coolant top off

  1. Low coolant, just top it off?

    RAM 1500 Diesel General Discussion
    Maybe this is a dumb question, but I'm new to diesels and have never had to top up coolant in a gas vehicle before. With all the talk on here about black sludge in the coolant, I checked mine. It's still pink but about an inch low of the cold fill line in the reservoir. Should I just top it...
