Anyone know where I can download a guide on how to change an Impreza cambelt ?

Two things any guide won't tell you:

One: how to undo the crank bolt (normal thread). Nut runner or a long arm against the passenger's side chassis rail with assistance from the starter motor.

Two; double checking the timing/belt alignment using an old car door mirror glass, if your paying attention, its quite easy to get it one tooth out once its been tensioned.

 

Thanks mate

 

I should have mentioned the engine is now out of the car.

How do I undo the crank bolt with the engine out then ? Special tool or something ?

 

on a spare that I have I jammed the flywheel, its not easy to do when sat on a pallet!!

 

In hindsight...next time undo the crank pulley with the engine in the car connected to the gearbox, handbrake on hard, 5th/4th gear and a LONG breaker bar.

Otherwise your only hope with teh engine out is decent impact wrench, or find something to jam the flywheel so you can use the breaker bar.

 

So it might be easier to fit the engine into the car,then change the cambelt ?

 

Its only marginally easier to remove the pulley with the engine in - that's all....its easier to replace and time up the belt with the engine out. So its a no win situation.

Find someone with an impact wrench if your truely stuck.

 

i used a 1/2 inch extension bar on the flywheel side to jam it. Then lots of presure on the pulley side to loosen it

 

any chance i can get a copy of this please m_cox_80@hotmail.com
