Omega B – X30XE – Is the installation of an additional oil cooler from Cadillac Catera useful..?

At the current increasing local temperatures and the already existing heat problem due to restricted space conditions in the engine compartment of the stronger Omega B models, I wonder if it makes sense to use the oil coolers installed in the warmer areas of the USA in the Cadillac Catera also in this country. I think it won’t hurt. What do you think about it? Dietmar
