hey all...
I needed to drain my coolant on my 2010 mazda 3 I loosened the Phillips
plastic screw found on the Left bottom drivers side and It did loosen however
I couldn't get it out of the bottom rad it just would not come strait out for it
to drain the Radiator.

wich Leads me to think this is a poor design flaw from mazda.? after 20 minutes
of trying I tightened up the screw and said heck with this.!!
instead I went over to the right side and located the Lower rad hose
and loosening the clamp managed to pull the hose with ease from the bottom
rad drained the coolant

 

I right this meaning no disrespect to you at all.

Not a poor design, just someone without experience working on a unfamiliar item of their car.

 

I have drained rads on other cars without issue but this one
had me disappointed I still think its a lousy design I like the
car just not there drain valve on my 2010 mazda3.
