Here is the recipe for success to your problem:

1) get a big box
2) pull off all non-stock parts off engine/compartment DROP IN BOX
3) remove water pump DROP IN BOX
4) remove thermostat DROP IN BOX
5) Purchase new parts: water pump, thermostat (160), plates
6) Purchase/acquire: factory clutch fan or flex fan, stock radiator shroud

This is a min configuration that should solve the problem.
BTW: you can leave the t-stat out for max cooling if you like.
T-stats stuck shut will over heat your car; stuck open
don't hurt the system from an overheating issue.

Love da blue

Good luck!
