Took my 05 Tahoe for oil change and your mechanic found out there was a leak on the heater hose so it was replaced. A couple months later the vehicle kept losing coolant; took it in for you to check it out. You took almost a whole day and found nothing wrong with it. You stated that your mechanic did a pressure test and found no leak. You changed $39.00 for half hour labor. Next morning found a puddle of coolant on the ground. I started losing confidence of your shop so I took it to the mechanic shop next door to you and less than hour they found out that the connector of the heater hose was leaking. The worst part was the same heater hose replaced by you. Obviously your mechanics don't know what they're doing! Any comments?????
