LS3 winterizing


Recommended Posts

Does anybody own an LS3? I'm trying to drain the block. Manual says: 

"Removing the knock sensor does NOT drain the block. Remove the caps from the brass hose fittings on both sides of the engine to drain water from the block."

There is no diagram. I don't know where to locate these brass hose fittings or caps. Anybody have experience with this engine?

There are two short hoses that look like the oil drain hose on either side of the engine. One will be near the alternator near the front of the engine. The other one will be closer to rear of the engine ... near the starter.

Good call! I found the port side, always thought it was oil drain. If there's one on starboard side it must require dismantling a lot of cooling hardware. I can't reach or even see behind it all.
