Question

On my 2002 Dodge Ram 1500, will this overheat something if not fixed ASAP? I got the engine code P1491

Answer 1

Hi there,

This code is normally a result of a problem with the A/C condenser fan on the truck. It should have a belt driven cooling fan, so it should not cause the truck to overheat under normal driving. If you are driving with the air conditioning on then it is possible you could have an overheating issue.
