That brings back memories of when I had go change the heater matrix, a right game. All that work just to feel a vague breeze after an hour of driving😄

[@AbelDoodeman]

whoahahahaha. ketamine........... again a smile on my face because of your humor. keep up the good work please!

[@BritannicaRestorations]

Thanks, will do!

[@mikebrennan6165]

Had this a few times on three different landrovers with seized fans squirting WD40 in and giving the motor a spin by hand without taking it out. worked every time although car ponged of WD40 for a few weeks!

[@weaton25]

As having a good working heater is so important in Canada with it being so cold in winter I think this is one time when it is worth spending the money and getting a new one that is not going to go wrong in a few months time after all it is not a quick job to do.

[@BritannicaRestorations]

Yes time is money - the blower is C$369

[@dpd6401]

Love your perseverance

[@rickbear7249]

Two tips that some of you might find useful: 1) before spraying the WD-40 penetrating oil, get some Isopropyl Alcohol (IPA) in there and, if you can, actually run the motor for several minutes. IPA is an electrical contact cleaner, so it's a partial refurbishment of the motor. You can actually "run in" and improve 12V electric motors by running them *submerged* in IPA, would you believe! 2) you may find that the blower heater unit has a wedge-shaped foam rubber gasket between the heater and the passenger bulkhead. This can make refitting the attachment bolts a pain, as you're trying to press against the foam rubber gasket while attempting to fix nuts-n-bolts. As I was about to give up on my solo repair, my Landy lost patience with me! She popped out that dummy air intake grill an the left side of the front wing. Looking through the hole it left in the wing, I saw it was a convenient place to insert a crowbar, to leverage the heater backwards while I got those bolts fitted inside the passenger side footwell. Job done. Anyhow, thanks for producing and sharing these videos. What did people do before KZbin?

[@BritannicaRestorations]

I now put captive nuts in the footwell where the bottom nuts and bolts should go - - now a one-man operation and a lot simpler!

[@rickbear7249]

@@BritannicaRestorations good idea. But I'm hoping not to be switching heaters too often. Your suggestion is probably also worth considering elsewhere on the Landy. Thanks

[@DietrichLopan]

Had the same problem with the blower motor on my Series. I ended up taking the motor apart, cleaned it up, lubricated it and now it's fine. I'd put a snow cowl on that air intake to help limit the ingress of water and future problems.

[@davidyeates5525]

Great effort. A lot of people forgetting them these days and just finding a place to fit a cheap chinesium diesel heater instead.

[@BritannicaRestorations]

Cheaper than a blower @ £145!

[@nickboylen6873]

The Eberspacher heaters and their various copies (including Chinese) have the advantage of using on,y a tiny amount of fuel for a decent amount of heat. They don’t need the engine running, so save on engine wear, fuel and noise. Besides, the cabin heater overcools the engine at idle in temperatures of less than 10oC, so are not much use for stationary vehicles in Arctic conditions!

[@MrRobmellor]

I have had to do this job so many times , but you make it look so easy, and the bad language, WERE!! was it. A great set of videos coming out of this Malawi motor. I found dieasypan helped, never tried Ketamine. Keep safe Mike, Yorkshire Rob.

Both the heater on my Puma and my wolf are fantastic, especially with a fume curtain in the wolf, seriously hot and blows so well! 24v obviously but can’t understand why they are so mega expensive to replace. Thanks Mike. Running out of tunnocks now with all the great videos you’ve put out recently. 😊👍🏻

[@BritannicaRestorations]

Yes the blowers are so expensive for what they are C$369!

[@carltonr3417]

Perfect timing! I’ve been contemplating this exact job but have been putting it off cause it’s summer and bloody hot and it’s a fiddle around to get the heater out. However, I want a working heater before it gets cold and this is the motivation I need to pull it out. It’s right hand drive with AC so those two little bolts at the bottom are what’s holding me up. Thankfully the AC is already disconnected.

[@BritannicaRestorations]

Go for it!

Hi Mike - Before you replace the unit can't you put rivnuts on those 2 awkward bottom bolts. Make any future work a lot simpler.

[@BritannicaRestorations]

Yes you could

[@DSouter1]

@@BritannicaRestorations so did you?

[@gazzafloss]

Mike I've done a few of those type of heater blowers on old Jags and they've always needed completely dismantling to free up. The armature shaft journals need rubbing down with a bit of "wet and dry" paper, lubricating with a little grease and usually run ok after that. They rarely burn out easily even though they can be stuck for years.

[@BritannicaRestorations]

Problem is getting the plastic fan off without destroying it - the shaft rusts and expands the plastic - there is nowhere to pry it off - and if you warm it and lucky to get it off - then refitting is a nightmare as the shaft is now sanded down to get the cover off - you just cannot win! You could buy the fans separately but not any more

[@gazzafloss]

@@BritannicaRestorations yes of course, the old Jag fans were all steel Smith's units, with a type of metal collet fitting holding fan drum to the shaft, "ah, them were the days", pure luxury...

