Mk3 Cat

[Guest snel81]

Does anyone know if the mk3 on a B reg has a cat converter heard that older cars didnt have them an that there not needed for the mot. thanks

cats only came on cars from i think 1994 onwards, so yours wont have or need one mate

cheers for that what happens if i was to put a new engine in from a car after that date would it still need to have the cat or would i get away with it. sorry if it sounds daft just intrested

[gingergman]

to be honest i dont know, someone else should, but i would think it would need one to pass the emmissions test on the mot??

[Guest snel81]

Thanks was just intrested incase the engine ever goes but its sweet at the min so dont have to realy have to worry yet

[gingergman]

if you ever replace the engine then chances are for the age of your cab you will replace it with an engine of the same era, unless you do a mega engine conversion lol

Im pretty sure it goes by the age of the car not the engine in it so you can put a '96 2.0 zetec in for example and wont need a cat. Im only pretty sure not 100% though.

[Guest RelaxedDiver]

its by what ever is older, ie. the engine or the car chassis from what i remember

 

this site confirms it

thanks for that had a look an from what i can make out your wright it goes off what is oldist

Just to clear up any confussion

This only applies to vehicles of a certain year that had a cat fitted as standard equipment. So if you were to fitt a '97 16v engine you will still not need one.

The MOT contains different rules for different year cars, applicable to yours is a visual inspecton for smoke and a ges test to make sure the exhaust gas contains not more than 4.5% carbon monoxide.
