No it is not. Just takes time. No gaskets required. I bought an OEM belt but aftermarket belts cost less.
Subaru OEM # 15208AA024; Fram # PH3593A; Puro # L14460; Wix #51334.....
monroe or gabriel I'm a big fan of KYB. If I remember right, that's Subaru's OEM supplier.
It has a timing chain. I have the OEM service manual for that year Bonneville, and it shows a timing chain.
order new belts from an OEM supplier with new bolts and washers. remove rear seat and go to work!
The cam sprockets have marks, triangles on them near one of the teeth. These are lined up with notches in the rear cover for the timing belt. Some crank sprockets have two marks, one to align with the mark on the block, the other to use to match to marks on an OEM timing belt. After market belts don't usually have this mark.
Genuine ones would be manufactured only by Toyota or companies they contract with to make them for Toyota. These belts can only be bought through Toyota authorized resellers (e.g. dealerships). But there are other companies that independently manufacture them to Toyota's OEM specifications. These belts can be bought at most auto parts stores.
The front camber for a Subaru Liberty should be -1.0 degrees. This should be max while being even left to right.
Depends on the year, most people like to use the OEM extra s
Your better off with OEM parts
Like most manufacturers, Subaru puts different batteries in depending on the equipment installed. They may even switch specifications and manufacturers from time to time without telling anyone.
OEM recommends every 75k miles. I have 170k on mine and have not had a problem.
