EGR blanking / blocking - what is the real deal?

[Big-D]

You can check if the monty has one. It looks like a small intercooler. The ranger has one.

Sir Djerms,

Are you referring to the EGR cooler?
Other Montero owners are saying meron, frankly hindi ko alam kung asan banda sa engine bay, I guess malapit sa turbo so it has to be sa harap ng passenger side.... malamang ganun din sa old Fortuner ko.

Kung meron nga, do these coolers need maintenance too?
