Default Help please - need official coolant bleeding procedure asap

Hey guys - been awhile since I've been on here, and don't have access to my old email account / password so I had to setup as a new user. Long story short, I just got my rebuild motor back from the machine shop for my 01 D2, and it's installed along with new radiator, thermostat, water pump, etc. That said, my mechanic is having major issues bleeding the system. Could someone please post the procedure? I've searched the forum but cannot find it for some reason. Thanks in advance -

ps - DiscoMike, I see where someone posted a couple days ago and you offered a phone call. I can PM you my number if that offer is open!

Steve in VA

Rave:1-4 had nothing to do with bleeding

5.
Release top hose from retaining lugs on the fan
cowl, leaving the hose to rest on the lugs.

6.
Remove bleed screw from top hose.

l
'A' From 03 MY

l
'B' Up to 03 MY

7.
Unclip the bleed hose from the battery box.

8.
Remove expansion tank from its mounting
bracket. Slowly fill the expansion tank with
coolant, approx. 4 litres (7 pt).

9.
Raise the expansion tank approx. 20 cm (8 in)
vertically, coolant will drain into the system.

10.
Refill the coolant expansion tank until a steady
flow of coolant is emitted from the bleed hole.

11.
Fit the bleed screw then, with the expansion
tank still raised, continue filling the system until
the coolant level reaches the base of the
expansion tank filler neck.

12.
Fit expansion tank filler cap, fit the expansion
tank to its mountings and clip the bleed hose to
the battery box.

13.
Refit the top hose into its lugs on the fan cowl.

14.
Start and run engine until normal operating
temperature is reached, and check for leaks.

15.
Switch off engine and allow to cool.

16.
Check for leaks and top-up coolant to cold level

mark on expansion tank

Basically from what I understand.. with a "stone cold truck".. (might need 2 people) take bleed screw off and you want to undo and elevate the resevoir tank and raise it 8 inches above bleed hose.. pour coolant in res until it flows from bleed screew.. put bleed screw back in.. put res back in its place then top off and put cap on.. check after 2 days of use..

Thanks - I had read from Mike on an earlier post that these same directions were followed, but that they were not correct...I dunno...something about NOT bleeding the system with the resevoir cap off?

yes.. it was open for debate.. and Mike corrected the myth.. no need to start car and fill system or "cap off car started"..

Gotcha...I think I am clear. One thing I think we were not doing was raising the tank first....which may have caused an issue. We'll re-try with the tank raised - thanks!

raising the tank in very important to the bleed.

1. cold engine
2. loosen bleed screw
3. remove cap on tank
4. lift tank above bleed screw, be careful not to break plastic lines coming off tank. Ask me how I know
5. fill until you see a STEADY stream of fluid out of the bleed screw, then tighten
6. lower tank back into position fill it all the way to the top and put the cap on.
7. start truck and run with heat on full blast.

You can also leave the cap off and let the truck get up to operating temps to allow the system to "burp out all the air once the stat opens.

both have worked for me. the burp is good if you don't or didn't lift the tank
