Hello, Can anybody please confirm if the cooling system for a 2006 2.4 ltr petrol engine is a closed / sealed system. If not where do you put the water / coolant in.

Many thanks.

Chris

I have not looked at the manual yet but my first choice would be the black arrow, 2nd the red arrow.

The red arrow one has 'Engine Coolant' which is a bit of a giveaway and the black one looks to be the expansion tank and should have max and min markings on.

I hope this helps.

In this picture:

Top-Left is for the brake fluid

Bottom-Left is for the engine oil

Bottom-Middle is for the engine oil dipstick

Bottom-Right is for the washer fluid

Middle-Right is for the engine coolant with a caution about steam (I expect)

Top-Right is for the engine coolant expansion tank, with the min and max marks on it, probably for when the engine is cold, but check the manual for that.

Hopefully someone can confirm.

Hey Chris, sounds like Gamith has given a pretty thorough rundown. The cooling system on your 2006 2.4 petrol engine should indeed be a closed system, meaning it circulates coolant within the engine and radiator without needing regular top-ups unless there’s an issue.

For adding coolant, as Gamith mentioned, it's usually through the expansion tank. Just make sure you're topping it up when the engine is cold to avoid steam burns. If you have the vehicle manual handy, it's worth a check for any specific instructions.

Let us know how you get on, and if everything checks out okay. It's always good to hear how these things turn out!
