 Block coolant line
If you happen to notice the block coolant line under the intake leaking, it would be highly recommended that you change it.
These things have been known to rot and wear over time and temp. I've seen picture after picture of these things falling apart, flange deterioration, nipple deterioration. I had this happen to me, everytime the engine temp rose above normal, the hose would blow off of it.
It's worth the money (expensive plastic) and effort to unbolt your intake and pull it back enough to replace it.
While you're at it, you might consider replacing the one on the back of the cylinder head. Both are a little hard to get to, especially on a Z3 however; well worth your time and piece of mind. |
