We were told by two other shops that our truck had a blown head gasket! We brought it to Timmons just to make sure and to get an estimate for repairs. After Timmons checked it out thoughroughly, they told us that the head gasket is fine and does not need to be replaced. From this I figure that these guys not only know what they are doing but they are also honest. We intend to take all our trucks here for repairs from now on. 5 star service all the way! Thanks Timmons for being the last honest repair shop.
