On my 86 been trying to get everything sorted on it and the cooling system is giving me probs, I just bought a new rad cap stant part # 10230 but still having problems, the car gets hot and overflows the overflow tank and it allows all the coolant to pretty much go on the ground. The thermostat is good I put it in boiling water and watched it but it's a 180° Stat instead of the factory 195°. Amy help is appreciated

Fill system correctly?

I would suggest the obvious things first... such as filling and "burping" the cooling system properly, and ensuring the coolant reservoir is filled to the correct level. You want to make sure no air is trapped in the system.

* Make sure rad cap is the proper one for Fiero use. The catalogs are wrong! You want a non-vented one,
* Check that the overflow tank and the small hose to the rad are both in good shape. Otherwise air gets sucked in.
* Ensure that coolant level in overflow tank is at the "Cold" level.
* Position rear end of Fiero higher than the front.
* Remove thermostat housing cap and thermostat... and then add coolant to thermostat housing with rad cap also removed until coolant runs out the top of the radiator.
* Re-install rad cap.

* Continue to add coolant until you see the level come up to where the thermostat normally sits.
* Put thermostat cap on and turn just barely enough to hold cap on.
* Start engine and run for about 30 seconds.
* Remove thermostat cap and check coolant level.
* Repeat last four steps until coolant level no longer drops.

* Re-install thermostat and thermostat housing cap.

As long as there are no blockages anywhere in the cooling system and the water pump is circulating coolant, you should be good to go.

I've tried both of those and neither worked for it I'm starting to think it has a bad head gasket or cracked head.

Bad gasket or cracked head I would think would mix oil and coolant and or burn it out the tailpipe as white smoke.
