Anyone know where the coolant drain plugs are on a 2003 V6 engine block?

Johnny Mullet

There are none on the block that I am aware of.

So there is no way to drain the old coolant from the block when changing it?

We use a flush machine that gets all the coolant out.

To drain the block, get the engine hot and then pull the lower radiator hose.v This usually gets most of it out since it is still circulating. You could also leave it run with the drain plug out of the radiator and keep a hose running in the radiator.

Parts stores even have those flush kits that do a fine job.
