i10 vs Atos engine
 

I have an i10 2013 1.1, my engine overheated and bought a replacement engine from an authorised reseller/importer. My mechanic says that the replacement engine is from an Atos and won't work, the resellers say it's the one and the same engine with the only difference being the manifold . I need some advice on this before spending more money.

much appreciated .
