Catalytic Converter

im not a techi with cars, so was wondering how often one of these needs changing, as well as the cam belt, if it does at all need changing? after how many years or miles the car has covered.

cheers

yaris uses a chain not a belt... both should serve the lifetime of the car... but cats often get changed along with the exhaust...

I cant remember exactly what it it is, but something in the engine, maybe timing belt, gets changed at 60,000 miles if it's a certain model.

Cat Converters need changing only when they fail....This will result in MOT failure on the emmissions tests. There's probably a recommended lifespan quoted for them somewhere, but if you're emmissions are ok then it's not worth bothering with. As far as the cat goes it's a case of 'if it ain't broke then don't fix it.'

And if it is broken and you pass, then scrap the bugger! Have it de-cat!

There was someone in the Starlet forum a while back who had the cat pipe fitted with quick release clamps, like the ones on a mountain bike saddle....so the car was de-catted for most of the year, then it's just a case of clip the cat pipe back on for the MOT !

......well I thought it was clever !
