2001 Cadillac Seville SLS Question: can a car run smoothly and doesn't smoke have a crack engine block?
It is either a water pump or a coolant hose. - backyard tech
run your engine to normal operating temperature and then chech around your heater hoses where they enter the firewall, if you find one of them to be the problem wait until engine has cooled down to remove the bad hose and replace. - bleonard84
