More motor problems!!!

I had a blown head on my last motor.....well I least i think that I did. All the signs were their.Weak vacum press,overheating, resirvor tank overflowing or not suck fliuld, and last but not least oil in my new C&R radiator. :mad:
So what did I do, I got a new-used motor from a well know shop. The motor had 88.000 mile on it and very clean. They should me the head with the value cover off, it look very nice and clean :iceslolan. So as it's getting hot over hear in Cali I mean realy dam hot. I notcie that my water temp gauge(custom) is a steady 201f degress. Which in my mind is too hot! I pop the hood open with the car idleing and notcie that the fan wasn't come on. That very weekand I dicieded to do a complete flush off the cooling system. Flush radiator with flushing fliud, new honda thermostat and flushing of the block! I can't be the water pump because it works or it dosen't. I did notice that the resirver tank was emtpy so I filled it up 3 times whats up with that :banghead: . I wanted to now whats the problem before i go back to the shop that swaped it
Any Ideas??? :naughty:

maybe the block is cracked and the coolant is just mixing in with your oil and shit instead of circulating through the motor. your temperature switch may also be faulty if you know the fan is good. but if some shop installed the motor for you, there has to be some kind of warranty that it will work.
