Hi I am doing my own tune up and was trying to find tools that fit my 97 Volvo 850 do they sell them at Harbor Freight ?

 

What tools specifically?

 

Don't think there are any special tools - other than the serpentine belt tensioner tool (the Harbor Freight ones won't fit the 5/8th box - I got mine from IPD). For the general tune up you need a set of torx bits to remove the head cover, a deep spark plug socket with extension for the plugs, and a 10mm socket/screwdriver etc for removing the airbox(makes for easier access to the distributor) and the distributor cap removal. Note you can do the distributor cap without removing the airbox, but its a bit of a pain (I've done it both ways). Also a standard oil filter wrench works and the oil drain is a standard socket side (I think its a 17mm). If you are planning to do the timing belt, then you will also need a large torx bit (45T?) for the timing belt tensioner. Check out RobertDIY's videos on YouTube - he does a nice job of showing what tools are required at the start of the vids.
