24 valve Header Tank

Good morning folks.
The sun is shining and my red Cossie is on the road with the Rad topped up and sporting a replacement Header Tank thanks to P J  . The long hunt is over and I can enjoy this excellent car without continually glancing at the Temp gauge. Chuffed!!
Interestingly, she has always suffered from the Heater not maintaining Temp, no doubt an airlock. I have tried all the current remedies to date with not much success. Well this time I raised the whole of the drivers side by simply putting those wheels onto the kerb raising that side aprox. 4 inches, started her up and let her warm up on tick-over. As the pipe that runs from the Temp gauge to the Header Tank warmed up I took hold of it and I could feel the air bubbles as they rose. When, finally the slight pulsating sensation stopped - no more air - I revved the Engine a few times, checked for more air and left her to cool down overnight.
In the morning there was no drop of Coolant level so I took her for a good 20 mile drive and one of the first things I noticed was that the Heater kept warm very well, not perfect but getting there. Much, much better than ever before. I don't suspect any blockage as she will reach high Temp.
It is nice and cold this a.m. so I might just put a couple of 2" blocks on top of the pavement to raise her just that bit more and repeat the above.
Happy week everyone.
Mike

Have you tried running the engine with the car parked facing uphill ?
I was told this is the best way of working airlocks out of the system.

The "Jonnycab" method worked for me. See page 5 of "How to do things"

Here is the link to the Johnnycab method
The photos have been removed due to changes with Photobucket but the script is sufficient and the photos, if I remember correctly, simply showed the clear plastic tube up above the engine and full of green (antifreeze) water.
