If the timing belt broke on a 1.8 turbo usually the valves in the head strike the pistons. You have to have the head removed to check the pistons. When did the radiator crack? Water pump isn't an expensive part but the rest with work hours and parts will be. Might be able to get a used engine but just make sure that belt and pump are replaced with new along with all the tensionners so the same doesn't happen. Also make sure the oil pressure is good. Sorry for the loss.

Ihave a 99 vw passat 1.8 ,replaced head timing belt,gear,and cover,new water pump,thermostat,and overheats very has 2 fans,1 electric the other is driven by beltsand is with fan clutch,clut

First, Ronald is an IDIOT! DO NOT power wash the engine EVER! If the engine is really hot and you spray ice cold water on it can crack the head instantly! Also, everyone knows' water and electricity don't mix! the ignition control module is $300. A little water on that and its gone!
If your car is overheating, you may need a water pump! The one you got, may have been bad! The rule is, as soon as a car overheats, the thermostat MUST be changed! A simple test would be to remove the thermostat and close it back up! A few dollars for the gasket is all you will spend! Try and run the car without it and see if it still gets hot! If it still gets hot, check the water in the radiator or resivor to see if the water is also hot. If its hot then the water pump is working and you need to check the fans! You can run a power wire to the fan to make sure they are working. There are relays for those also! If they are not turning on, that is most likely your problem! I rebuild VW's for a living!

    Have to replace the timing belt on my 2003 vw passat and would like a belt diagram

    Hopefully you mean a sepentine belt and not the timing belt. There is a diagram under the hood for the serpentine belt. Look on the radiator shroud or close to it. The timing belt requires a great deal of engine disassembly and probably is more that most home mechanics can handle.

    Thermostat/radiator warning light comes on every 3 days - I add fluid to the overflow tank but it is empty after 2-3 days. what's the deal?

    Your water pump is leaking, have it repaired immediately or it will seize up, snap your timing belt, and ruin the engine.

    I can not locate the thermostat on a 1999 vw passat

    The thermostat on your car is located under the thermostat housing. This is located on the engine and your upper radiator hose is connected directly to it. If you are wanting to change it, start with a cold engine, and first drain your coolant out of your radiator, then disconnect the radiator hose from the thermostat housing, remove the bolts that attach it to the engine, and carefully remove it. The thermostat can be removed and the new one installed. Remember to scrape off all gasket residue, and install the new thermostat with a new gasket. Reconnect the upper radiator hose, then fill the engine back up with coolant. Start the engine, and let it warm up and check for leaks!

    Timing belt is hidden under all accessories (alternator, A/C compressor, Power Steering pump, etc.) It is a difficult repair, on many VW models it requires removal of the whole 'front clip' which involves fenders, grill and radiator. Expect $600 -$800 cost. Usually the water pump should also be changed with timing belt - just because to tear engine down that far, it is a preventative step to save future problems.
