Thanks mate. So i can cut and remove the whole thing, balls and all, and cap at vac pump end.... Gain some room under the hood.

Found this in the manual after looking for ages.

Thanks Mat.

Shouldnt have to cut anything it should all just unplug really.

Yeah i meant it in a "general" way. Think I'll get rid of the whole assembly. That bracket with the solenoids takes a bit of room.

Get rid of the egr cooler too. This will take a small amount of load off your cooling system

Yeah another to do item ... Should have done it when the coolant was dropped.

Changed the diesel filter today and installed my Uniden CB/Scanner.

So I am still unsure as what's happening with my cooling system. After losing that 200-300mL of coolant out of reservoir things have been funny.
For example my usual freeway drive to work / home and vice versa, max temps I will get 80-81. More if I really push it. Lately, even cruising, where usually it'll be around 79-80, it goes all the way to 85-86. I never see those temps unless car is really working.
Also, idling it'll always go back and settle at 75-76C, unless it is hot, 30C ambient temps etc... Lately it sits on 78-79. Comes down to 77 after a long time idling but it never settles on 76 any more.
Also coming to a halt at lights or get off the freeway. Temps always drop very quickly to idling temps... Lately they simmer on or around 79-80. This is all even during the cool days.

I know in the grand scheme of things these temperatures are absolutely nothing... But I'm wondering what and why has it changed. Hope there was no air buble or something that swallowed that bit of coolant.
Shes going to get pressure tested on Monday and i'll go from there .

1st thing I'd look at is the systems pressure cap. I had coolant loss like that and the cap wasn't sealing properly so it sucked air instead of the coolant back from the overflow.

Fair point mudnut. I have 3 caps on my system, radiator isn't pressurized, nor is the overflow tank one. But the header tank is the only pressure cap I have. Might have a look at it. I should have replaced all of those when my cooling system was redone. Mind you, I DID tinker around that area when I pulled out the dual battery system/tray. I could have disturbed something ... Might go grab some caps tomorrow.

Let's hope its a simple fix.
