I am such a spaz :parhmph:
Last night I set about renewing the coolant in the V70. So, drained off the old stuff, the set about disconnecting the radiator hoses as I wanted to flush the system. Bottom hose clip was rusted solid but got that off. Flushed the radiator through with a hose. Then took the thermostat out and flushed the engine through too. Put everything back together (all 3 jubillee clipes replaced with brand new ones), and mixed up my coolant. Got a 4 litre bottle of genuine Volvo coolant and mixed this 1:1 in a bucket. Only mixed 4 litres worth to begin with.
So, started to decant the coolant mix in the header tank, taking it slowly, squeezing the hoses as I go. Got ~3.5 litres in.
Can you spot what I've done wrong yet?
The system is supposed to hold 8.8 litres of coolant (according to Haynes). I've started with x amount of clean water in the engine from the flushing, and maybe a bit in the rad, which I've forgotten to drain off before refilling. That means my 1:1 solution mixed up in the bucket is no longer 1:1 when combined with the water already in the system. Goddamit :slap:
I've done some calculations (my head hurts now) to figure out what my effective ratio is now and what I need to do to correct it (unfortunately not as simple as just draining some off and chucking the rest of the neat coolant in). I think with what I have left over, I can get it just on the good side of a 1:2 ratio which is good enough for -20 degress and is the minumim mix for effective corrosion protection.
Should have been something so simple :rolleyes:
