Rb25Det Engine Block Water Fittings

[copycutter]

At the end of last week I noticed my car was leaking coolant. After having a bit of a closer look, I noticed it was the water line that goes vertically down from the coolant bleeder, and into the engine block.

I removed the line and noticed that the metal nipple that the coolant hose joins onto to has corroded, meaning that the end of the metal nipple is now jagged and straight instead of that mushroom head shape it normally has to stop the hose coming off and I presume also stop it leaking (makes a tight seal against the rubber hose).

Anyway it took me nearly a whole day to take off that hose and a larger one near it to determine which was the cause of the leak, and then I replaced the standard clamp that you pinch to open with pliers, with a worm drive hose clamp. It's very tight working under the inlet manifold so again, it took me ages, and lost lots of skin from the hands. Yay.

I eventually got around to topping up the coolant again and noticed it was still leaking, even though I had tightened up the clamp as much as possible since it was free spinning if I try to tighten further.

What does everyone do in this situation? The metal nipple is solidly connected to the engine. If it were to be replaced I'd imagine you'd have to cut it off and weld on another, which would require the inlet manifold to be removed.

Surely this level of repair isn't what's needed in this situation. Please help. My car is off the road because of a dumb water leak and it's annoying me.

Maybe the hose is just to old and hard and needs replacing.

If you dont want to pull the hose out etc then you can dry off the nipple and the inside of the hose (easier then it sounds, contact cleaner might work) and smear some bluemaxx or threebond etc on the nipple and then stick the hose on and clamp it. Let it dry then top up with coolant

It may or may not work. Hard to tell without looking at it
