If radiator coolant backup in reservoir is there any reason other than blown head gasket if cap and thermostat are good?

If you mean coolant in the engine oil reservoir, then yes, it is slightly possible, but very unlikely, that the engine block water jacket has developed a hole between the water and oil pathways. Other than that, the head gasket is the only place where oil and water can come in contact with each other unless your car is equipped with an engine oil cooler which is internal to the radiator (very unlikely).
If you are referring to coolant being in the radiator overflow reservoir, it is supposed to have coolant in it. When the engine is cool, the overflow reservoir should be around half full.

What causes coolant reservoir overflow or backup?
The radiator cap could be the cause of coolant reservoir overflow or backup. Have the cap checked to see if it is bad.

What causes coolant to backup and spill over in the reservoir until its all gone?
the reason why the coolant is spilling up over the reservoir is because the thermostat needs to be replaced because when the engine needs water the thermostat heats up from the engine and causes the springs to expant which opens a seal to allow the water throughout the engine i just realpaced the thermostat in my volkswagen
Why is your 97 firebird overheating?
More than likely the thermostat is stuck closed or staying closed too long. If it is truly stuck closed, coolant will overflow out of the the reservoir tube as the engine begins to overheat, however if it heats up and sometimes cools off the thermostat could be failing. The thermostat is located beneath the waterneck where the upper radiator hose connects atop the engine. Two bolts will remove the waterneck. Expect 1 pint or more of coolant to backup through the opening when removed. Drain some of the radiator using the drain plug on the bottom of the radiator, or put a large drip pan beneath the car, expecting the engine to get wet. FOR THE LOVE OF ALL, do not let the distributor get wet...its on the front of the motor beneath the water pump. Additionally, there is an airdam affixed to the underside of the front bumper. This acts a diverter for the flow of air into the radiator. If this piece is severely damaged or removed, the radiator will fail to cool the engine properly.
Why does antifreeze backup into the overflow tank?
Heat from the engine causes liquid to expand. It used to overflow onto the ground if it caused enough pressure to open the radiator cap. The overflow tanks were installed to automatically catch and return the coolant to the cooling system.

Which antifreeze-coolant would one use for a 2000 Jeep GC Laredo?
depending if you live in mainly cold or hot weather area, cold weather-- use a 50-50 dexcool [orange liquid] straight in backup tank and 50% antifreeze/50% water in radiator, do not add water to backup tank. Hot weather-- [my recommendation] use a 50-50 dexcool [orange liquid] straight in backup tank [no water], and 20% antifreeze/80% water plus add liquid called waterwetter [pink liquid] to radiator, this will greatly keep engine running cooler by almost 15-20 degrees
