It's not that difficult and can be done in as little as two and half hours. I used to live right next in Bedford Mass. I would have gladdly helped out but alas no in area.
Can be done with simple common handtools that average mechanic has. Recommend reading thru it twice to familarize yourself. Clean the engine well in all areas around the front engine compartment. Clean work area makes for less mistakes.
Get the whole kit. Timing belt tensioner and belt and water pump at the same time. Might as well do a coolant flush also prior to summer so have needed bucket to catch coolant.
Also a good time to replace the cap and rotor since you will have hoses off. Fan Clutch? Belts for AC and alternator?
Leave car sit over night so It's cool to work on in morning unlike getting a vehicle that has been driven to shop that hot to touch.
Good luck shouldn't take more than 4 hours for an amatuer and if need call some one from the Boston CCA as they are great like that.
