alright guys i know this isnt the right site but my mom traded her mustang

for a 2004 dodge ram 1500 4x4 5.7 lt truck (sorry for the long explanation) any ways it was owned by a 70 year old so we thought it was in good shape well cosmetacilly it is but the pedals (adjustable) dont work (not a big deal) the power steering rack leaks fluid bigger of a deal but still not as bad as the
RADIATOR which has corosion on it and is leaking badly dodge says they wont fix it it wasnt there
2 weeks ago when she bought it i say b.s. there is no way that this happened in two weeks and yes i checked the whole truck and asked about the leaking steering rack but i think they just plugged the whole so they wouldnt have to worry about it but to the point does anyone know were i can get a radiator cheap.
