I have no experience with co-signing loans and no prospect of any experience. However, out of idle curiosity, what happens when the co-signer of a loan dies? My impression of the term "co-signer" is that the co-signer is a sort of back-up for the signer of the loan and that if the signer defaults then the co-signer must assume the liability. But someone might die after co-signing a loan and a default by the signer might occur years afterwards.
