This week on The Best of Car Talk, think an old Volvo is indestructible? Meet Arlene’s daughter: destroyed the cooling fan and made things worse by pouring cold Mountain Dew into the overheating radiator. Can Arlene fix the Volvo and her daughter? Elsewhere, Glenn’s unorthodox shifting is earning him glares and dope slaps from his wife; Kate’s mechanic husband can’t figure out her car’s starting problem, despite the fact that he’s shopping for a bigger boat; and Freudian therapy techniques may save Tom and Ray, as they try to solve Chet’s steering and transmission problems. All that and more, this week on The Best of Car Talk.
