HRF1T2020 Posted November 27, 2022 Share Posted November 27, 2022 Hi Wondering how many have the Yellow coolant opposed to the orange Yellow seems to be a P-OAT which seems it can be used to top up orange but not the other way around, I’ve emailed local dealership for their spin on it From Handbook WSS-M97B44-D is orange coolant. WSS-M97B57-A2 is yellow coolant. Yellow coolant may appear fluorescent green in some cooling systems which is a normal characteristic. Note: The WSS-M97B57-A2 yellow coolant is compatible with the WSS-M97B44-D orange coolant so all vehicles with orange or yellow coolant can be serviced with yellow coolant. However, if the vehicle was manufactured with yellow coolant it must be serviced with yellow coolant to maintain a longer service life. Can only find this in hunting for some Prestone LOYAF2100LGBA Coolant/Antifreeze - Ready to Use 1lt https://amzn.eu/d/fMhw06n Quote Link to comment Share on other sites More sharing options...
