Cooling Observations - just info
This a series of observation on my Disco cooling post 2 in lift.
State of the Disco and Cooling system
Prior to the lift my Disco ran 188 to 194 depending on speed and terrain. I am in BC outside of Vancouver so lots of mixed hills and flats.
At a light and idling for sometime 194 to 204 ish depending on driving prior off the freeway higher, lower if I was just driving around town
The lift netted me about 2 1/4 inches my OEM springs were shot.
As part of the lift, I needed to hunt down a battery drain - still have not found it - it is random
Work done :
Since the lift my Disco runs 183 on average and coasting down hill has hit 171-177 for short periods, averages 188 at lights with the odd pop up to 194-197 if I hit a bunch of lights in a row, this is with heating system turned off
The point of this post is to point out that the cooling system in these trucks seems to affected by a lot of factors, I would not have expected the change in temps from anything that was done, excepting possibly the radiator shroud.
It is possible the aux cooling fan is coming on, when it should not that still needs to be checked.
I am not really looking for a cause, I just wanted point out I what occured on my Disco.
So if you are having cooling issues check everything, not just AF and your fan and clutch. All the bits that generate heat, it could be something unexpected or overlooked.

Work done :
- 2 in Terrafirrma springs and OME shocks
- Topped up the Transfer case it was low
- Front drive shaft replaced
- Removed and cleaned up all my grounds (12 connections) on the drivers side and the battery posts
- Corrected the installation of the Radiator shroud (bottom clips were not on)
- removed and reseated the expansion bottle and cap - I replaced and hose clamp and did not get it quite tight enough
- No bleeding or additional Anti-freeze added

@Llamasayswhat My bet is the shroud, but I am not too worried about it. This was more of a heads up for others to check more than just coolant, fan and thermostat