[@philparr2724]

Hi Mike, Best upgrade is to fit the TD5 matrix into the heater and seal it , I had to turn my heater down on a summer day in Cumbria

[@BritannicaRestorations]

The 300Tdi matrix is the same size as the Td5, but with the hoses in a different place

[@philparr2724]

Hi Mike, no, pipes same as 300tdi but has a better core, the biggest prob is that the top and bottom tanks are larger so the openings have to be enlarged, but its worth the effort , my window demisters now work....

[@nickboylen6873]

It’s not the design that made a difference but the fact that it was new and unclogged with sediment, scale or corrosion.

[@roy2689]

Hi Mike, getting the air trunking out didn't seem too bad by the looks of it, but wait until you get the later defender's with the the 2.4/2.2 transit engines, there's weeks of mirth in that after you've done that job, and as an aside the glow plugs will give you laughs for years to come...

My defender 110 blows on setting one but not on full power. The fan is free and very clean I cannot figure out why it won’t blow on the fast setting.

[@BritannicaRestorations]

Take off the instrument binnacle and swap the wires over on the back of the heater switch (green yellow, green purple) The blower will now work in position 2 but not 1 I would wager the resistor has blown in the heater blower - this is fitted to reduce speed on the position 1

[@1977Timp]

I will need to this job on my 90 1987.. it's left hand drive.. the fan doesn't work.. I'm considering replace it with something different..

Don't you have some kind of protective mat/cover to put on the painted wing so you don't scratch everything?

My blower has always been dodgy. It works only once the vehicle is up to normal operating temps. Blower never works on my 110 when it’s cold.

You can get a box that the heater fits in below the cubby but it is expensive I designed one but the cost of production was too high

@@BritannicaRestorations Yesterday I ordered a new centre seat cover from YRM - I was not willing to cut up my original.

[@greebo7857]

Hmm... wonder if the Defender heater would be a good upgrade for my Series III..... 🤣🤣🤣

[@BritannicaRestorations]

Actually when they are working and not plugged up, they are not a bad heater - the thing that lets then down is the coolant is not hot enough and they pull cold, ambient air in When Jim and I were out in my 130 last weekend to pick up some furniture it was like an oven in my truck - I draw the air in from the footwell floor and the Isuzu puts out more hot coolant than the Tdi - it was too hot on the second speed!

[@warci]

don't bother: my series with a 45 year old heater core works miles better than my 300tdi ever did! Also the way the motor is integrated in the housing is terribly clumsy.

[@gsylass]

Look up T7 (or is it T17?) Design for upgrades if you must. Series split heater and fan and our series had a better heater than our 90!

[@tourettes4893]

I've got an old 'Smiths' heater in my Series II cab, it's a larger rectangle one, probably military. I've seen smaller round ones too in other series vehicles. (It's a heater core / radiator in a box with a fan, goes in the cab, hooks to flow & return pipes from coolant system) Advantage: Can be placed wherever you have room in the cab. Disadvantage: There is no room in the cab to begin with... .. :D

[@nickboylen6873]

I did exactly that and have a very good heater as a result. But it might be just as effective to recondition your existing blower (similar size, so probably similar airflow) and replace the heater matrix with new. Then just go around filling the holes in the casings, the lower fascia (usually got rust or screw holes from some accessory or bodged repair in the past), ensure the demister vent hoses are in place, the large grommets that seal the lower fascia to the demister hoses are in place, and replace the corrugated plastic hose from blower to matrix, as they get very brittle with age and split everywhere. On the water side, remove and clean out or replace the steel pipes along the head, the valve and various connections, and check the hoses. With good airflow, good coolant flow and correct control adjustment, they work pretty well for European winter conditions, even in a 109. The Defender type’s principal difference is how the temperature control works - it has an air diverted flap that directs the fan air through the matrix for full hot, around the matrix for cold, and wherever needed in between, while the SIII type has all air go through the matrix and the temperature control restricts coolant flow through the pipes. That means the Defender type responds more quickly to control changes, has less restrictions in the coolant pipes as is lacks the coolant control valve (also less likely to leak or seize), and can blow cold air faster as it is unrestricted by the matrix. But it is a bit of a faff to retrofit, mostly because of the blower intake position (won’t connect to SIII wing intake) and because you need to reverse the wiring polarity (simple enough).

They’re not bad if they’re clean and correctly set up. I get a lot of heat out of my standard Defender heater with a 200Tdi once the engine is warm. Certainly ample for UK conditions while driving, but the heater overcools the engine when idling. For Arctic conditions, a parking heater or something like a Webasto Thermotop would be very useful.
