Checked the water level and it is now just a tiny amount above max.
I think the water gauge always stays under 70. I will check this when I go out again and report back.
While I have your attention
is there a faq for general up keep of the g40..
I will be changing the oil every 5-6000 miles with genuine parts.
At how many miles should I be lubricating the supercharger?
The car is currently running 150bhp and it is rapid!!
thank you for the replies... much appreciated.
