my coolant level has been dropping lately, even after i top it off. today i noticed some water or coolant puddle under the car. open the hood and see some leaking from a small round thing on the firewall on the passenger side. does anyone have any idea what that it? pic below
i got a misfire on #4. can someone tell me the orientation of the cylinders? on the driver's the plug wires are label 1, 3, and 5. But nothing on the coils on the passenger side.
