shaunzo101 Posted July 4, 2011 Share Posted July 4, 2011 Hi there, I have water leaking out of a 14 mm bolt head out the side of the block on my rb25det, its right below the water line for the turbo. What is this for? And why would it be leaking? Link to comment https://www.sau.com.au/forums/topic/369969-whats-that-bolt-for-near-the-turbo-water-line/ Share on other sites More sharing options...
SargeRX8 Posted July 4, 2011 Share Posted July 4, 2011 Isn't that the water drain bolt for the block? Tighten it up, may have rattled or vibrated loose. Could even be water from your turbo line running down to the bolt...

JonnoHR31 Posted July 4, 2011 Share Posted July 4, 2011 iirc its just a bung, pull it out and clean the threads, put some thread tape on it and put it back in nice and tight.

shaunzo101 Posted July 4, 2011 Author Share Posted July 4, 2011 it's definitely the bolt below the water line for turbo. I will go with the idea of putting thread tape around it. I'll give that a go tomorrow and see how that turns out.

shaunzo101 Posted July 5, 2011 Author Share Posted July 5, 2011 success, went down to the local fasteners shop and he picked one off the shelf straight away, $2.55. Put that one in with some thread tape done it up real tight with help of a breaker bar, retightened the water line to turbo while i was at it and no leaks. Hopefully it stays that way.

shaunzo101 Posted July 5, 2011 Author Share Posted July 5, 2011 by the way the guy at the shop said straight away its a water drain plug.

SargeRX8 Posted July 5, 2011 Share Posted July 5, 2011 Did you fit a copper washer between it or just thread tape it? The thread tape is normally enough, I just use copper washers on all bolts which seal for the extra bit of protection.

blk94r33 Posted July 5, 2011 Share Posted July 5, 2011 by the way the guy at the shop said straight away its a water drain plug. Yep. Says in the workshop manual the bung is used to drain the coolant completely, rather than just form the radiator, when changing the coolant.

Only thread tape because the bolt is tapered, so the bolt is wider towards the head of the bolt if that makes sense.

Adriano Posted July 6, 2011 Share Posted July 6, 2011 Only thread tape because the bolt is tapered, so the bolt is wider towards the head of the bolt if that makes sense. For that reason you shouldnt tighten the bolt with a breaker bar, as it can crack the block, snug is good enough Link to comment https://www.sau.com.au/forums/topic/369969-whats-that-bolt-for-near-the-turbo-water-line/#findComment-5899696 Share on other sites More sharing options...
