January 7, 20251 yr Hello forum, Firstly, does anyone know if US and UK cambelts differ? Reason being that US WRX/STi models have mandatory replacement at 105,000 miles or 105 months which is I believe a legal requirement for US vehicles. Secondly, Roger Clark Motorsport recently told me that in addition to replacing the cambelt at UK recommended intervals, I should also change the cambelt pulleys. I've never seen or heard of this before so would be grateful for any insight that members better informed than me can provide! Edited January 7, 20251 yr by Forncett rotten English!
January 8, 20251 yr Most kits come with the pullies and water pump. EG https://navigates.gates.com/emea/v/subaru/impreza/powergrip™-kit-%2B-waterpump-%2B-thermostat/gates/kp2th15612xs-3.html
January 8, 20251 yr Author Thanks Linx, I've been recommended this: https://rogerclarkmotorsport.co.uk/collections/subaru-impreza-2006-2007-service-items/products/rcm-genuine-timing-belt-water-pump-combo-kit-2002my-ej20-22-25 which you will notice does not include camshaft pulleys that cost ~£200. With respect to replacing these, I'm informed elsewhere: depends on exact age but various cars use a Bakelite type material for pulleys and these can be damaged due to mishandling, etc......IMO its an inspection type issue rather than a requirement per se which should you need to replace these things raises the question, how to prevent the camshafts moving? There must be a special tool for this but I can't identify one?
January 9, 20251 yr Hi Forncett, I'm pretty sure I didn't need any locking tools when I did mine. However it was a few years ago. I did have to by a tool to hold the crank pully while I un-did and did up the crank bolt. Must be some YouTube videos on the subject. Linx
January 10, 20251 yr Author Hello Linx, Thanks for this: do you need to undo the crank pulley to change the cambelt? Kind regards & have a great weekend, Forncett

Kind regards & have a great weekend, Forncett I think you must do. I wouldn't have bought it otherwise. Get yourself the Haynes workshop manual. It's all in there.

Ah yes. That looks familiar 😂
