Getting hot after Dawes needle and 3"

[growler2058]

Ive just had the top tank removed system flushed and new coolant. It had been running 3C cooler. Coincidence that its gone up now the 3" and dawes etc have been added? Yeah I've got a scan gauge thats how i saw the temp go up. First time the factory gauge went above half to nearly "H"

[Hodge]

Silly and obvious questions... How is the coolant level? And has the system been bled properly ?
And while fitting the needle and dawes, maybe you've knocked something?..... I know when I was doing mine I knocked a hose to my header tank while undoing a vacuum hose near the vacuum solenoid. Heard a hiss and then coolant ran out.... As I said, dumb questions, but figured I'd ask.


And bloody hell 122C is getting really high.

[threedogs]

How many bog holes have you done lately {Love Day} included.
And X 2 with the others,, 122C is bloody hot you should of had
steam pouring out from under the bonnet, something would of failed IMO

I take it you parked uphill to "Burp" the system

[growler2058]

No bog holes for a long time, definitely not since the radiators been done. Coolant levels look fine. It was bled at the mechanics. As soon as i went down the hill the temps rapidly fell back down, within 30 seconds. No hissing no steam nadda

[threedogs]

So no steam etc @ 122C I'd say the gauge is giving a false reading some how.
wait till you have a proper gauge fitted and see if that makes a difference.
As I mentioned 122c would have steam hissing out even blowing a hose it
would have that much pressure

Making sure the ohm on the sender match the ohm of the gauge

Id be checking the settings on the Scan-Gauge

Did you notice where the OE needle was sitting??

NEarly upto the "H"

Over a few cold bevies I've just been thinking and looking back at when I had my CRD.
Ca'rs coolant temps would rocket at the smell of any hill.... My system was normal and this was before AND after the NADS.
It never got anywhere near what you have had mate. I think max it got to once was like 102C... And even that for me was panic stations... But the temps quickly recvered.
CRD's are known for higher EGT's but ... I'm not sure about coolant.

The same hill it would often go to 101 or 99. Now its jumped 20C i shat

Yeah I would have shat too . That's a big jump.

I have been playing around with my cars boost setup over the last few weeks and saw the same behaviour on hills when boost was low or the spool up rate slow. Set the Dawes to around 19 psi and close the needle valve. Then it's a case of slowly opening the valve and taking test drives until you find a balance you are happy with. Make sure the test drives also include highway speeds as I found that you can open the needle valve too much which will give you great torque down low but at 80-100kph there was not enough boost and power was terrible with high egt/water temp.
