So a few days ago I pulled out the coolant reservoir to put in my new HID's. Everything was great until yesterday, I get the low coolant symbol pop up on my dash. I get home and am shocked to see the entire contents of the coolant reservoir had completely spilled out. I filled it back up and couldn't find a leak but then I turned the car on and I observed a steady drip from around the coolant level sensor. That sensor was a pain to get out to move the tank to get to the headlights and I haven't had the time to pull the tank out to get a good look at it but could the tank have cracked near the sensor when I was pulling it out? Where can I get a new tank and how much does it cost?
