If you are talking about the Toyota factory oil cooler with a return hose
into the oil pan, then not important.

The factory cooler is a by-pass type, and oil is only sent to the cooler
when the rpm's (and oil pressure) are high. At lower rpm's the spring-
loaded bypass valve is closed, and no oil is sent to the cooler. So for
normal around town driving the cooler is just extra weight.

Before I rebuilt my engine I was running a corolla sump and obviously couldn't connect up my aw11 oil cooler arrangement and never had any issues. Have since bought an aw11 sump with the oulet.
