First my engine could run hot but when I took it in they couldn't find a coolant leak but the coolant levels were still going down and needing to be replaced. Now there will randomly be pools of coolant on the ground under my car.
Also, sometimes my car decides not to start. Moreso, the last past week. If I play with the ignition and the gas it eventually starts up. Do I need a new starter? I got a jump start but it still wouldnt start so that leads me away from the battery.
The leak wasn't checked very well if coolant is on the ground you have a leak perform a pressure check tool that attaches to radiator cap Starter sounds like loose ignition switch. or a loose3 connection some where check wires to starter all the way back to battery would need some voltage info and year make and model to be more help

You have a coolant leak. The engine gets hot and pushes coolant out under pressure into the overflow tank.When it cools, the volume of coolant decreases, the pressure drops to the point that it becomes a vacuum. The vacuum pulls in air more easily than coolant. It's thinner. So, you keep losing coolant from the radiator which makes the engine run hotter, each time until it eventually overheats and does damage. You need to have the cooling system pressure tested. The leak will show up. Usually, it's a loose hose clamp or cracked radiator tank high up, which makes it had to see the coolant because it doesn't leak much and it boils off leaving little or no evidence. Fill the system completely before pressure testing. Remember, checking the overflow tank means nothing when checking coolant level. There's no short-cut to checking the coolant level, take the radiator cap off when cold to accurately check level. Read the safety precautions on the car but always check when the engine is cold. NEVER HOT.
1. If you need to jump start the car the battery is failing and you need to replace it. Other wise you may have an excessive power drain while the car is sitting which is running down the battery sufficiently so it will not run the starter motor.
2. If you have a low coolant warning light then you need to check the coolant level in the radiator when the engine has cooled and top it up using only the correct spec coolant for the car as specified by GM. Coolant level in the radiator needs to be checked very regularly in any event as does engine oil and power steering fluid level. If the coolant is low your engine will overheat and will likely cause very expensive engine damage many times what it will cost to fix the cause of the low coolant. You will have an external leak(such as a leaking radiator or leaking hose or failed radiator cap etc etc ) or an internal coolant leak that is causing the loss of coolant. Whatever the cause, and you need to have it investigated and repaired straight away if the cooling system continues to lose coolant.
Check the coolant level in the radiator with the vehicle cold, if you remove the radiator cap with it hot you could get burned badly. Just checking the catch bottle won't tell you if the radiator is full or not. If it is down, fill it with 50% solution of coolant and partly fill the plastic catch bottle. Then check it again after it has run and cooled again until the radiator level stays topped.
If the coolant level is down, you may have a leak; check for leaking coolant when it is warm and engine off. If it goes through lots of coolant and/or if it looks like brown mayonnaise in the radiator or oil filler, you may have a blown head gasket.
The engine being too hot could easily cause the hesitation but so could a bad head gasket.
So the level keeps dropping in the reservoir? If you have to keep adding coolant to the reservoir, the system is leaking or losing coolant somewhere. Have the system pressure tested to find the leak. Is the reservoir itself leaking? When the level gets low enough, first the reservoir will go dry, then the radiator level will start to drop.
Here's how the reservoir works: coolant is under pressure from the radiator cap seal. As coolant heats up from hot engine, it expands, and pressure forces the radiator cap seal up, coolant is forced into the reservoir-remember the hot mark on the reservoir? When car is shut off, coolant contracts, creating a vacuum in top of radiator. This vacuum works to suction coolant back from reservoir into the radiator, keeping the radiator topped up, and coolant should now be at the lower cold mark on the reservoir. It is a closed, sealed system. The only loss of coolant will be a very small amount of evaporation from the reservoir. If coolant level keeps dropping, there is a leak somewhere.
