Banjo bolts on the side of the block - what are they for ?

[3barboost]

Hi help !

I got a 1uzfe from my jap engine man and it has these banjo bolts (presumably for water) on either side of the block just above the sump line - what are they for ? and must they be connected ? looped ? can I just block them off ?

thats the the coolant drain dood.

When you want to drain coolant from the block, you attach a hose to the metal pipe on the side and loosen the bolt until the coolant comes out. (you dont need to take the bolt out).

Just make sure the bolt is done up. You can leave it as is mate.

theres one on each side - the one looks really rusty the other nice and normal - they both drains ? I would never have guessed in a million years they were drains ! I was thinking of feeds to something - never seen the engine installed so am somewhat lost on some things - thanks for the advice
