Where is the engine block drain(s) located on a 2001 dodge 5.2 liter? Am I looking for a plug or a petcock? Thanks.

You may need to remove the air dam, to gain access to the petcock/drain. Alternatively, you can just remove the lower radiator hose to drain the cooling system.

There should be two engine block drain plugs, one on each side of the engine. Be sure to disconnect the negative battery terminal first, since one plug is likely close to the starter motor--you don't want a giant spark.
