Try running it up to temp at idle with the hood up and waching for pin hole leaks.

Once it heats up (make sure the cooling system is full first) check around the entire cooling system.

Have you checked around the water pump weep hole really good for burnt coolant residue?

Sorry I didn't have anything more specific, but it has to be going somewhere. And those slow leaks can hit hot engine components and evaporate befoer they can drip or make a wet spot.

Check near the exhaust manifold, if it leaks there the exhaust will burn it away with no signs of a leak. If you can't find a leak you may have a blown headgasket.

This happened to me once. Turned out I had an air pocket inside the engine so it was not completely full of coolant. When the engine got hot the thermostat would open and suck the coolant into the block. This made my coolant level look low and since there was not enough coolant anyway, it would get hot. Try taking off the radiator cap, let the engine run and as it heats up keep adding coolant. Once you have been at normal operating temp for a while and the rad is full you should be good. Hope this helps.

BTW: If this does not help, pull the thermostat and check it. I have gotten bad ones before and a buddy of mine even installed one upside down.

It could be an "air lock" in the system.

It could be a bad cap.

It could be a bad thermostat.
