Does refinancing an auto loan affect your credit score?

the only thing about applying for a new loan that can affect your credit rating is having the credit score done by new companies. if you have a score done by just two companies that's fine but if you have multiple credit checks this lowers your credit rating. so as long as you ran your previous loan well and paid on time, changing shouldn't be a problem, just don't let lots of companies credit check you. choose one and stick if possible.
