I can see traces of antifreeze in that area where it is hissing but it is hard to see. What could be leaking in that area?
Could be leaking at the top radiator hose going to thermostat, that is a hard spot to see leak remove the air filter and air filter housing look below throttle body you see thermostat housing, check for leaks around thermostat housing gasket and check for leak at the top radiator hose going to radiator and thermostat.if all is good check all radiator hoses for leaks check small coolant lines going to throttle body for leaks and check make sure bleeder screw on thermostat housing not loose it will leak also check around radiator and water pump heater bypass metal lines for leaks.

No heat is probably a result of low coolant, which basically starves heater core when necessary to feed rest of engine when coolant too low, or an airlock. I really think it's time you took it to a rad shop or similar & had a pressure test done on system & a proper diagnosis. Delaying it will only cost you more, like a whole new engine.

replace the power brake booster. there is a rubber boot inside the booster that has a hole , and when you depress the brake it opens the hole.

IT IS MOST LIKELY THE INTAKE GASKET LEAKING THIS IS A COMMON PLACE ON OLDER MODELS.
SOURCE: My 1999 chevy tahoe is leaking antifreeze. I
it could but- check passenger side front where heater core line go into manifold right behind alternator the hose line is connected by a press clip into an alloy fitting this fitting gets eaten away by anti freeze and hose angle pulls back on fitting the part is $18 at dealer and is screwed into manifold use caution if ur r going to replace at very edge of aluminum manifold---and check ur water pump bolts the 2 longer ones should have a lock sealant on them they bolt in thru a water jacket
SOURCE: Anti-freeze leaking from either the freeze plug or
Without knowing what year or engine size is, I/m just guessing??????? But the 3.1L engines are FAMOUS for intake maniflod gaskets leaking. Look where the intake bolts to the heads. A freeze plug is in the block. Freeze plugs dont leak unless you have been running pure water or weak/cheap anti-freeze. They will rust out from behind and its BIG BUCKS to replace them all.
