Can this not be done by draining at the heat exchange unit on the inner chassis rail? 1982 88" 2.25 diesel

If only life were that easy.
LR deleted this somewhere post 2012. So no water pipes down there. Just a few mounting bolts. |

Sorry about that, mine is a 2.4, 2011. Did not know they had "improved" things.

Your right, no fuel cooler on 2.2 so no coolant pipes to drain from on near side chassis rail. So I had to drain by removing pipe from oil cooler thermostat spigot. Due to location it means you can’t get all the coolant into a single bucket , so need lots of strategically placed containers to catch as much as possible. When drained I hosed all the chassis, in the chassis, and all under the truck to wash away residue.
As you did you also need to drain the rad separately to get the max of the coolant out. The clamp on the oil cooler pipe is the spring type, so I used a small set of mole grips to open up and clamp open, then twist and wiggle the pipe off the spigot. It’s not difficult to do while under the vehicle, Just fiddly. Plus wear goggles and something waterproof as you will get wet and you don’t want coolant in your eyes. It’s not a design that helps a DIYer, if on ramps it would be a lot easier, but given you only need to do once every 10 years it’s worth getting as much of the original coolant out when you do. |

My 2.2 has a fuel cooler. Maybe left overs from the 2.4? 1988 90 Hard Top, 19J Diesel Turbo, Shire Blue - Restoration ongoing

They may well have kept it for vehicles heading for hotter climates....or as ever they had some in the parts bin when yours was on the production line so fitted it. You never know with LR

The presence or not of a fuel cooler isn't specifically linked to the engine being a 2.2. The change happened during the 2013MY. Darren

Any idea why they stopped fitting it in 2013 LRA ? I assumed it was something to do with the different fuel setup due to the 2.2 having a pump in the tank.

No, sorry. It's just something that I noticed from the VIN number that marked the change. It could be the result of some sort of cost saving review where it was found to be unnecessary, but that's just a guess. Darren

On a slightly related topic, how to drain the 2.4 via the fuel cooler? Which hoses to yank? The last time I tried to yank of the hoses, pressing down on the release buttons of course, they wouldn't come off!
I've recently seen what looks like rust dust and bits in my coolant so it's time to drain, flush, and refill with proper coolant Advice and tips welcome Thanks!  |
