I have a related question here;
Had a look at my radiator reserve tank yesterday, and it is empty.
So, bought a 5 lt bottle of Nulon Long Life Concentrated Coolant (green)
However, I dont know how good to add this into the system, as I dont know what sort/brand of coolant is in at the moment, which may result in clashing two chemicals.

So, can I simply add some water instead untill I totaly flush my system and replace with Nulon?

Also air locks are a common problem, so an easy way to eliminate this is to run the car for 10-15 mintues with the radiator cap off. You may require a top up.

make sure the heater is on as well.

Yes yes I know this thread is a little old, but...
What if the heater core is disconnected / bypassed (cause it's knackered and I haven't got around to fitting the replacement) therefore having the heater on won't do anything, will this cause issues/not do the job properly?

Your heater is not connected, so coolant can't enter your heater core, so you don't need to bleed the air out of your heater, so you don't need to turn your heater on.

Cheers once again Phil, didn't know about turning the heater on to bleed in normal situations (when there's a core working that is).
