Changed the water pump on a 1994 F150, in a matter of two months have went through two radiators (going on three) because the fan is shoved up against the radiator every time you accelerate hard or hit a pot hole????? I thought it could possibly be a broken motor mount but wouldn't that cause the motor to move side to side not shove it forward into the fan? Desperate and broke!!!

 

Are you sure you're getting the radiator(s) in the lower support holders?
