    ok,in a cadilac,you should not bypass any coolers,unless you live where it is 30 degrees all the time,cadis need that extra little bit of cooling,you can replace the cooler,you can buy a generic one for about 30 bucks,they all are about the same,just google "external oil cooler",and find one for your car.

How can I bypass the OEM internal engine oil cooler with an external aftermarket oil cooler on a 2001 Saturn L300 3.0LV6?

Can you pipe the hot oil out to the after-market cooler, let it work, and pipe the cooled oil back in? You're not giving the internal cooler any "work" to do, but who cares, since the goal is to cool the oil.

Why does my 91 ranger dies when put into reverse?

bypass where the automatic transmission lines go into the radiator, many fords will have a plugged up trans cooler that will restrict flow and stall the motor when shifting into reverse. if you find the bypass fixes the problem then install an external trans cooler.

Celica 1.8SR

Does your car have a 5SFE engine? Is the oil cooler right behind the oil filter? There is a rubber gasket there that has been known to fail. I have never seen the cooler "fail"; it is always the gasket. Don't bypass it, it is there for a reason, and is NOT "overkill".
