coolant replacement

Post by dplum »

Hi,
Have drained and flushed through the coolant on my 1988 DG 1.9 T25 for the first time as per the haynes manual.

all seemed fine as flushed through, however once putting in the new coolant i have only got around 6 litres in and the tank is full to the brim already and doesn't seem to be going down no matter what i do to squeeze the hoses etc to remove air?
Both the radiator bleed screw and thermostat bleed screw are open completely.
is there any trick to do this, or something i've missed?
thanks

Was the system totally empty as there should be 16 litres of coolant in the system?

Try using Baxters tried and tested method for bleeding the system.

Baxters tried and tested method lol......This method or similar was used back in the day....nothing to do with Simon although his writeup is useful for those not in the know.
Besides, this problem has nothing to do with bleeding, just that most of the water wasn't drained before refilling....and unfortunately it is easy to fall into this trap. Problem is now the only thing you can do is to drain some of the 30% mix in order to add yet more neat antifreeze to make up the shortfall in strength, basically ditching several litres of weak mix to add neat to get strength 50:50.....you will need to buy several more litres as what you have will not be enough.

6L of neat antifreeze isnt NOT enough (if thats that you put in), IMHO...

Drain some more out... you need a good 8-9L of neat antifreeze in there... :wink:

Refered to as Baxters method.......Strangely, back in the early 80's, one of my coolant bleeding methods was adopted by VAG group after many reported problems bleeding Audi 200 Turbo's, I was sent a letter of aknowledgement by VAG Milton Keynes after my advice found its way to Audi technical.
I'm sure somewhere there will be someone quoting the Donzé method...lol.

And if you didn't already know who lol was, he's the context in which I wrote my reply...as in, not to be taken too seriously...you obviously missed his meaning.
