Hi all I was wondering if anyone could help me with this I've found a Sierra 1.8 diesel on a 92k reg and was wondering what diff it would have in as when looking on Sierra diff website I can only find a2.3 diesel
Any help please

The ratio is stamped on an aluminium tag bolted to the rear cover plate of the diff.

This guy has a lot of info

1.8T looks like a 3.38

Ok will look at that info

Thanks again

The diff code MAY be stamped on the vin plate as well.. I'll hazard a guess it has a good ratio diff in it...
