this is not normal, first thing to check is low coolant.

Is it a no crank - no start or a crank no start ? Do you know what I'm saying here ? When you turn the key to the start position does anything happen ? starter spins the engine over but does not start . etc..... Two different type problems !

Should be under the passenger side dash.Silver square box with3-4 plugs.

Get a higher temperature thermostat. Fluid in the block warms up first and hotter then mixes with cold radiator fluid this lets it warm faster. Your current thermostat is opening too soon preventing it from warming the whole coolant system,also put a piece of cardboard across the grill to keep the radiator warmer.

is the ignition tuned--cud be weak coil pruducin bad spark or the alternator havin issues-----------the float level is off if carburated-----the injectors not putting out balance-- get vehicle on a diagnostic scan from a private mechanic--it displays values of systems sensors etc. make sure air cleaner is good--pollen cant be seen!

Simply loosen the old one in the radiator to let the coolant run out. After the radiator is empty, pull the old drain cock out of the radiator and install the new one. Tighten the new one up firmly and refill with coolant. Let the engine run to reach normal operating temperature and check for leaks.

Drive until you run out, call a wrecker, tow to gas pump and fill. Sorry, could not resist smart-ass answer. Google your exact model and I bet wiki or others have the answer. Difficult otherwise, as you never get it really empty. Owner\'s manual should say, but I bet you don\'t have one. Dealer should know as well.