you need to replace thermostat and radiator cap.look under hood around engine compartment.look for a radiator cap near radiator,add 50/50 antifreeze and water to coolant system to bring up boiling point.pure water will cause engine run hotter because water evaporate away,remove radiator pour coolant in the radiator until coolant stop dropping in the radiator now some vechicle pour coolant in the coolant overflow jug,pour coolant until coolant level stop dropping and the coolant level stay at cold full mark.start engie let idle few minutes, watch coolant level in radiator if coolant start dropping add more coolant, when coolant level stop dropping put radiator cap back on let engine idle until both top radaitor hose and bottom coolant hose get warm turn off engine wait until it get cool then take a large rag slightly open radiator just a litle at a time to keep from getting scaled.once radiator remove add more coolant if low,put radiator cap back on start the engine let it idle watch the temp gauge if temperature gauge going hot zone stop engine wait until cool then add more coolant,keep doing this until engine stop overheating going into hot zone and coolant level stop dropping,make the coolant overflow jug coolant level stay at full cold mark, dont let jug run empty if so air will get in the coolant system causing engine to overheat.
YOUR TEMP GAGE WILL NOT REGISTER CORRECTLY WHEN THE COOLANT FALLS BELOW A CERTAIN LEVEL. WHEN IT IS SMOKING IT IS EXTREMELY HOT. IF YOU HAVE A COOLANT LEAK THAT BAD IT SHOULD BE NOTICEABLE EVEN WHEN IT IS NOT HOT. YOU NEED TO FIND THE SOURCE OF THE COOLANT LEAK. WATER PUMP, COOLANT HOSE, FREEZE PLUG, HEAD GASKET, RADIATOR CAP LEAK, OR RADIATOR, OR HEATER CORE. CHECK THE ABOVE AND YOU WILL FIND THE SOURCE OF THE LEAK.
ENGINE NOT GOING TO START IF GET TOO HOT FIRST THING I WOULD REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP THEN ADD COOLANT UNTIL COOLANT LEVEL CORRECT THATS WHEN THERMOSTAT OPEN UP AND TOP HOSE HOT.CHECK FOR LEAKING RADIATOR HOSES CHECK TOP RADIATOR HOSE CHECK BOTTOM RADIATOR HOSE.CHECK FOR LEAKS AROUND THE RADIATOR LOOK DOWN BELOW COOLANTS FANS CHECK FOR LEAKS AT RADIATOR CORES OR LEAKS AT THE RADIATOR PLASTIC SIDE CONTAINERS. CHECK FOR LEAKS AT WATER PUMP WEEP HOLE AND CHECK FOR LEAKS AT THE HEATER HOSES AROUND ENGINE BLOCK TO THE HEATER CORE HOSES. THERE IS A REASON CAR OVERHEAT.IF CAR OVERHEAT WHILE DRIVING YOU HAVE FAULTY THERMOSTAT OR LEAKING OUT COOLANT OR BLOWN HEAD GASKET.IF ENGINE OVER HEAT WHILE SITTING DURING A LONG IDLING PERIOD.YOU COULD HAVE FAULTY COOLANT TEMPERATURE SENSOR OR FAULTY COOLING FAN FUSE OR RELAY.HOT WIRE COOLANT TO SEE IF IT RUNS IF NO REPLACE FAN MOTOR. IF YES FAN MOTOR COULD HAVE FAULTY WIRE OR PCM FAILURE. CHECK ENGINE CRANKCASE IF OIL LOOKS LIKE MILK SHAKE ENGINE HEAD GASKET LEAKING.
That's probably coming out of your coolant return bottle. With rad cap off & engine cool, look at your level in the rad, if necessary top it up to an inch or so from top. Start engine, turn heater(not defrost) on and let it run until up to normal operating temperature. Keep an eye on temperature gauge & rad level. When it's at normal, watch for good flow going through rad when thermostat opens. after flow slows down,(thermostat closes) top it up if needed. If you watch 2 or 3 times for flow, and gauge doesn't go over normal, then put cap back on, then fill bottle only to mark for warm or hot engine, with coolant. If gauge goes up over normal from there, replace thermostat, and I'd get a new rad cap too. If that has electric cooling fan, make sure it comes on shortly after you see thermostat open & coolant flowing through rad.
Having coolant leaking problems, everytime the car runs it runs hot, coolant filled, when car is then turned off coolant leaks out on drivers side underneath radiator. Hissing sound also on drivers side when running hot.
