Yes. Prestone’s coolant is guaranteed to be compatible with all cars, vans or light trucks. Thanks to its unique and patented formula, Prestone Coolant/Antifreeze remains the only coolant on the market that can be mixed with another product within the cooling system without causing damage. That means there’s no need to flush your car’s cooling system before adding Prestone Coolant/Antifreeze; simply pour the product into your coolant reservoir – it’s that simple.
I can't say I've used this myself but its technical recommendation looks to be compatible so I 'd say that you're OK
