Sorry if this is a redundant question. I find my coolant a bit under min. Can I top of with Pentofrost without diluting or must I go ahead and dilute with distilled water? Thanks for your help. Thomas

If you are just topping it off you will be fine adding straight coolant.

Thank you for your quick response. This is the first time I've had to add coolant since I inherited this car from my father 3 years ago. How much is more than just "topping off". I'm getting the 1.5 liter bottle and have no idea how much - an inch or two below the min line requires to return it to level.

You will be fine. Just monitor the level closely over the next week to see if it continues to drop. If you need to add again you will have to figure out where it is leaking.
