Getting hot after Dawes needle and 3"

[Clunk]

Million $ Question then, is how or what is the best way to bleed the air out?

Fire, lots of fire

When you re do it turn the heater on think they over looked that part
and have you checked the water pump it might have give up the ghost

Havent seen any telltale drips at all, and theres no noises?

park it up hill and cut the bottom off a coke bottle tape that to the radiator filler neck.
Get up to temp with the heater on, squeezing top hose every now and then.

Is the viscous fan working as it should???

You could buy one of those radiator bleed kits @Hodge used recently
no idea where he got it. a gift I think

Well, if it was done properly they'd use vacuum refilling unit where the created vacuum in the cooling system would sucks in correct amount of coolant from a container and without air pockets....

I've got that unit in my shed now as I have 4 cars to look after....

Your best bet is to warm the engine and then carefully slacken off the header tank (expansion) cap and watch for any depressurising/air/coolant escaping. I suggest do it slowly and have rubber gloves on so you don't scold yourself. Really be careful, I advise you practice the art with engine cold first so you know how far you need to undo the cap. once there is no longer any pressure coolant should be staying in while engine is idling and you can watch for air bubbles....

You could also create a bleeding aparatus from a spare/another cap drilled and/or with plastic hose inserted/sealed in the cap/header tank opening and the other end of the hose submerged in the cooke bottle with a bit of water in it so you can see it bubbling. This is home made "check for pressuring the cooling system" device. I also repurposed old Tee Kay head check combustion leak detector for such purpose but that might not be an option for some.

The other way is to park the truck in such way that air can escape via header tank being highest point of cooling system with the cap undone.

When I had an air lock in mine I kept pulling over every 2 km and undoing header tank cap until bubbles/air escaping pressure stoped. It took about 15 km....

So I ran the ol gal with the heater on today (Farkin shitty humid day to do so). Got home waited for it to cool and cracked the header tank @Rumcajs put a queen sized sheet over it........empty took about 3/4 ltr maybe 1ltr to fill. Ran it with all 3 caps off and coolant started to come out the radiator and splash me in the eyes (HAHAHA NOT COOL MAAAAN). Put that back on and left the header tank open and the over flow tank open and ran it up to 82C no movement, no bubbles. So I'll run into work tomorrow and see if the levels drop again.

You dont need to have the heater on mate. These dont use a heater tap, so coolant runs through the core regardless of what setting you have it on.

I think that leaves only [maybe] to service your MAF and check your viscous hub.
Shouldnt need a fan at 100 kph , OOI does it have that bottom section of shroud
fitted its about 400mm by 50mm. plays a big part in the whole fan shroud thingie lol

[growler2058]

Yeah shrouds all there

Sorry for late reply. The spill free funnel kits are available everywhere. Example here...

I have followed nissannewbys advice on mine (identical cooling setup as the 3L CRD). After initial top up and bleeding just by idling idling the motor, they eventually rid them selves off air after a drive or two.

I tried using the funnel on mine recently @ the radiator. And it certainly helped with the initial bleed after filling the system up.
The park up the hill trick will only work so far on these due to the header tank design. Header tank is the highest point when car is on level ground. No need for uphill parks.
They are designed to self bleed. Fill up radiator and header tank to max. Fill overflow tank to between min and max and then run the motor till thermo opens. Go for a drive and monitor the coolant level... Top up if necessary. Just make sure the overflow coolant is present for the header tank to suck out of... Mine settled after about 24 hours or so...
