt, I just know it is a good idea to get a timing belt service every so often. As you are aware, whenever mechanic shops, especially well known ones perform services on vehicles they warranty their work. I'm curious what exactly that covers.
For example, let's suppose I get the timing belt service and it was done wrong and three months later my belt breaks on the highway. Suppose again I have an interference engine, which I think I do and the cylinder heads get damaged as a result of bad timing belt mechanic work. Would the mechanic shop warranty cover that?
I realize that is too broad, as there are thousands of mechanic shops, I'm asking for those who worked for a shop and would they have covered something like that or is the warranty just for the timing belt even though the poor mechanic job caused the damaged heads?
