LANDCRUISER 13BT thermostat trouble HELP!!!

Help! Took the old 70 series for a 300km blat down through Farlie today and the engine temp wouldn't come up. Checked water levels and thermometer wires from thermostat, all looked to be in working order. picked up a new thermostat from repco on way home and replaced old one once she cooled down. Old thermostat had cracked. Replaced gasket and sealant on housing.
How do I know if I got the air out of the system after changing the thermostat?
The main radiator hose was fizzing around the edges after I ran it up to check for leaks, should I use Gasket Goo on it to seal it up?
Any other advice
Cheers
Colby

hmmm swap it for my overheating cruiser lol! for the extra few bucks get new top radiator hose, eliminates worry of top hose failure. to get air out just run without cap like any other car/4wd untill it opens and flows coolant??

To get all the air out of my 70 (and my Surf before it) I leave the rad cap off overnight everyday for about a week. Most of it can be removed by running it up to temp with the cap off initially. It's air-free when you don't have to add any more coolant.

Also I find drilling a couple 2mm holes in the thermo makes it much easier to remove any air, at the expense of a slightly slower warm up.

The hose appears to be in good condition. It's just not sealing properly on the thermo housing.

Thermo housings get eaten away if motor has been run without coolent in the water at some stage. You should have plenty of meat on your housing where the hose clamps on if not you may need a new thermostat housing as well
