Replacing Water (Coolant) Guide Housing '05 Boxster S- Help!
in 987-1 Series (Boxster, Boxster S)
Posted
I wanted to reply to this thread since I also had to replace my coolant pipe assembly (or "water guide housing"), and there doesn't seem to be any mention of this repair anywhere else online. I'm guessing not many people have issues with this part, so we're in the unlucky few.
My '05 Boxster 2.7 developed a coolant leak roughly a week after I completed a preventative water pump replacement. I noticed the leak under the front of the engine and assumed that the new pump was the culprit. Turns out the coolant pipe assembly was seeping from the top, due to a bad seal. I tried draining the cooling system and using JB Weld at the source of the leak (which was hard to pinpoint, since it was hidden directly underneath a pulley). This didn't hold, so I also took upon the task of removing this part.
Here are a couple of things I learned:
Originally, I was only going to replace the top and bottom seals on this piece, but after going through the work of removing it, I'm going to replace the entire part ( #987-106-508-04). This is not a job I ever want to revisit in the future.
