I was wondering if it's hard to replace the timing and the water pump on a 02 rex or does anyone know how to do the timing belt? cause it looks pretty hard by looking at the timing belt assy post on scoobymods. http://www.scoobymods.com/forums/showthread.php?t=4573
its probably one of the easier cars to change the t belt...but are you nearing 100K? otherwise i wouldnt worry about it.
its never to early to change a timing belt....... that 100k that subaru says is really pushing the limit.... ok let me refrase that so people dont correct me....... if you drive your car hard at all.... it would be a wise choice to change it before 100k....... yes, subaru says that they will last to 100k..... do they always?.... no..... and plus the stock wrx timing belt will strech under stress when it gets up there in the higher miles which could throw your timing off and put your car slightly out of tune..... but i do agree that the wrx is one of the easiest cars i know to change a timing belt on...... get an spt sti pink belt ther a lil bit spendy though (around $250ish)
the timing belts are pretty striaght forawrd you just need to watch out because i think the ej20 is a interference motor meaning if the timing is off you might fry your valves. but thats also another reason to do it sooner. if it breaks your valves are toast. i would recommend that if you havent done it before do some reading on it, or watch some one do it the first time. just my .02
Take out your radiator/fans and it is a piece of cake. Just don't let your cam sprokets move much when changing the belt. If the valves hit each other, they'll bend. I'm not shure if the newer cars still use the hydralic tensioner piston, but on mine, you need to push it in SLOWLY, as in over the course of ten minutes or more. A bench vice works best, but a C clamp will do. Haynes manuals have good descriptions, with decent pictures, and can be invaluable when attempting something like this for the first time. You'll eventually find these cars are pretty easy to work on. Its one of the benefits of being designed with serious rallying in mind. The service guys for the WRC team can change their tranny in 11 minutes:eek3:
well....when you have the timing belt cover off......put the crank back on and crank it so the notches on the gears are UP and you'll be fine. Because then the pistons are all halfway into the block. Do you need a supervisor?
