Maybe we should do a bulk buy on scan gauges LOL

Hi Dale,
I did realise that I should have written "at least 3 years and 100k" on most coolants but I was wondering if anyone would leave their coolant for 3-10 years or 250 000k's? It's a bit like the ZF gearboxes being "sealed for life"? Which I guess is technically true, if you don't ever change the oil and the gearbox fails at whatever the K's then that is the life of the gearbox.......

Main issue with coolants is that they turn acidic over time. So as long as the PH is still acceptable and theres no dirt and crud circulating around then it "should" be ok

No worries. It was in my thinking due to the issues I have been having with the adaptor leaking and then failing.

Which is the precise reason I had mine changed. Donor engine has been in for 4 years and 65,000km and was 25,000km old when implanted. Even though one may assume that the coolant was new when the replacement engine was installed in the vehicle I decided to play safe and change the coolant. Which I think possibly saved me having some heartache if the coolant adaptor had failed completely unexpectedly...

The red OAT coolants turn black when they are contaminated and do draw iron as will be detected in a coolant test.
We had a CAT12H grader that had a faulty radiator cap,it turned the CAT OATcoolant(same as LR coolant) black.
We kept flushing the coolant and replacing,would turn black within weeks.I read the workshop manual,as part of the flushing there was an additional pipe out of sight that had a drain.Once that was flushed normality returned and the coolant stayed red.
20lt CAT extended life coolant(OAT) is around $100 for 20lt ready to use from any CAT dealer,it actually exceeds Land Rovers D2 Specs for OAT coolant.Pretty sure the coolant spec hasnt changed for the newer Discos.PLEASE CHECK before buying.

it had 202,000 when it had it's heart transplant. From memory the stealer had done a flush on it once or twice.


Probably would be worth getting yours checked though might be major surgery to get it out if it proves to have blockages.


There seems to be a plethora of these scan gadgets, I'd really like to know which is the better one without spending a fortune. Reading and clearing codes, reading vehciles specs on the fly especailly temps on engine and transmission would be very useful.


I drove old trucks and semis in my younger days so quite used to nursing engines up hills and allowing them to rest. You tend to get a feel for when an engine is stressed and not happy.


I don't understand the need to fly up a hill at mach 2 with cruise control on! Turbo would be at max boost, engine under max stress and people wonder why it got hot!

shame that torque pro don't do an app for iphones!




any suggestions for a good "dongle" ??

I reckon one good option is the Gap iiD Tool but it's not cheap. Its "Live Values" functionality gives you access to lots of data including temperature etc but it also does all the fault reading and clearing, as well as ECU flashing (older models), suspension height setting and CCF changes. You'd need to get the Bluetooth version so that you can put the live values onto your phone or tablet. And also a mount for your phone if you want to display values continuously while driving.

I came across a few OBDII dongles with Bluetooth (links below) but never went ahead due to getting the iiD Tool and considering it an "all-in-one" solution that suited my needs. These other ones seemed to have some good reviews but I have no personal experience with them. Suitability with Land Rover would need to be confirmed.
