I Need some help before i take the car to the stealership again but this is whats goin on and what was done prior.... I had my crossover tube replaced and i jus replaced my radiator now my cooling fan isnt kicking in and the car is starting to overheat when sitting......how do i find out if the solenoid for the fan has gone bad or if the system jus needs to be bled.....jus shootin in the dark right now and does anyone know who sells a replacement fan assembly if i need to replace the whole thing......and the fan was working before i had the crossover tube replaced it would run all the time but also i jus turned on the a/c and it didnt kick on either i hope this post isnt confusing.......jus to be more clear i'm want to find out how to diagnose the hydraulic fan system to find out what needs to be replaced.....thanks
