02 Malibu Coolant Flush

[I_Like_Cars]

I'm having trouble locating the plug to drain the coolant in my wife's '02 Malibu. It has build up around the pressure cap so I definately need to change the coolant. Can someone fill me in on where that plug is? Thanks.

I assume 3100 v6? How many miles?

I remove the lower hose to drain radiator.
There are two drain plugs on the block.. one between starter and oil filter, one near crank sensor.

My bad, yeah 3100cc V6. I found the one on the lower right hand side on the radiator itself but I couldn't locate the block drains. But your info does help. Thanks a lot Mark.

Change your coolant bottle cap if it's the original one.

yeah, I think I will do that

If you change the puke tank cap, make sure you get an OE replacement with the same pressure rating.

If there's any buildup inside the tank, it's a pretty good idea to remove it from the vehicle and soak it real good, then flush the hell out of it.
