Mechanical or Hydrolic Belt Tensioner - how to find out?

Guys
Is there a way to plug your vin in somewhere and find out if your belt tensioner is hydrolic or mechanical? I forgot to check this morning before I left for work and now I'm chained to my desk for the next few hours.

Thanks!

Probably not, your best bet is to open your hood and remove the fan or remove the splash plate under the car and peer up. Take a pic and we'll tell you what you have.

No. U just have to do a visual inspection. Look up the mech and hydra parts on the internet for pix. Then open ur hood and see which one u have. Problem solve
