There can be many different causes for coolant leaks. What makes you think you have a coolant leak? If you are noticing a puddle of coolant underneath the car, then chances are its related to your radiator or the hoses that connect to it. It could also be your water pump and its hoses. If your car has been over heating and there is no puddle on the ground, then you may have a bigger problem on your hands - you may have a cracked head. There are so many factors involved when it comes to a 'simple' coolant leak. My advice, take it to a reputable auto mechanic and let him diagnose it for you. Good luck.
It must. I am having my '94 Camaro's timing gasket changed for just that reason.

a leak in a head gasket could cause coolant to go into only one cylinder.
A low coolant level could cause the temp gauge not to read correctly. A faulty temp gauge sending unit could also be the cause. The coolant leak, you would have to find the source of the leak to determine the cause.
The coolant leak is pretty cut and dry - you have a leak somewhere. The lukewarm heat (assuming you're referring to the car's heater) could be for a number of reasons. Insufficient coolant could be one of those. Your coolant could be burnt out. It could be a problem with one of your heater hoses. You could have a worn out heater core.
Could be an A/C coolant leak.
The leak could come from: hoses, punctured radiator, split gasket...you can put tracer dye in the coolant and search for the leak with a black light after you clean the engine.

Probably a coolant leak.
you have to find where the leak is first.
If you do not visibly see a coolant leak, have the cooling system pressure tested. If the leak is not obvious it could be internal.
