Corsa engine identification

[dwdwdw]

hello all

I am trying to buy a timing belt for a 1997 R, corsa breeze, petrol, 1389cc, engine
number is 02FR5973, chassis no is 78V4290927, VIN is WOL000078V4290927. But cant get past the what engine is it mate, I have looked where the haynes manual says it should be stamped but it only says GM. any idea where the engine type is stamped or can anyone tell me from the above info what the engine is. It has vauxhall written on the rocker cover not ecotech

Thanks for your time all the best Dave

Have you called your Vauxhall dealer, they should know straight away?
