Another coolant line? You gotta be kiddin me...

[skillzilla]

This one was behind the engine, connects to the underside of the throttle body. Lets just say I HOPE its the last one, I shoulda just done them all when the engine was out.

If I'm not mistaken that is the line that prevents your throttle body to be stuck frozen. So yes that would be another coolant line.

What is wrong with it? Leaking?

It blew up right where it connects to the hardline at the back of the engine, and got my car stuck for a day in the work parking lot. Thats the 4th time this has happened to me, am I cursed or what??

You should change all your hoses and clamps. Flush your system really good also. You might have a clog and it increases your system pressure. Don't really know but just a thought.

I've had two hoses split on my RB25. The big diameter hose at the back of the engine under the plenum and the turbo water return hose.

A friend of mine whos a Nissan technician said its a common problem with Nissan engines that have been stored and allowed to dry out inside. The hoses seem to rot from the inside.

If I did another RB transplant I'd change the hoses as a matter of course. :rolleyes
