Curious minds want to know:
How do you know you are using the "wrong coolant"?
Any telltale sign?
What can go wrong if you are mixing in the "wrong coolant"?
E.g. top up the coolant level but have no idea what the existing coolant type/brand is?

Just want to know what to buy when it comes time to add some.

I can only speak from a Big Rig perspective with 10's of Gallons of capacity... if you mix the wrong stuff in those, you can turn it to Jello and have a real problem. Hasn't happened to any of my trucks yet, but I've heard stories.

Using the wrong coolant type will cool your car for a time, but there is a very really possibility it will cause serious corrosion, degrade parts, and possibly damage the water pump, clog the radiator or heater core and could cost a bundle to rectify. It’s just not worth the risk.

I suppose that is why they can sell the "OEM replacement coolant" for 5x the price of some "generic coolant"...
Since my 453 is using a Renault engine, I would lean toward the cheaper "generic coolant".
Note: I am not an engine coolant expert. It is just a personal preference.

Khlam, I’m not necessarily endorsing OEM products, just the recommended type for the car.

I don’t have deep pockets so in many cases, the OEM versions are too expensive for my tastes too

Looks like that I will be going with Prestone. Thanks everyone for the follow up.

Rock Auto...

Just watch the shipping.

Zerex G-40 can be found at NAPA...

Looks like Zerex G-40 is the way to go, I spoke with the service person who only deals with Smart Cars where my car came from when new and always serviced there and he said just make sure the coolant is pink and not green like prestone because if you mix them all is fine until you turn off the car and when it cools down the coolant then turns into a jelly like substance. They had that issue with the newer models.
