Running temp range

[Aussie Mike]

The main thing is to have the fill point for the system as high as possible. Air bubbles will make their way up to it eventually as the water pump pushes coolant through. The old trick used to be to leave the radiator cap off while the engine runs for a while and keep an eye on the level to see if it drops. You might have to wait a while till the thermostat opens but the dropping coolant level indicates the air is being purged out of the system.

Thanks Mike and Sideshow.

Sideshow. From what you are saying it sounds like I have my system set up incorrectly. I have simply fitted a reclaim bottle like the old systems. What should I do? If the water is always circulating through the reclaim bottle, does that mean it needs two hoses? one in and one out?

Stephen,
Find a water hose or connection that is the highest on your engine and after ruining the engine enough to get the chill off it stop the engine and open the hose or connector and air will come out. Repeat this until only coolant burps out and you will find that the coolant stops blowing out the overflow.
As you are using a real engine the place I burp mine is the heater feed as seen in this photo. its to the left of the dizzy in front of the carby.



Also my engine runs at 80*C summer or winter.
Cheers,
Bryan
