97 buick skylark
v6 3.1ltr
refurbished engine put in a few years ago and the mechanics put in the prestone universal yellow. haven't had any problems with it.
i need a new coolant reservoir and am also going to change the hoses so i am wondering if i should put in regular green coolant. previous engine had intake gasket problems so i am reluctant to put in dexcool.
stay with the yellow?
go with the green?
