The correct size oil cooler (front-mounted) for a 1.5 to 2-litre engine is 13 rows high x something close to 235 mm. (9.25") wide. A good hose-bore to use is 12mm. (1/2").
An excellent, world-class supplier of oil coolers, sandwich plates, accessories & model-specific kits, can be found by typing MOCAL into Google.
I hope this is helpful, as one of these has reduced my cruising,in-sump (pan) oil temperature, from 125C. to 80C..
Nick.
