Speaking of hose leaks and clamps, notice the area pointed out by the arrow in the photo below. If the cap is leaking, why would there be coolant residue on that small pipe in that particular area? Is that pipe ever substantially pressurized during normal operation?
Do you think that Nissan's small and large OEM hose clamps shown in this photo clamp down / seal those hoses against the pipes as well as say traditional stainless steel hose clamps that are tightened with a screw?
I ask because I'm wondering if I should save some time, travel and trouble and replace those two OEM clamps with those I just mentioned, because the more I think about it, the more I think that it is not the cap that is leaking.
Thanks.
