Had my gearbox flushed today (ZF 6HP26) at Keith Gott Landrover near Alton. This is at 90,560 miles, I think it's the first time the gearbox oil's been changed and it was well due to be done, picture of sample drained from the box prior to flushing:
They flushed and filled the box using a Wynn's megaflush machine, it took 12 litres in total which includes an allowance for the flushing which is then discarded. Here's what the new oil should look like (on the right side, thanks to RRPhil for this figure): 
Total cost £534.47 and the usual swift, friendly service from the Keith Gott service team. I was getting the occasional shunt on downshifts, so it will be interesting to see what the difference now is. I'll repeat the process along with a filter change when the Rangie hits 125,000 miles.

Found time today to give the old girl an oil service:
Next up is to give the paintwork a polish, and treat the underside and subframes with Lanoguard (and Dinitrol ML for the cavities). fanders --------------------------------------- 2009 4.2 SC Buckingham Blue 2021 Hilux 2.4 |

Following on from the recent gearbox rebuild carried out by Stephens Engineering in Ware (500 miles on the rebuilt gearbox so far and it's working perfectly), it's time to carry out an oil service and a few other maintenance items that are overdue. For planning maintenance I found it useful to put all the normal tasks on a summary sheet, so I can keep a track of what's due when. Here is the latest version of this:
I'm planning on doing: - Engine oil/filter change - Engine air filter change - Cabin air filter change - Supercharger oil change - BG44K fuel system cleaner - PAS fluid flush (probably using the syphon out & refill method) I'll take a few photos as I go for the thread here. Once I've done the above, I'll still need to do: - Brake fluid change (will probably wait until I fit overhauled/repainted Brembo calipers on the front, I have spares from my old TDV8 which should fit) - Replace thermostat and all coolant hoses (preventative maintenance) - Fuel filter replacement (preventative maintenance) I had a good go at inspection for rust and retreating/repainting/greasing the sills and rear arch lips last winter, so will probably also have a look at the other problem areas highlighted in the recent Youtube L322 rust spots video - things like front sub frame, brake lines behind front wheel arch etc. Again, I'll take some photos as I go. All good clean (well not really) fun keeping our L322 Rangies tip-top! fanders ---------------------------------------

Time for a bit more maintenance on the Rangie, aside from the regular items. First up, back in January, was replacement of the front strut/airbag assemblies with new BWI items from Advanced Factors. My 4.2SC has the damping masses screwed to the top of the struts which were a right sod to remove, being attached with decent threadlocker. I had to cut the bag off to mount the strut in the vice, and grind an old stilson wrench down to obtain the purchase to break them free:
Even then it took a bit of heat to free them off:
Whilst I was in the front wheel arches I rubbed a little corrosion off the steel brake lines, undercoated with epoxy primer before topcoating with chassis black and grease to extend their life:
I also noticed that one of the cooling pipes had come adrift from the bottom of the engine ECU box, due to a split in the plastic flange on the end of the pipe. This is the return pipe for air-conditioned air which is fed into the ECU box for cooling. It looked like it had been badly assembled at some point. I couldn't find the part number for a new one, so repaired the broken flange with thin copper wire and RTV sealant, before fitting properly. Quite a satisfying small repair:

The next job was replacement of the main coolant radiator, which had been dripping coolant on the garage floor for a while and required coolant top-ups. I bought a pattern radiator from Advanced Factors (Euro Spares version), which seemed ok quality when it arrived. The OEM radiator on the car is BEHR.
First time I've had the viscous fan off, I don't (yet) own a 36mm open jaw spanner but had a 1 7/16" Elora spanner which fitted, plus the Powerful UK tool to hold the fan pulley. I reassembled with a touch of copperslip to aid removal next time. The offending radiator, which had been leaking from the lower sides at the joints. The system runs at 16 psi, so even pin holes will weep:
All back together again and running leak free:

Excellent progress and write up. Have you squirted waxoyl inside the tailgate?

Thanks! My tailgate seems fine, and the car lives in a dry garage which helps a lot, but you're right I should shoot some cavity wax in there. The only small areas of corrosion just starting are on the flat section of the profile below the bottom of the glass. That whole section of the tailgate (with the RANGE ROVER lettering on it) needs repainting anyway due to some deep scratches when the previous owner had a broken rear window, so it's on the list to have done at some point.

Back from a superb French holiday in the Auvergne, the Rangie performed flawlessly including cruising at 130kph for hours on empty motorways. The last night was a stay at the amazing Chateau de la Tour in Rivarennes, just south of the Brenne region. I cannot recommend this place highly enough, they opened a few weeks ago and were great hosts. The Rangie did look at home:

Over the past few weeks I had noticed a coolant leak on my tiled garage floor (Ecotile PVC tiles, very good product), which seemed to be getting worse. Having run for a bit by topping the coolant up, the time came for a proper investigation. I thought it likely that the new radiator I fitted earlier this year may be leaking, perhaps from one of the o-rings on the hoses which I hadn't replaced when I changed the radiator, but everything was dry at the front of the coolant system. Closer inspection revealed dripping coolant from the auxillary coolant pump on the left side of the engine bay, down near the left bank exhaust manifold. This small pump is tucked away behind a foil heat shield, together with two solenoid coolant valves:
The heat shield is secured with three 10mm nuts, the lower of which was a right bu**er to get to as access is limited due to the proximity of the left side of the engine:
I managed to get the lower nut off with my Harbour Freight flex-head long reach ratchet with a deep 10mm socket on the end: 
I bought this tool on my last US trip, having seen Christian use one on an LR Time youtube video. It was the only thing I had in my toolkit that worked, and access from below is worse than from above. With the heat shield removed, the auxillary coolant pump becomes visible, along with the leaking coolant:
This pump pushes coolant through the heater core, so I learned that my 4.2 supercharged has three coolant pumps - 1. Engine (belt-driven) coolant pump, 2. Supercharger (electric) coolant pump and now 3. Auxillary (electric) coolant pump. To remove the pump, the inlet and outlet hoses must be removed. These are held in place with wire clips, and some idiot at JLR designed these so the top of the wire clip is facing the chassis rail, rather than inwards towards the engine where access is (relatively) good. One needs to insert a pick or thin screwdriver to pull the wire clip away from the hose end fitting, before releasing the hose. It took me probably two hours of skinned knuckles before I finally had the hoses off and could release the pump.
This is the pump - it's a BMW part, p/n 6 904 541. I bought a salvage item for £30, a new pump is about £80:
Once removed, some material could be seen along the pump casing joint:
On splitting the pump, this turned out to be remains of the pump casing sealing o-ring which had been extruded out by the coolant pressure. I put this down to the heat of the left exhaust manifold, which is very close to the pump, probably softening the o-ring material in use.
I changed the pump for the salvage item and reassembled everything. No leaks were present when the engine was run, proving this failed pump o-ring was the cause of the leak. I hope this write-up helps someone else when trying to find the cause of a coolant leak on their L322. --------------------------------------- 2009 4.2 SC Buckingham Blue 2021 Hilux 2.4 |

I also changed the front and rear differential oils whilst the Rangie was in the garage. This was done at 21,800 miles since the last diff oil change, slightly longer than my planned 20,000 mile intervals. The oil drained from both diffs was dark but still 'oily' and no significant chips were present on the sump plug magnets. I refilled with the correct grade oils and fitted new sump plugs. Hopefully good for another 20,000 miles.
