I may not be a mechanic but I am a Mechanical Engineer. So, to make a long story short I will hit the high spots.I bought an 03 Durango to pull my camper.
It was running hot on my first trip. I drained and flushed the radiator. Bought the "correct" antifreeze. I was going to change the thermostat while the radiator was empty.
I found the bottom bolt on the thermostat housing was stripped. I filled the radiator up and took the Durango to Pep Boys. I asked them to simply take out the stripped bolt and put a new on in (I shouldn't have to give them and explanation). So I explained the car is running fine since I put the correct antifreeze in (G05 HOAT, Zerex).
I don't think I need to change the thermostat after all, but I may need to in the future. He kept telling me I needed to change the thermostat. I said no, then he said it would be a minimum of $60 just to try taking the bolt out. I said no, I will do it myself later.
I asked them for a tire rotation and alignment since I was there. They called me and said I had a flat. It will cost $25 to plug it. I told them to fill it with air and I will plug it myself when I get home (most places charge $8).
He then told me that you have to plug a tire from the inside. I actually laughed and said are you serious??? Do you really think I am that lost here??
Then they called me back later and said the stud was seized and broke while trying to take the tire off. Just seems a little shady that the whole visit was spent with them trying to rack more money outta me with lies.
