I'd like to drain the coolant on my '98 Isuzu Rodeo, 3.2L V6 (4wd). I
found the drain on the bottom of the radiator. The Haynes manual says
there should be 2 more drains, 1 on each side of the engine block. I
find these 2 drains. Can someone please try to help me find them? What
do they look like? What tool is needed to remove them? Is there a photo
anywhere of them? As much detail as possible would help. (When
locations, please use "left" side as "drivers" side).
They are probably hidden by the exhaust manifolds... and useless.
They are on my 94 Rodeo with 3.2l SOHC. You have to flush it three or
four times (empty radiator... fill with plain water... run to open
thermostat... repeat) to get all the old coolant out. Splicing a tee
fitting that connects to a garden hose into a heater hose helps a lot
with this. Prestone sells a kit with the tee fitting and a splash
deflector that is perfect for this.
I catch the first drains in a big pan and let it evaporate, which it
readily does. The latter drains are so dilute it just doesn't matter
It's sweet tasting and poisonous... dogs will lap it up if you leave
it undiluted in puddles. That's where the hazard is... because
otherwise it evaporates.
Back in Texas, many auto shops and auto parts stores would take in
used oil and coolant, adding it to theirs, and sell it to recyclers.
I don't know what they do here in Pennsylvania... guess I'll have to
