Oil cooler sizing

[gaz g40]

Before i used to use a 13 row oil cooler and was wondering if i could get away with a 10 row instead my cars still charged with the usual 1341 and big valve head any opinions?

I think a 13 row is thought to be fairly ideal a G40.
Do you have an oil temp. gauge to monitor your current oil temperature?

[gaz g40]

No but im going to fit one into the car this time around though just to see.

a 10 row should do you if placed in good air flow, 13 is ideal but it might just do you on a 1.3

Are you planning on doing any track days?

Nope bot planning in any track days thats why i wondered if a ten row would do fine. The 13 was fine dont get me wrong just a big ugly thing thats all but stoppe that oil light beeping that is for sure!
