Radiator Coolant Ratios

[kraza]

Hi All,
Just changed the radiator fluid in the 03 GU, 50 / 50 mixture now its taking ages for the heater to warm up, (if you can call it warm) is it the ratio or do I start looking some where else.
What is every one else mixing and what sort of coolant is being used. It was fine before, and I think the ratio was 30 / 70water. Planning to change the ratios on the weekend

More like 30/70 mate - not half half ... although in saying that, I'm not sure of the issue it causes.

I would make sure you do not have an airlock.

Thanks Yendor that was the problem

70% coolant to 30% water is about max for most coolants. Up here it gives the max freeze protection.
