3.0 abnormal coolant leak

Featured Replies

Just noticed/discovered coolant collecting on the right rear side of the engine.  Fairly sufficient leak.  Dripping down on the motor mount.  At a lose at what is the source.  Can't see any coolant hoses on that side of the engine. Is there one for the throttle body?  Is there a temp sensor in the area?

Discovered a coolant line that side of the engine and decide to just replace everything over there since the intake manifold has to be pulled.  What is a good online Subaru dealer?  

Yep, there's a steel line under the intake manifold, with a little rubber hose up to the throttle body, that's likely your culprit. Can be capped off or bypassed.

I love Toyotapartsdeal.com, and they have a Subaru counterpart (www.subarupartsdeal.com)

EDIT: FYI, when I google SubaruPartsDeal, it appears that they are owned by Genuine Parts Giant, Inc., which supplies parts for all types of cars.

Thanks for the links.  Decided to bit the bullet and went and ordered all new hoses.  Figured why not since the intake needs pulled.

You nailed it.  Took a closer look this morning with the "air tube" removed and noticed one of the hose clamps was installed wrong.  My fault when I pulled the engine 2 years ago to correct another one of my screw ups.  Took the wife out for dinner and put 60 miles on the engine and no leak.

Whoops. Tried to just add [url ] tags....fixed now.

 

Yes, it's the same company. I haven't bought Subaru parts there, but I've bought others. I use their website all the time, as it will actually show you if a part is discontinued.

Glad it was an easy fix!
