Coolant Leak

Alrighty, I found the cause of the coolant leak. I had the car up on the ramps, looking everywhere underneath, and I figured I'd have to take it somewhere. I couldn't figure out where it was coming from.

Then...! I had the ingenious idea to actually start the car. Sure enough, I found the drip, up on top, from the hose coming out of the throttle body down behind the engine.



Can you see it back there? It's on top of the engine, but underneath the hood cover where the windshield wipers are. To get to it is going to be fun, but nothing I haven't done before. I talked to Aaron for a while about it, and we determined that it was one we'd replaced when we installed the supercharger.

Here's a better look once I got the hood cover thing off.



And once I could tell that it was the hose actually, and not like a clamp or something not functioning, off I went to Advance to get something comparable to replace it.

Aaron had found the supercharger install book that I'd emailed him in 07 in his Gmail archive. I love Gmail. This let me know that it was a 5/16" hose. I bought 2 feet of it, just because I wanted to be sure I had enough. It was only $1.39/ft. I couldn't complain, so I wasn't THAT wasteful.

I noticed on the way home coolant was coming up and spraying on the windshield a little. Here's what I was greeted with when I opened the hood.



After releasing the pressure it stopped spraying. I wanted pictures though. After that, it was pretty easy to just replace the hose & clamp it on. Nothing to it.

Everything appears to be working great. Guess we'll find out soon enough.

Last problem is that whirring noise. I only hear it above 20MPH and even with the engine shut off (yeah, I shut off the engine driving down the road). Not sure what that is yet... maybe brakes? I just did the rears... perhaps I screwed something up? Or perhaps it's the fronts? It does sound like it's the front.
