I'd give one a shot if you find them at that price
This.
Something cheap. If it doesnt work youre not out much. Id buy multiple bottles for a truck.
Get the one thats antifreeze compatible. Its too much effort to flush.
If its a no go, theres nothing that says you cant just keep adding coolant. If youre in a warm area, just feed it water.
Please report back.
