Simon you're a genius! Love all these info and secrets. Thank you for all these defender videos. I recently got one and want to know everything about them. I'm a DIY person and love growing my knowledge.
I just tried this on mine and it doesn’t make the “boop, boop, boooop” noise as the flaps open. Perhaps that’s a configurable setting. Awesome find 👍 well done.
If the rad matrix is covered in mud, ideally it should be washed out from the fan side. I've seen some rads that superficially looked clean but the fins were actually hard packed deep into the core with dried dirt. This severely hampered engine cooling, intercooler and transmission cooling and, depending on the layering of radiators, the complete failure of the air conditioning as well.
Good info as usual. Never had that on my 08 Defender😂 Too much nonsense that could go wrong. Thermostat should take care of warm up and engine temperature.
Good work again Simon. This idea of washing the radiator from the back made me think of my underbody lance that I use for power washing the underside free of salt etc. It is a cranked steel tube with fan spray nozzle that connect to the Lance on my Nilfisk washer. I wonder if something similar but used at much lower power could work from the engine side. It is perfect for mud and salt anyway! Another thing for you to invent!! 😃😃😃Richard.
Regarding maintenance, do you have any insight on changing the oil and resetting oil change reminder if applicable? Your reviews on this vehicle has been so much help, more than my dealer! Thanks.
Many thanks for your recent radiator wash tip! This was going to be my next truck but, because of that, I am now going to trade my Disco 5 in for something else - any suggestions, seriously! I've gone back to using my 1985 90 despite the noise and lack of heating........
I've been following your videos 👍I tried it yesterday after three years and it was great. (I'd like to know one more question. Navigation Connected Services Licence Expiring) （ONLINE PACK Subscription expired） What should I do in China。
Hiya this just an observation and experience from cleaning mud plastered motorcross bikes Surely the direction of jetting water needs to be from engine side out to the front through the back of the rad. Jetting from the front is going to force / push stones and all the crap deeper into the fins.
Precisely. Except that everything is so enclosed these days, mainly to save cats lives [yes really] that it is exceptionally difficult to near the back of the rad, much less aim a jet methodically over the majority of its surface area.
I think that would be good but not sure how possible that is with the space provided... we cleaned it from the front when we had the car stripped down and it seemed to clean pretty well from the front.
@@hedydd2 yep totally agree Huw Maybe some kind of right angle attachment is needed for the end of the jet wash wand, I could do with one for cleaning my defender
Simon, would you be able to comment on the issue of the jet engine like roar coming from the operation of the cooling fan in the radiator of my 2024 Defender 110 2.0L 4 Cylinder Turbo? Runs for 1-3 minutes after engine shut off every time, extremely loud. I assume this is normal, just cooling down the turbo, but I have never heard anything like this on any vehicle. Forums and dealership seem to think this is "probably" normal, but nobody seems to know for sure. Thanks!
Heres a thing...when engine is cold the thermostat is not sending water to radiator so no need to shut flaps to help engine heat up quicker. however I get for drag and wading reasons why its there. :)
You ar ecorrect but there must be some benefit in covering the air passing over the engine etc.... like the old radiator muffs on the old cars ( which also had thermostats )
Hi 🙋♂️ I think 🤔 if you don’t mind you can make one ☝️ more separate video for Land Rover like Hidden features. But you always make great 😊 video no doubt. Thanks 🙏
Am I missing something with this demonstration! How can you show the flaps working opening & closing still fitted on the Defender when you have removed it to fit the winch? 🤔
You are indeed missing something... there are 2 sets of flaps... upper and lower We removed the lower flaps to fit the winch The upper flaps are all present and correct !
@@L663 Ah now! This fact was not mentioned in the Demonstration and I not knowing all the full bells & whistles of the New Defender just how would I know it has two sets of flaps.

