Default Coolant Leak & I noticed something else.

My low coolant light has been coming on frequently. First I checked the overflow - which was completely empy. So I filled that and checked the radiator. That was fine. I drove for a little while and the light came back on. I popped the hood, and noticed that right under the SC snout there was a small puddle of coolant. I'm guessing that the fitting there went bad, since it'* plastic. Okay, that'* problem #1. While looking at that leaky fitting, I noticed some oil seepage coming from the intake gasket area. :( Will a leaky intake gasket cause rough idling and horrible gas mileage? And is this an expensive repair?

Thanks guys!

Well i have no doubt that the fitting under your supercharger is broken. I've seen many MANY of these in my shop some in with coolant leaks, and it'* because that fitting snapped completely off. You have to take your alternator off to fix this, and really the most difficult part of it is getting the broken part out of the intake. I usually use a drill bit, i can't recall the tightest fit at the moment, but use a bit that'* for drilling metal. These have the super sharp edges and will pull it out. Tap the drill bit into the hole where the fitting was till it won't go more, then twist SLOWLY counter-clockwise. This should get it out. When you get a new fitting get a BRASS one. These are the best direct replacements. I know many other guys on here will be with me on that. Also use non-hardening sealent on the threads. As far as your oily intake mating surface, this COULD have some small effect on mileage/power, but if you're not getting any knocks and your boost holds up under load then you're probably OK.

I didn't have to take off the alternator to get to the coolant bypass fitting. Yes, DEFINITELY get a metal one. I used a hacksaw blade to saw off the plastic fitting that had broken inside.
