I have recently bought my R and noticed that the coolant reservoir was low. I asked the garage I bought it from and they are adamant it should sit like this although other people tell me it should be full and others half full. i'm totally confussed and would appriciate some advice please. Where should the level be when cold and also hot?CheersMatt

50/50

look for the max line on the bottle, fill it to there when the engine is cold.

Don't you mean fill it to the max line when the engine is hot matey ?! :lol:

It's an expansion tank and so, will fill up with water as the water gets hot and expands, when the engine heats up.
I normally fill mine to half way between the min and max line, when the car is cold and, it never goes over the max line, when hot.

No.

IMO and is what myself and my dad before me has always done (Mechanic) is fill to max on cold engine. The space above the max is enough for normal expansion of the liquid. Any more expansion or loss of fluid will be because its running hotter than norm.

Filling when cold to the max allows you that little bit more time and water useage if required.

Each to their own though i suppose.

After installing my hybrid copy fmic kit, there's no place for my OE bottle any more. I have a 591 mL pop bottle shoved in there, but it's not enough, the coolant sprays through the top when its hot, and it sucks almost all of it back in when the engine cools down.

Any alternatives?

If you are going to relocate the expansion tank make sure that the outlet i.e. for the expanded water is higher than the top of the radiator or else you wont fill your rad i.e. wont have the adequate cooling.
