What strength antifreeze?
« on: 20 December 2010, 20:08:34 »
Lost most of it - about £8 worth in 1/4 mile.

If the cooling system is 1/2 full and topped up with water how effective  will the mixture be?

Well below the recommended strength for the temperatures we're having now Martin I would have thought! :o Best to top up with at least a 50/50 mix, erring on the side of generosity tbh  :y

If it ain't broke keep fixing it 'til it is!

Only got water here now - I could underfill to VX IF they have any.

Car is about 50% and about 1/3 to 1/2 filled

If you can manage without the car I'd leave it as it is?  At least what you've got in is the correct ratio.  :y

From memory a 50:50 mix gives protection down to -40 Deg C, 25% is about -15 Deg C so a little to close for comfort at the moment

Especially bearing wind-chill factor in mind.  You might be okay parked up, but as soon as you move the rad may freeze up before the thermostat opens.

Elite now gone.  Bought an X-Type 4x4.  If there had been an Omega 4x4 I would have bought that instead.  We really liked the Omega, but I wanted 4x4.

Sounds like a golden opportunity to fully drain it, flush it, then fill with fresh 50:50 - which will see you good for the next 2 yrs :y
