Coolant type for Pontiac Transport (van)?

Question

Hey guys,

I own a 1998 Pontiac Transport (Van). Similar to the Montana, anyways my engine coolant light is on, I was just wondering what type of coolant would I put into my vehicle? Book didn't come with vehicle.

Answer 1

You can do one of three things; first look under the hood at the radiator cap or the coolant over flow tank, second look at the color of the coolant. if it is a re-dish orange color it is dexcool. if it is a green type it is regular coolant. and if all else fails just call the dealer and ask for the service dept. most people will be willing to answer that type of question.

Answer 2

it is supposed to take dex-cool, unless your system has been flushed and changed over. if you can visually see your coolant...dex-cool is orange and normal coolant is green. if you can't tell either way or its too dirty to tell and you are not the original owner, I would get it professionally flushed, with chemical, and refilled with either of your/ or your mechanics choice. if you mix the two coolants it forms into acidic sludge and could ruin the whole system, intake or block.
