1996 BMW z3 1.9 just blew top hose off previous overheating problems. Could it be stuck thermostat?

Hoses wear out , replace it . That hose is under a lot of pressure and heat and everything wears out and has a life. I would say that was a helluva hose to last that long and would suggest you look at all your hoses and belts especially if they have never been replaced.

Where is the thermostat located for the 1997 bmw z3 roadster 2.8 engine

It is on the front of the head, facing the radiator.
Follow either big radiator hose, they are both attached to the thermostat housing.
Your thermostat housing is probably plastic. If so, don't re-use it because plastic housings of that vintage shrink and warp. Buy a new plastic or aluminum thermostat housing.
On a car this old, consider replacing every plastic or rubber part you touch, unless you know that the part has recently been replaced. I have a couple of '97 328s, and I never put a plastic or rubber part back on the car without replacing it. Saves a lot of time and repairs down the road.

My 1996 z3 is overheating while I have replaced water pump thermostat, and radiator, car still overheats

Check the electric fan(s) if equipped. If it has a belt driven fan, replace the fan clutch. Also rechecking the thermostat is a good idea too, they are sometimes bad right off the shelf.

Where is the thremostat located

In BMW 328 To locate the thermostat follow the hose from the right side of the radiator to the motor at that connection there is thermostat.There should be 3 bolts which you will have to remove to take off the thermostat. In BMW 328i The thermostat is located behind the viscous fan and approx 9inches above the center of the fan. The viscous fan drives the water pump and the thermostat housing is just above the water pump at the front of the engine. The thermostat is a one piece unit and is a bit expensive £55 at dealers £42 independent. You will need to remove the viscous fan to get at it there are special spanners for this and its a 30mm socket left hand thread ( screws off clockwise). Thanks. you can rate this solution and show your appreciation.