There are apps for smartphones that work off a bluetooth sender connected to the OBD-2 test socket that enable just that. There are also devices to hold the phone and project its display on to the windscreen, rather than reading directly off the phone placed in a simple holder.

third try... it seems my comment is removed ? Hi Simon! Apropos "secret features", do you know maybe how to activate manually the "EXTENDED MODE" height? (it seems I cannot type a reference URL to my comment ??)
Yes they do close in wading but on the off road coarse i was on it was more muds and ruts with some big water filled dips... did not have time to change modes for each dip so left it in muds and ruts... would TR2 ( Auto ) have sensed water and closed the flaps... i doubt it is that good ?
Seems way more complicated than it needs to be. There’s way to many electrics on these now not disputing they are a great car but I do very much question the reliability and being able to fix them easily anywhere has gone. Cant see many farmers or contractors buying them as Commercials as much as I do think it’s a step forward I do feel landrover have missed what made the defender great
While I'm in a whiney frame of mind, what I really don't like on off-road or rough road vehicles is the habit of siting intercoolers down low in front of the front wheels, with vents or slats allowing warmed air out through the wheel arch liner. Firstly the intercoolers get covered in rubbish because they are low down [on some V engines there is one on each side], but the worse thing is that the sh1t that is thrown off the tyres sticks to the wheel arch liners and blocks the air exit slots. Power hosing inevitably washes muck into the cavity, filling behind the intercooler and in front of the wheelarch and ultimately adding a surprising amount of weight and limiting the cooling. Hope LR don't have any kind of radiator in that silly position like I had on a Q7 and, on one side, the Honda. The best solution for a Defender is an air-to-water intercooler positioned in the engine bay, but I don't know what LR have done Rant over.
Unfortunately for my cost I found out there is a small radiator right behind the fog light. I hit a deer almost at 5 mph when I hit it and the trim around the fog light pushed into the radiator. I had a look and no other damage than the pushed in trim. Was very happy. Then I heard water dripping. 😒. Luckily I was less than a mile away from home in NE USA. So it was cold. Got home quickly. Now waiting for parts to fix it. The dealer has no date on parts. Not available in the US or UK. PS. The deer walked away. I agree with you. Why would you put a radiator almost at the axle level in the front of an off road vehicle.. I am sure there is a good reason, not sure what.
The new Defender does indeed have a low down radiator in the arch... and you lead me to another point.... when in wading mode the flaps close to stop muddy water getting in the radiator... but there is no such protection for the arch mounted radiators
@@channadevassgunawardena4162 There is no valid reason. The designers of all such vehicles, particularly Land Rover's, needs a good thrashing on their bums by a hefty bloke wielding a willow branch. There are other, far better, solutions. I hate this 'trend' with a passion.
Saw one on UA-cam where they had moved the side radiator and most of the lower front bumper so exposing the front wheels about up to mid point for serious off-roading
My god, yet another peice of nonsense added that land rover can't even be botherd to tell you exists, or maybe they don't know it's there either, do they not fit thermostats in their vehicle's anymore?.every time they sell one instead of supplying an owners manual they should just give them a feature length video that you guy's have made because its by far more informative and accurate than anything the dealership or land rover could be botherd to supply a new customer,
It's not a new thing All im gonna say is Peterbilt 281 1954. I understand it's a feature but with how land rover are now it will brake the new Defender if you can even call it that is not a Defender it's not got a modular like the old one had so they took away the motor that the services use. Like BT needing to go over fields with the boom lift on the back, The water board, The power line people they all use the proper land rover Defender. Thats just a peace crap and only belongs with the other land rovers of today in the city's and towns driven by people who don't need them and then complain about the global warming and the price hike in the city's for the emissions zone.
Well if you have to find hidden secrets that have been added, by a third party instead of the builder selling it to you then it does beg the question a bit, ha and I wonder how long off road before all those fancy electric & plastic Louvre's stop working?? Not long I bet, after seeing all the vids on it i wouldn't trust it to do the shopping in let alone off roading anywhere remote.!!
Simon, your channel is better than the user manual for the Defender ... many thanks.
Yes I am not sure this is in the user manual - i have looked under sand mode and cleaning and i cannot see it in the manual !
This car is just fantastic. Thanks for letting us know about this - I’ve added a note on my phone...

Just wondering if there is a temporary mode to close these vanes for a short period of time if you are wading and don't want to flood engine bay?
When you select wading mode these close and protect the radiator - interestingly not the smaller radiators in the wheel arch area....

Shouldn't it close in wading mode to stop this happening in the first place? If not they might be able to add that.
