    You need to have your cooling system pressure tested to see if its leaking. It could also have air in the system. Try opening the bleeder on the thermostat housing while filling it up with coolant. When coolant flows from the bleeder, shut the bleeder and top off.

    Removing the thermostat actually makes overheating a bigger problem because the coolant leaving the engine is not hot enough to loose heat rapidly, which means the temperature of the coolant entering the engine is higher than ever. Overheating happens at the point where the cooling system is saturated with hot coolant, which comes a lot quicker when hot coolant is used to try to cool the engine.

    The first big question is whether coolant is disappearing. Until the coolant stays in the cooling system overheating will be a problem. If coolant is disappearing, check for signs of leaks. Most occur at the radiator and show up as white streaks and maybe puddles under the radiator, or at the engine end of the hoses and may show up as puddles, or at the water pump and shows up as a puddle near the driver's side front wheel. The weep hole for the water pump looks like a pencil lead-sized hole in the edge of the engine near the timing belt cover, a few inches up the back.

    If coolant is not disappearing, the top suspect is a plugged radiator. If tap water has been used to dilute antifreeze the radiator is probably plugged with hard water deposits. You can do a flow test yourself with a garden hose. Remove both radiator hoses, put the garden hose in the top hose fitting and turn on the water. It should pass all the water you can put through it without coming back out the top. If the radiator is plugged it has to be replaced – no flush touches hard water deposits.

    Don't forget to bleed the cooling system with the nipple on the top of one of the radiator hose housings on the engine when you fill it.

    The radiator may be plugged.

    Did you do the work yourself? Did you bleed the air out of the system? That sounds like the problem.

    It could also be a bad water pump.
