man you are loosing you gear box fluid ( valvulien oil ) go to gas station fill the gearbox check it if its dripping

here is an honest answer, this is not a job for someone who is not 'mechanically inclined'. It is very difficult to do, very difficult to reach and it has a lot of components that will need to be disassembled to even get it out. best thing to do is bypass it (it's warmer weather now) by taking the hoses off the core as they enter the firewall, and joining them with some kind of pipe/adapter. You will not have heat (for now) and you can figure out a way to get it replaced in the next 6 months and still drive it without antifreeze on your passenger side floor. I have been working on cars for over 25 years, some of the most brutal jobs I have ever done were heater cores, trust me.

no the day running bulbs go out during night driving

you need to have the engine coolant switch checked,since the computer relies solely on sensors,the ect tells the computer how cold or hot it is so the computer will make it a rich or lean mixture to start the engine,if it tells the computer that it is 75 degrees the computer will lean the mixture like starting a car in the winter without a choke.

There is a possibility that your temperature sending unit for the computer is not working correctly. ( not the sending unit for the gage, there are two). If the computer never knows that the engine warms up, it will keep "choking" and over fueling. Thus, the black spark plugs.

I own a 93 GMC and I have had this happen a few times, First its a chevy they are cold blooded take a bit to warm up and get heat. That and im sure the oil had not warmed up and gotten up to the top end. Let it warm up then try it out.

DIFFICULT STARTING CAR IN COLD.WOULD BE A THERMO - TIME SWITCH.THE THERMO TIME SWITCH CONTROLS THE AMOUNT OF TIME THE COLD START VALVE IS HELD OPEN BY MEASURING THE COOLANT TEMPERATURE AND UTILIZING A TIME FUNCTION TO PREVENT AN OVER RICH CONDITION.THIS COULD BE MOST OF YOUR PROBLEM.BUT SCAN IT TO SEE WHAT PCM CODE YOU ARE GETTING.

Have you check the plugs, cables, cap/rotor ?

One thing you can try since it starts good in warm weather, is to ,on a cold morning, take a hair dryer and warm up the suspect part to warm weather condition. Then try and start the car. If it start ok you have probably found the weak part.
