coolant leak?

Asked by Mar 03, 2015 at 12:03 AM about the 1999 Pontiac Grand Am 4 Dr SE Sedan

Question type: Maintenance & Repair

I have recently replaced the water pump,
thermostat, resovoir bottle and coolant on
my 99 grand am. My problem is that im
getting the heat on and off and losing
coolant. Today i noticed coolant spitting
out of the left side of my exhaust manifold.
Theres no bolt there holding that side which
i found weird anyways. So mu question is,
is it a bad head gasket or manifold gasket.
It also sputters while idle and also i can
hear a hissing noise coming from around
the carb. This all started about two weeks
ago and about a week ago i was driving to
work and the car overheated that is when i
started replacing everything. Also i checked
the sparkplug above the area where its
leaking and the plug is now at .058
thousandths or something like that and it
was black. please help!!
