2000 QX4: drivers side..the throttle linkage..gasket

Customer Question

I have a 2000 QX4, there is a small coolant leak on the drivers side of the engine just below the air inlet port & the throttle linkage and above the oil dip stick. There appears to be a depression type valve with a gasket that looks like it is where the leak is. Is this a part that I can purchase and replace myself. What is this valve called?
