Sounds like you're very low on coolant. With the engine cold, remove the radiator cap. Start the engine and fill up the radiator with coolant(50/50 mix of water and antifreeze). Wait for the thermostat to open as evidenced by the upper radiator hose getting hot. Finish topping off the radiator by filling it to the tippy top. Replace the radiator cap and fill the plastic recovery tank to the "full hot" line. If you're not low on coolant it may be a bad water pump not circulating the coolant properly or at all. HTH. -Jim
