Question

had radiator flushed about year ago and just noticed they put green coolant in it and it was a red/orange color before should I change it or is the green ok

Answer 1

What Jeep recomends is Ethylene type with a 50 / 50 with water , make no specification of color. Having regular coolant or conventional coolant which is green and you put a long life coolant  red / orange at a certain mixture level it can jell up. Example are the GM recomended for their vehicle is a Dex cool. This is a famous coolant for dissolving the intake gasket , so owner removed it out, If the Dex cool is not properly flushed out and conventional green is addded it tends to jell. This is not saying you have Dex Cool just an example certain coolant are not compatible, If you want to make sure Use Prestone look for the statement 'Mix with any color antifreeze". it nicknamed is universal coolant.
