Thermostate or Water Pump?

Replace Radiator Cap

Even if the radiator cap still looks good?

Even if its brand new-manufacture defects. If its the water pump you'll find out in a heart beat.

Try flushing out the cooling system-also could be a partial clogged Rad. and could be a thermostat again.

Or an overfilled reservoir bottle-you should have the cooling system pressure tested to rule out a combustion leakage-meaning blown H/gasket/Crack head abd block

This coolant could be leaking from many places.
With the car at operating temperature, check closely for leaks from all hoses,radiator,water pump etc.
A water pump can leak, and a thermostat housing can leak, but a fault with the thermostat itself won't cause a leak unless it causes major over heating first.

yes of course it could be the pump or "SOMETHING ELSE" :roll:

there is no way anyone here can tell you what's wrong. you have a coolant leak and the only way to find it is to have someone actually look at the car.

When you see the puddle green stuff look between the transmission and engine where it meets if its there a freeze plug is leaking on the engine.

Do the pressure test and observe the reading a quick leakdown will tell you something-whether your cooling system is sealed.
