if fan is belt driven you have a worn fan clutch check where shaft enters clutch if there is any leaks or clumps of road grime sticking to fan clutch its lost its internal oil supply causing slippage some clutches will slip when engine is cold and automatically spin faster as temp rises this is called a thermostatically controlled fan clutch also w/engine off grab fan firmly and check for any play between blade and shaft replace as needed

How do you check your altinator?
take it to autozone they test for free failing that try this pre-90's car? unplug the battery while running if the engine dies it's probably a bad alternator (or the alternator is too small for the electrical load of the vehicle) after 90's? hook a multimeter to the battery while engine is running the voltage should be between 13.5 and 15.5 volts depending on engine rpm
Why does your heater blow warm air then cold air?
You may have air trapped in the cooling system. Remove rad cap, start engine and let it run for 30 minutes with the cap off while you add coolant as needed. That should do it unless you have a cooling system leak.
Flashing battery symbol while driving?
Could be that the alternator is not charging the battery properly Check with a voltmeter A fully charged battery should read around 12.8 without engine running With engine running voltage should read around 13.8-14.2 The most likely cause is a broken alternator drive belt
Can a loose positive battery cable prevent the alternator from charging the batter and can it cause a battery drain while the engine is not running?
Yes, a loose battery cable will prevent the alternator from charging the battery. The drain on the battery is not caused by the engine not running unless an accessory is left on. Most likely, the drain is caused by accessories (radio, lights, etc) while the engine is running due to the battery not receiving its charge from the alternator and then not having enough charge left to start the engine.
What would make a car die when stopping after cleaning the battery connections?
I hope you did not remove a battery post while the engine was running (don't do it)? If so, it may cause damage to your alternator, and it will short out your ignition in the engine (engine stops). If there is no damage, it should work after reconnecting the battery posts. If you didn't do the above situation, I would check for a loose connection on the terminal or a corroded/broken cable.

Why does your cooling fan come on when car is just sitting?
While your car is running the engine is heating up. While your driving you have air being forced over the radiator cooling it off. When you are sitting still you don't have that air so your engine is heating up even more so the cooling fan comes on to help cool you engine off. Via cooling the radiator.
Why does a car run at a normal temperature while running but gets hot while idling?
Cooling fan may not be working as it should. If it is not coming on either the fan is defective, fuse is blown, or the thermal sensor is bad. If it is running and the engine is still overheating the radiator may be partially clogged.

Oil sputter while engine is running and oil cap open?
Oil sputter is going to be a normal thing if the oil cap is not on while the engine is running. The engine should never be run with the oil cap open. The engine actually has less compression when the oil cap is open, and this could hurt the engine.

Where is the cooling system pressure release valve on a 2004 jeep wrangler?
Cooling system pressure should only be VERY (!) carefully released by giving the radiator cap a quarter-turn, but first cover the cap with a heavy cloth cloth or wear leather gloves since the coolant temperature will be over boiling. There is no separate pressure relief valve. Remember too to only add water to an overheated engine while the engine is running. Never add cold water to a hot engine without the engine running as doing so can crack the block.
