Car over heating, fan won't come on. problem didn't start till alternator was installed

if fan belt broke
that means alternator not charging battery so need to jump start the car as battery is flat and will not be charged till fan belt is on.

Alternators can sometimes whine when start up on a cold morning, they run on full load till they get the battery back up to full charge. When the whining stops, switch on electrical equipment (Headlights, fan full boost, heated rear window) if the whining starts again its the alternator.

Your battery is discharging because you have a circuit drawing power when ignition is off. You have to identify the line by hooking up an ammeter to the battery and with the ignition switch off, start removing fuses till the draw goes down. Once you locate the offending circuit, you need to check all of the wiring and items on that load.

I have a 1985 Camaro and if the switch for the fan is off then it overheats. There is a fan that can be installed. My switch is on the left of my steering wheel. Tune up is always good. Have your alternator checked, if it's old can be a problem maybe. New spark plugs can't go wrong. Good Luck!!!

Most engines don't fair well under extreme heat. It's apparent you might have some electrical issue's. Your rpm's or mph arm going up and down could be faulty speed sensor would cause arm problem. I think you may have more than one problem, the car shutting off is due to engine over-heating. Check cooling system-thermostat, water pump, radiator, engine fans and coolant temp sensor and fan relay's. It could be as simple as blown radiator hose.

You won't get heat right away. The heat has to have time to reach the heater core. That's where you get the heat for the passenger compartment. But if the fan isn't turning off, then I would have it checked for an electrical problem.

{: ) You didn't mention the model of your vehicle. Anyway, we can try some cooling system basics.
You can begin checking with the things that keep the engine cool.
1. The coolant. Are you using plain H2O? Check the coolant level and also look for signs of coolant leaks.
2. The radiator. Check for obstructions at the radiator area like plastics and debris. Foreign materials could have accumulated on the radiator fins. Clean if necessary.
3. Cooling fans. Check for damages or cracks. Is it operating at expected speeds when it should be? For example, at 106deg it works on low speed, at 110deg it should spin high speed. If it stays on low speed all time or none at all, check the fan relays and fuses.
4. Water pump. Is it noisy? Have you checked the belt? It may be old and cracked, better replace it. If a thermostat is stuck, coolant won't circulate and engine will heat up fast to undesirable levels.

How about the other things that add more heat to the engine?
1. Engine pulleys getting stuck. A/C, water pump, steering pump, alternator, idler and tensioner pulleys.
2. A/C system high pressures on the condenser.
3. Oil level and pressure low
4. Poor engine emissions performance. Engine timing, tune-up, clogged exhaust pipes
5. Stuck brakes or bearings
6. High ambient temperatures
7. Poor wheel alignment, low tire pressures

I hope I didn't miss out on any other more important things to include. Wish you goodluck.

The starter or it's solenoid

The new battery & alternator didn't
but the problem in there

Check for spark and fuel. When you turn the key on you should hear the fuel pump in the tank for a few seconds till the pressure builds up. When you crank the engine there should be spark at the plugs.

TEST YOUR ALTERNATOR AND HAVE THE BATTERY CHECKED IF THEY ARE OK
YOU MAY HAVE ELECTRICAL SHORT
