Coolant Leak 92 300CE
I have a coolant leak on the north side of the coolant reservoir (white plastic box). The leak is coming out from in between the hole and a black plug that plugs the hole. The black plug has a wire coming out of it. Would appreciate it very much for answers to the following questions:
1. How do I fix it? Is this a simple fix?
2. What part (pls. include part no. if known) needs replacement?
3. My guess is either change the plastic coolant reservoir or change the black plug but what about the wire that connects to it...what is the name of this black plug?
4. Finally, would a bad engine mount cause engine hiccups and/or hesitation?
Thanks for your help.
