I have 2013 dodge grand caravan with a 3.6 engine .I notice oc cold start that I hear a squelling noise from engine which only last for a few seconds. This only happens when the temp is very cold and does not happen startup later in day
It is most likely because of a cold belt. Easy to test. Take belt off and start the car. If theres no squeal its the belt. If there is still squealing, you have bigger problems.
