Why is there a loud crack crack crack like a stone hitting metal from the back of the car near the exhaust when the engine is turned off and cooling down?
Your hot exhaust is cooling down and the metal is making a ping sound, chances are though, that your exhaust is possibly getting too hot, or has some loose components inside or bolted to it.
If your exhaust rattles at all, you may need to replace the muffler, and if you car has a trouble code related to misfire, or catalytic converter there may be too much fuel in the exhaust and is too hot.
What else can I help you with?

What could cause a loud clicking sound in front and back of a 1995 ford for about 5 minutes after motor is turned off?
I will take a stab at the answer....... Do you live in a hot climate? If so, when the engine is hot and possibly a new exhaust was installed, the clicking would be the exhaust cooling off. Sound good ?
Why is a cooling system required in a motor vehicle?
Because quite a lot of the energy used by a combustion engine gets turned into heat whether we want it or not, so a cooling system is needed to keep the engine from overheating.
On a 1993 Pontiac Grand Prix 31 v6 is the intake manifold on the front and exhaust on the rear?
On the front and rear of what?? The Air Intake Manifold is on the TOP of the engine. the Exhaust Manifold are on the sides of an engine. On a front wheel drive vehicle, the engine is turned 90 degrees, so the exhaust manifold appears to be on the front and back of the engine, below the valve covers.
Is there supposed to be popping noises coming from exhaust pipes?

Does thermostate control double radiator fans in Honda cr-v?
One of the fans operates independently of the air conditioning system. The other fan will only operate if the air conditioning system is turned on and the engine needs extra cooling to exhaust the heat transferred to the engine coolant by the operation of the A/C. They both are tirggered into operation by thermostatic switches but not the same switches. They are independent of one another. CAUTION: Do not confuse these thermostatic switches with the actual cooling system thermostat contained in the engine block that controls the flow of the coolant.
What does an engine block do?
It forms the 'body' of the engine - it is a lump of metal machined to take the crank shaft, oil and cooling ducts and the pistons. It is where the 'explosions' of ignited fuel are contained and turned into rotary motion.
