Is it just to fill up in the water resovoir, until its full? Or do you have to bleed the system somehow?

Or do you have to bleed the system somehow?

Are you doing a complete flush? If so its usually fill, bleed, start, run to running temp, topup....watch'n for the pressure..... and run and check again..

For normal topup from what I can remember fill the reservoir to about the half level point, that what I do on my NA. I always add a little anti-freeze to the mix

you have 3 bleeders. one on the left side hose of the radiator and two on the heaterhoses from thermostat housing.

shall I fill up, open the bleeders , fill some more until it comes water out of the bleeders, close the bleeders and start the engine.. and do it one more time.. does that sound good?

just fill her up and start the engine.

top up as the coolant gets into the system.
when the heat starts to rise you can begin to bleed the air that´s in the system.

I'll add my 2p worth on Coolant For running in tempuratures down to -20 degrees C the coolant should be 50:50 Antifreeze to water preferably de-ionised water. If the minumum tempurature the car is going to see is higher than -20 then a lower proportion of antifreeze can be used, which increases the heat transfer co-efficient of the coolant. I also think that the coolant used should be an OATS (Organic Acid Tecnology Somthing) type as this inhibits the corrosion of the Aluminium that can occur over time, this is also why it's recommended that you use de-ionised water. Hope this helps, i thought i'd pass on the Knowlage i got from a 3 hour meeting/lecture on coolant from a supplier. Regards Rob

I'm with RWinstanley on this one. I have been told never to put just water in the cooling system as it corrodes/furs up the insides, just think of a kettle. My VX was losing coolant a little while ago from a cracked rad pipe. Vauxhall use a brown coloured longlife coolant. Someone on this site made the valid point of not topping up with the blue stuff you seem to be able to buy everywhere. As it is likey to change the properties of the coolant already in there. However if you are flushing the system and refilling most shops will sell premixed coolant so no dilution with de-ionised water is necessary.

antifreeze is obvious, so we left it out in the diskussion we live in the country where icebears are walking on the streets

Afore mentioned supply said ethyl-glycol (Antifreeze) is clear the coolant is made in different colours to try to get you to buy theirs at an extortionate mark up. We where going to us Norfolk Mustard Yellow

The Long-life part is the OATS and should only need changing every 5 or more years.

What coolant do we need for an n/a? Is there a brand or do we just look for OATS stuff? I have seen red and blue in shops but not seen brown.

[RWinstanley]

In truth it shouldn't matter as they are all ethyl-glycol and shouldn't be a problem mixing them*, however the oats is the long-life stuff with corrosion inhibiters. *Although you may get a dodgy colour
