It's help the dummy time. Would like to change the antifreze in my 2004
Frontier but can't find radiator drain plug. Can someone please tell me
where it is located and since it is not a wing nut type of protrusion,
what I am looking for? Thanks for any help

Might it not be on the lowest part of the block, allowing you to drain
the whole achievement?

In the 1950s, some trucks had two: one on the rad and another on the
block.

though. Remove a rubber flap between the bottom of the radiator and the
frame. It is held in place with plastic trim pops. The actual drain is
dead center of the radiator and is a phillips head screw out plastic
plug. Thought would post this in case anyone else is looking for it.

Just remove the lower radiator hose. This won't drain everything from
the block, but the engine is unlikely to have a block drain and
removing the hose is as effective as a radiator drain plug.

Ed,

Nissan engines have both a radiator drain plug and engine block drains.
This is not a Ford.

I know my 06 Frontier had a radiator drain, but you can't beat
removing the lower radiator hose for quickly draining the system. I
never looked for a block drain plug on the Frontier, but with all the
stuff under the hood and underneath (4WD) it was almost impossible to
see anything on the sides of the engine (V6).

All the Fords I have owned had a radiator drain plug. I have no idea
about a block drain. I never looked for one. My usual practice when
changing antifreeze is to drain the system, then flush the system with
one of those Prestone kits, then drain the system again and refill wih
coolant. I don't use distilled water, so I am not perfect. However,
years ago my father told me that the water from our farm wells was
"good" for radiators. Not sure why, but it seems to be true. I've
never actually had a radiator problem related to corrosion, and that
includes a couple of tractors that were 40 years old.

What's the hurry? If you have a radiator drain, use it. The only thing you
accomplish by pulling the lower hose is the possibility of damaging the
nipple on the radiator, the hose or the non-reusable OEM clamp. Why take
the risk?

I'll grant you Nissan block drains are less then obvious & the diagrams in
the FSMs to find them are all but useless. The only reasonably usable ones
I've encountered are on Hondas (visible, accessible & not torqued to
ridiculous, useless levels). The only way you're going to see any of them
is up from the bottom. But, as you say, hardly anybody bothers with block
drains. A flush is much easier.

The only cars I've encountered that did not have radiator drains are a
couple of Lincolns & an Isuzu.

OK, now we're being anal retentive. The radiator has a drain plug & the
engine has one or more bock drains.
