I want to add some anti freeze to my 1998 club wagon with a 5.4 engine - want to make sure I add the right stuff - the owners manual states to use E2F2-19549-AA - I can't find any reference to that number on any brand of antifreeze - does anyone know if this stuff is the xylene glycol that older cars use - like Prestone which states that it is compatible with all other antifreezes - would appreciate your thoughts on this - thanks - Joe

 

I think you mean E2FZ. I believe that’s gold colored coolant of which Zerex G-05 is compatible. That’s what came in our fleet maintained ‘07. I don’t recall anything that color from Prestone or Peak.

The designation E2FZ-19549-AA should refer to the green stuff. Considering the OP's model year is 1998 it would have been installed from the factory.

I don't know it later year formulations would be acceptable or compatible so I myself would use the green stuff without hesitation.

 

Right, I think the gold H-OAT came around in 04
The orange around 2011
P-OAT yellow now
Get it from the dealer to be sure

 

Oops, thanks for the correction.
