Hi everyone and a thanks in advance for any helpful info as this is my first post! So basically I bought an 05 Subaru Impreza with a salvage title that is at 74k and both of the serpentine belts have been changed (or so it appears). The car has been sitting for almost a year and hasn't been driven much so I threw a bottle of Lucas to regain the lost torque and horsepower and now it runs nearly new. The guy at advanced auto parts also suggested that I throw in some Seafoam in there too since it had been sitting for so long after the Lucas cycled through. Could this hurt the engine at all, or just help clean out the engine?
My main question however is if anyone could suggest a mechanic in the Charlotte, NC area; since I don't believe that the timing belt has been changed. I was told by my mechanic that works on my Chevy Cavalier that it looked fine and should be good till around 90k miles. I frankly would rather just have it replaced and not have to worry about it in 15k miles since I travel for work. So I called around and the Subaru Dealerships in Charlotte and the cheapest wanted 700$ and they said that could change depending on what they feel needed to be replaced. The guy was nice and explained they replace the waterpump and also the engine timing belt tensioner as well when they do the timing belt. Which is understandable to me as I'm considering changing the AC-Belt tensioner after reading horror stories). The only thing that bothers me is that I don't want that 700$ to jump to $1500 which he openly admitted it could "depending on what they find" which is a red-flag to me for mechanics.
Also if anyone would like to suggest any other preventative maintenance I should do at this point I'm open to whatever suggestions you have since this is my first Subaru.
Many thanks in advance!
