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.

i have replaced my oem oil cooler with a new better one (handmade) , i want to ask if you know at how many rpms the valve opens? thank you

and a second question that i have is if anyone know how much pressure from 0 oil psi or bar shows the climax on the oem gauge (ae92)
