Rounded Coolant Flush Bolt

[PHATR32]

hey guys,

went to flush my coolant the other day and found the drain plug was rounded and couldnt be removed.

now you all know where the plug is and how hard it is to get to!

so what i done was undo to coolant line from the turbos (located just above the plug)

is this enough to flush the coolant? i even jacked it up high on one side so all the coolant runs out of the line?

any other ways of flushing the block??

There is probabley a little left in the block but not enough to worry about. If the drain bolt is that rounded that you can't remove it then the only other thing is to go to a local shop or dealer and have do a rad flush. That of course removes all the old coolant and replaces it with new.

Honestly though, I think what you did is just fine. If you go to the shop for anything I think that it should be for the worn drain bolt to be removed if you can't do it yourself.

ye i definetly cant remove the bolt, no space! dunno what the negineers were thinking.......

anyways, i put the garden hose in it and let it dribble till all the flush crap came out. then i let the whole system empty completly.

i also jacked it up one end to let the water run toward the plug.

should be ok i guess.

You've probably done the best you can. About the only other way would be to remove a welch plug.

I found out when I removed the plenum on my GTR recently that there's a second block drain plug on the driver's side of the block, between cylinders 3 and 4 - but it's even harder to get to

what shits me is i had the engine out last week and didnt even think about checking out the plug!!!!

haha

I found out accidentally that that line is pretty good for getting all the coolant out. Not too easy to get to though.
