Ended up switching over to Dexcool in this car, I don't think I would do it again, did it by accident (bought some at advance, just reading the 150,000 miles but not thinking orange doesn't play nice with yellow) and got some brown stuff during the switchover changes. Now it's all switched over this coolant easily makes it between timing belts without a spec of corrosion in the coolant system. Amazing stuff. Get the full strength from advance with a coupon and mix with distilled water.
